Composites Are About High Performance. So Are Events.

A startup event strategy needs the same discipline. Spend enough time around (deep-tech) startups and you start noticing a familiar pattern. The same founders appear at event after event: a composites conference this week, a startup competition the next, followed by an investor summit, a sustainability conference and another pitching session. The logic is understandable. Young companies need visibility, customers and investors, and there is always the hope that the next event will provide the breakthrough introduction. The problem is that events can very quickly become an activity rather than a strategy. Teams return with business cards, LinkedIn connections and a sense of having had many interesting conversations, yet surprisingly little changes in the months that follow. For startups, where both cash and management attention are scarce resources, this is an expensive habit. I prefer to think about events through the lens of sport. A serious athlete does not try to peak every weekend. A season is built around a small number of A-events: the competitions where performance really matters. Everything around them is preparation. Startups should approach their event calendars in much the same way: select a limited number of events, understand exactly why they matter, prepare for them months in advance and then execute with intensity. Building your brand versus going where your customers are There are, in my view, two main reasons for a startup to attend events. The first is to build a brand, which for a young industrial company is largely about building trust. An established supplier enters the market with years or decades of history, references and relationships behind its name. A startup has none of that. Particularly in composites, where qualification cycles are long and customers are understandably cautious about introducing new materials and manufacturing technologies, familiarity matters. For a startup, brand building is ultimately trust building. This is why a composites startup should establish itself visibly within the composites ecosystem. JEC World in Paris is the reference. This is where I experimented a lot to master the game when I was leading the marketing and business development activities at 9T Labs – see picture above. Depending on geographic priorities, CAMX may play a similar role in North America, alongside relevant events in China and regional events in markets such as DACH, India or Southeast Asia. At these industry events, I would encourage startups to be relatively broad. Speak with suppliers, potential customers, competitors, investors and people from applications you may not yet have considered. Explain the technology in depth. The objective is not only to generate immediate leads, but to anchor the company in people’s minds as a serious part of the composites industry. This is also where I believe having your own booth matters. If brand building is one of the objectives, visibility cannot be an afterthought. Many manufacturing and materials companies still take a fairly conservative approach to exhibition design, which actually creates an opportunity for startups. Make the company visible from a distance. Bring parts, samples and, where practical, machinery. Demonstrate the technology rather than covering the walls with paragraphs explaining it. Give visitors something they want to touch, discuss or photograph. You are a startup. You do not have to look like everybody else. And at the events where you are building your brand, you probably should not. The second reason for attending events is much more targeted: meeting the people who can move the business forward. Once a startup has selected its beachhead markets, its event strategy should follow those customers. If aerospace is a priority, composite events alone are not sufficient; you should also consider events such as the Paris Air Show or Farnborough. If aircraft interiors are specifically relevant, Aircraft Interiors Expo in Hamburg may be far more valuable than another general innovation conference. Find the reference events in the markets you have decided to win. And go where your customers go. The physical presence can be different there. You are not necessarily trying to build a major aerospace brand; you are trying to become a trusted supplier to aerospace companies. A smaller booth, a national pavilion, a startup zone or an association stand may therefore be entirely sufficient as a base for demonstrations and meetings. As customer relationships mature, an even stronger form of presence becomes possible: being represented on the booth of a customer or partner. If an established customer displays a component incorporating your technology and identifies you as the supplier, the credibility effect is difficult to replicate with your own marketing. You are no longer telling the market that the customer trusts you; the customer is demonstrating it publicly. Four A-events, prepared like campaigns Once the industry and end-market calendars have been mapped, prioritization becomes critical. My recommendation for most startups would be to identify no more than four genuine A-events per year. This does not mean attending only four events. There will always be smaller conferences, investor meetings and local gatherings worth visiting. But an A-event is different: it is an event around which a significant part of the organization aligns and for which the company is prepared to go all in. Four such events already mean running roughly one major campaign every quarter, because the event does not begin when the exhibition doors open. A-level events should be approached as two- to three-month campaigns, with the exhibition days at the heart of a much broader engagement effort. Proper preparation starts months earlier and should be reverse-planned from the event date. Four to six weeks before the event, for example, a startup could organize a webinar around a topic closely related to the problem it solves. Better still, where appropriate, it could host a small event at its own facility. The purpose should not be to spend 45 minutes explaining why the startup is wonderful. Bring in an external expert, a customer or a research partner. Share useful data or discuss an industry challenge. The aim is to aggregate a community around the problem where the company has something

The most digital companies in the world are opening coffee shops

The most digital companies in the world are opening coffee shops

The AI industry runs on GPUs, APIs and Discord servers. So why is an AI insurance startup valued at $4 billion signing a lease for a 24/7 café in Shoreditch? Corgi, the San Francisco insurtech that raised three rounds in eight weeks this summer (TechCrunch, July 2026), already runs two 24-hour cafés in San Francisco and Atlanta. Its London location on Great Eastern Street opens this month, with five more planned including New York (Sifted, July 2026). The pitch: give founders a place to work at 3am, and sell them AI liability insurance while they sip a “Brexspresso.” Is it working? The Mercury News reported in April that the San Francisco café was running at a loss with zero conversions to the insurance business (via Wikipedia). Investors funded three more rounds anyway. That tells you something about what the market believes physical presence is worth right now. AI companies are becoming event organizers Corgi is the extreme case. The pattern is everywhere. Anthropic held its first Code with Claude conference in May 2025 as a single-day event in San Francisco. One year later, it became an international tour: San Francisco on May 6, London on May 19, Tokyo on June 10, with a second SF day added because demand from independent developers exceeded capacity (Anthropic). OpenAI’s DevDay returns to San Francisco on September 29. ElevenLabs ran its Global Hackathon across 30 cities simultaneously last December and launched its own Summit. Lovable’s community events page lists hackathons from Barcelona to Bradford to Tbilisi, funded with credits and swag. Stripe, the company that made online payments invisible, now runs two event franchises: Stripe Sessions at Moscone Center in April, plus Stripe Tour, a global one-day roadshow hitting Paris, New York and other major cities. Even the investors backing these companies have become organizers. a16z presents Tech Week, a decentralized conference series across New York, San Francisco and Los Angeles that reached more than 740 events in New York alone in 2024 (Tech:NYC). The firm also runs a16z Build, an invite-only program of private dinners and retreats designed to connect early builders. A venture firm operating a citywide event franchise and a curated dinner circuit is a firm that treats community as an asset class. These are field marketing budgets that would have gone to paid social five years ago. When every feed is flooded with AI-generated content, a room full of verified humans becomes the scarce asset. The companies building the flood know this better than anyone. The money agrees While AI companies build community from scratch, institutional capital is buying live events at scale. Liberty Media completed its €4.2 billion acquisition of MotoGP in July 2025, adding it to a Formula One Group that also includes F1 and hospitality business Quint (Liberty Media). KKR acquired Superstruct Entertainment, operator of more than 80 festivals including Sziget, Sónar and Wacken Open Air, in a deal reported at €1.3 billion (Music Business Worldwide, June 2024). CVC joined as co-investor a few months later. And Ari Emanuel raised more than $2 billion from Apollo, RedBird and the Qatar Investment Authority to launch Mari, a holding company built to buy events: the Miami Open, the Madrid Open, Frieze, Barrett-Jackson (Bloomberg, October 2025). This week, Mari agreed to acquire ATG Entertainment, owner of 70 theaters across Broadway and the West End, in a deal reported at $6 billion (Axios, August 2026). “Live has only grown more powerful,” Emanuel said in the announcement. Read that list again. Sports, festivals, art fairs, theater. The smartest money in media is converging on one thesis: attention earned in person compounds in a way digital attention no longer does. What this means for founders Here is the contradiction worth sitting with. The companies automating knowledge work are the ones investing hardest in rooms, coffee and handshakes. They understand that when intelligence becomes a commodity, trust becomes the product. And trust still gets built face to face. For startup founders, the lesson is practical. Your customers, your investors and your future hires are recalibrating where they spend their scarce in-person time. The events that win their calendar slots will be smaller, more curated and more expensive to ignore. Where the two worlds meet If you work at an AI company or a scale-up that just discovered field marketing, here is the uncomfortable truth: the event industry has been perfecting this craft for decades. The people who run Web Summit, VivaTech or MWC have solved problems you are about to encounter, from audience acquisition costs to sponsor ROI to the logistics of moving 100,000 people through a venue. That is the room Sesame Summit puts you in. It is the conference of conferences: our annual gathering in Biarritz where leaders from Europe’s top event organizers meet the startups, investors and tech companies betting on IRL. Disclosure: I organize it, so read this with that in mind. But if the smartest money in media is paying billions for audiences that show up in person, spending two days with the people who build those audiences seems like a reasonable shortcut. If your company is doubling down on events this year, what would you want to learn from the organizers who have been doing this for 20 years?

Crowded exhibition hall with an empty startup village, only one startup exhibitor active.

The empty startup area: why tradeshows fail at startup sales

Picture this. A strategy director at a major exhibition calls with six weeks to go before the show. The brand new startup area has sold exactly one booth. The show runs on a multi-year cycle, so a failed launch means the whole concept probably gets cancelled before it gets a second chance. This is a composite of several conversations I’ve had this year, and the pattern is always the same. The organizer builds a startup area, assigns it to the existing sales team, waits, panics, then calls for help when the calendar has already decided the outcome. The diagnosis is simple: startup acquisition is a different business than exhibitor sales. Most organizers discover this too late. Here are the five reasons why. 1. They sell square meters to companies that buy outcomes A corporate exhibitor renews a booth the way it renews an insurance policy. There’s a budget line, a history, a floor plan discussion. The sales conversation is about location and dimensions. Startups have none of that. They buy pipeline, investor meetings, and proof that the show is worth their time. And their time is expensive: my rule of thumb is two full prep days for every event day, more if the team is small or the show is far. A founder deciding between your startup area and a customer roadshow is running an ROI calculation, and a rate card doesn’t answer it. A sales team trained on renewals and floor plans doesn’t speak this language. It’s nobody’s fault. It’s a different job. 2. They start the clock six months too late Startup areas usually get scoped after the main floor is sold. The launch lands a few months, sometimes a few weeks, before the show. Founders don’t work like that. They lock their event strategy two or three quarters ahead, because attending well requires prep: outreach, meeting scheduling, demo logistics, travel. A six-week sprint is competing against decisions that were made in the spring. The paradox is that organizers know this about their corporate exhibitors, who book 12 to 18 months out. Somehow the assumption becomes that startups, the most resource-constrained companies on the floor, can be converted on short notice. 3. They design the offer around what they can administer Here’s a real example, anonymized. One show’s main startup offer was a 60 percent discount, funded by a national grant. Great deal. One catch: only domestic startups qualified for it, at an international show. The offer wasn’t designed around the buyer. It was designed around available paperwork. The addressable pool shrank to a fraction of the relevant ecosystem, and everyone else got a full-price booth with no story attached. Startup offers that work are built the other way around: define which companies belong on that floor, then engineer the package (price, format, visibility, matchmaking) that makes their decision easy. Administration comes second. 4. They confuse margin kept with money made This one stings, because I’ve watched it happen twice this year. An organizer works with a partner on startup acquisition, hits targets, then decides to insource the next edition to keep the full margin. On a spreadsheet, it’s savings. In reality, the target gets missed, the area sits half-empty, and the organizer comes back mid-campaign asking for rescue. Some results are still possible at that point. The results a proper campaign would have delivered are gone. The full cost of insourcing shows up later: lost booth revenue, a weaker visitor experience in that zone, and a startup program that gets cancelled for “lack of demand.” Against that, the partner commission was the cheapest line on the P&L. 5. They run a program where they need a pipeline Startup acquisition compounds. Alumni come back. Competition applicants become exhibitors. Founders talk to each other, and a good experience at one edition sells the next one. None of that happens inside a one-off project. It requires a multi-year cadence: scouting, competitions, curated programs, follow-up between editions. Shows on two or four year cycles feel this the hardest, because a standalone approach means restarting from zero every single time, with a new team and no institutional memory. What compounding looks like JEC World, the composites industry show in Paris, is the counter-example, and yes, they’re our client, which is exactly the point. The startup work there is a bundle, built over multiple editions: a startup competition that lowers the barrier for first-time startup exhibitors, an Investor Day that brings capital to the floor and gives founders a concrete ROI reason to attend, and a startup village that gives them a curated home inside a very large show. Each piece feeds the others. Startups apply because clients & investors are there. Investors come because the startups are curated. And the ones that grow don’t disappear: they graduate into regular exhibitors. That’s the part most organizers miss. A startup exhibitor is just a first-time exhibitor. Treated well, they’re the cheapest exhibitor acquisition channel you’ll ever have. Treated as filler for a leftover corner of the floor plan, they don’t come back, and neither do the ones watching. The question for organizers If you run a show with a startup area, ask yourself one thing: is it a strategy or a floor plan decision? If the honest answer is the second one, here’s my prediction. The area launches late, gets staffed by a team hired to sell something else, underperforms, and quietly disappears from the next edition. The internal conclusion will be “startups don’t work for our show.” The real conclusion is that the approach didn’t. Startups work fine. They’re just customers who need to be sold to like startups. Disclosure: Sesamers sells startup acquisition and curation services to event organizers. JEC World is a client. Read accordingly.

10 things founders can do during the summer event break

The event calendar goes quiet in July and August. Deadlines don’t. This article assumes you’re an early stage founder, pre-seed or seed at most, without a marketing team. You are the events team. The next eight weeks are the only window of the year where you can work on your startup event strategy instead of running it. Here’s how to use them, roughly in order of urgency. 1. Search for calls for speakers Most Q1 and Q2 2027 conferences select their speakers in autumn, which means applications open now. SXSW PanelPicker is the obvious one and since it closes on July 26th they always lack submissions from Europe. But every major event runs some version of it, usually buried three clicks deep on their website. Before you apply anywhere, build a speaker one-pager: your topic, three talking points, a short bio, one decent photo, and links to any previous talk. Program teams review hundreds of proposals. Make theirs easy. 2. Apply to startup competitions Autumn competitions open their calls in summer: One warning from someone who reads hundreds of these applications every year: judges can tell when ChatGPT wrote your answers. Roughly 80% of the applications I review show obvious AI usage, and the low-effort ones go straight to the no pile. Use AI to structure your thinking if you want. Write the answers yourself. Sophie wrote a full breakdown of how startup competitions work from the organizer’s side. Read it before you apply. Knowing what organizers optimize for changes how you write. 3. Apply to your country’s delegation for major events CES, MWC, Web Summit: most countries send an official startup delegation, and the selection happens months ahead. For CES only: Netherlands, France, Hong Kong, etc. A quick LinkedIn search gives you tons of results.  Delegations get you a subsidized booth, press attention you’d hardly get alone, and a cohort of founders going through the same thing. The application effort is low compared to what you get. The catch is timing: CES delegations typically close applications in September. 4. Get feedback from founders who exhibited in your industry Summer is the one season when people answer cold messages. Search LinkedIn for founders who exhibited at the last edition of the trade show you’re considering using its hashtag. Ask for 15 minutes. Ask three questions: what did it cost in total, how many qualified conversations did they have, and would they do it again. Three of these calls will teach you more than most post-event reports the organizer publishes.  That’s what we learned interviewing ReSnack founders. 5. Run a pitch practice session with your peers, and moderate it Get five founder friends on a call or around a table. Everyone pitches, everyone gives feedback. You moderate. The pitching part is obvious. The moderating part is the underrated one: keeping time, asking follow-ups, managing the room. That’s a skill you’ll need on every panel you ever join, and nobody teaches it. As Lubomila Jordanova told us on the Selected podcast, small formats with harsh feedback are where you learn to hold an audience. 6. Volunteer at a startup event Unglamorous advice, and one of the best access you’ll ever get. Volunteers see how the machine works from the inside: how speakers get booked, how the VIP room operates, who actually makes decisions. You’ll meet the organizing team, and organizing teams remember people who showed up to work. An obvious one is Slush where 1,800 volunteers come together to produce one of the best startup events on earth: https://slush.org/audience/volunteers  7. Plan a side event for the back-to-office season Every ecosystem has a September event where everyone reappears. For example FDDay in Paris. Don’t compete with the main program. Host a breakfast before it opens or drinks after it closes, 20 to 30 people, one clear theme. Side events cost a fraction of a booth and put you in the host position instead of the badge-wearing position. Start planning now: venues and calendars fill up faster than you’d expect for the first week of September. 8. Budget your 2027 event strategy Nobody wants to open a spreadsheet in July. Do it anyway, because budget season at your company happens whether you participate or not. The mistake founders make is counting the ticket and the flight and stopping there. Every event day requires two preparation days: outreach before, follow-up after. That’s the 2:1 rule, and it changes the math on which events deserve a slot at all.  Pick a maximum of 5 events for 2027. Assign each one a job: sales, hiring, fundraising, or press. If an event has no job, it has no budget line. 9. Check if your summer festival has a business track A growing number of music festivals run pitching sessions or networking programs alongside the main stage. Tomorrowland even hosts a dedicated event around impact & social innovation: Love Tomorrow Summit.  Is the deal flow serious? Sometimes. Is it the most pleasant place you’ll pitch all year? Definitely. If you’re on holiday near one anyway, the marginal cost is a badge upgrade. 10. Rest The circuit restarts in September and doesn’t stop until Christmas. Slush alone will take a week out of your life, and that’s before the follow-up emails. Founders treat rest as a productivity hack, which slightly misses the point. Take actual time off. Turn off the notifications. The events will still be there in September, and so will everyone else, looking exhausted already. Don’t be them. Photo credit: Anik Labreigne on Unsplash + Gemini

How Re.Snack Turns Trade Shows Into Revenue

The founders behind NUAGE, the sugar-free cotton candy rated Nutri-Score A, share their playbook for event strategy, budget, and pipeline ROI. If you’ve walked the aisles of a French food trade show recently, chances are you’ve seen — or tasted — a small cloud of the impossible: cotton candy with zero sugar and a Nutri-Score A. Behind it is Re.Snack, a startup founded in 2023 near Dijon by Vanessa and Florian, on a mission to reinvent confectionery. Their first product, NUAGE, is built on Sucr’A, a proprietary sugar substitute developed with AgroSup Dijon that uses plant fibres (isomalt and inulin) to recreate cotton candy’s signature melt-in-the-mouth texture — without sugar, allergens, colourants, or preservatives. The traction speaks for itself: revenue up from €200K to €7M in two years, distribution from 100 to 5,000 points of sale, more than 15,000 online orders, national TV exposure on M6 — and a reported acquisition offer from Lindt that the founders turned down. They’d rather build a brand than become a subcontractor. A sugar-free, fat-free popcorn is next. But what caught our attention is how they grew. For Re.Snack, trade shows aren’t a marketing expense — they’re the core of the sales machine, with a dedicated budget, pipeline targets, and hard ROI thresholds. So we sat down with the team and asked the five questions every founder should be able to answer about their event strategy. Sesamers: Let’s start with the basics. What role do events play in your sales motion — sourcing net-new pipeline, accelerating open deals, or closing? Re.Snack: Events are our number one growth channel. They generate new business, strengthen relationships with existing customers, and accelerate ongoing opportunities. In the food industry, people buy products, but they also buy the team behind them. Face-to-face interactions build trust much faster than emails or calls. That’s a big claim — number one channel. Does the budget reflect it? What share of your sales & marketing spend goes to events, and what target does it carry? Around 25% of our sales and marketing budget is dedicated to events. We consider them a strategic investment rather than a communication expense. Our objective is that every euro invested generates multiple times its value in qualified commercial opportunities over the following 12 months. Twelve months is a patient window. When you look across the whole portfolio of events, what does the blended pipeline ROI actually come out to? On average, we generate between 8x and 12x pipeline ROI across our major trade shows. Some flagship events, such as SIAL or ISM, can significantly outperform that because they concentrate the world’s key retail buyers in one place. Meetings are easy to count, revenue less so. Which events actually convert — not just into conversations, but into business? The events that convert best are those attended by decision-makers with active buying projects. For us, SIAL Paris, ISM, Snack Show, and major retail buying conventions consistently generate tangible business. Success isn’t measured by the number of meetings, but by the quality of follow-up and execution afterwards. Last one on the numbers: at what point do you decide an event has earned a bigger budget? What’s your threshold for scaling up? We increase investment once an event consistently delivers at least a 5x pipeline ROI and proves it can generate repeatable business over multiple editions. We look at long-term customer value rather than immediate sales, because retail cycles can take several months. Before we let you go — for the food founders reading this, what would be your top 5 events? My top five would be: What founders should take from this Beneath the answers sits a playbook any startup can copy, whatever the industry. Events have a job description. Re.Snack doesn’t attend trade shows to “be visible” — events source new business, deepen existing relationships, and accelerate open deals. If you can’t name the job an event does in your sales motion, you have travel expenses, not a strategy. The budget is an envelope with a target attached. A quarter of sales & marketing spend, set deliberately and measured against a pipeline expectation over 12 months. No target, no budget. ROI is measured blended, on a realistic clock. Individual events fluctuate; the portfolio number — 8–12x pipeline-to-cost in Re.Snack’s case — is what tells you whether the channel works. And the attribution window matches the sales cycle: judging a trade show by orders signed on the show floor would kill investments that pay off two quarters later. Conversion beats meetings, and follow-up is where ROI is made. The filter is decision-makers with active buying projects — not badge scans. The event budget implicitly includes the week after the show, not just the days of it. Budget growth follows proven return. A 5x floor, plus repeatability across multiple editions, before a single extra euro flows. One great year doesn’t unlock more spend; a pattern does. Run this way, events stop being a cost centre with nice catering — and become a growth channel with receipts.

Sesame Summit 2026 Workshop

Why events are lying about their metrics

This week I read about a hackathon claiming 6,000 attendees over a single weekend. The venues hosting it can’t accommodate more than 1,000 people. Nobody in the comments asked how the math worked. That gap between the claim and the room is what this article is about. For most event organizers, event metrics are marketing, not measurement. Once you understand how attendance numbers are built, why ROI stays a black box, and why matchmaking is often bad on purpose, you’ll read every post-event press release differently. Here’s a decoder. The vocabulary nobody explains to you The event industry has precise definitions. It just doesn’t advertise them. UFI, the global association of the exhibition industry, publishes calculation standards and auditing rules for all of them. Independent bodies like ABC audit against them. Here’s the short version. Visitor. One human being who came to the event. If I attend all three days, I’m one visitor. Visit. One entry through the doors. My three days now count as three visits. UFI accepts both figures in its audits, defines visits as visitors plus repeat visits, and requires the term used to be clearly indicated on the audit certificate. Guess which number ends up on the homepage. Attendee / participant. No standard definition. These are the marketing words. They can mean visitors, visits, registrants, exhibitor staff, speakers, press, students or the organizer’s own team, in any combination. When you read “50,000 participants,” you’re reading a number with no agreed method behind it. Registrant. Someone who signed up. Free registration events love this one, because no-show rates of 30 to 50 percent are common and registrations cost nothing to inflate. Exhibitor. Elastic too. UFI distinguishes direct exhibitors, who contract with the organizer, from co-exhibitors, who are part of a shared stand (think country pavilions). Both count. Daily exhibitor. A company present for a single day, typical in startup zones and rotating programs. A startup using a shared booth on day 2 only counts as one exhibitor, exactly like the anchor brand that paid for 400 sqm across the full show. Pavilion / delegation. A block of space booked by one entity, usually a national export agency, a region or a corporate, then filled with smaller companies. One contract, one invoice, 25 logos. Pavilions are how organizers cluster small booths into themed areas, and how “1,200 exhibitors” can describe wildly different realities. Net vs. gross exhibition space. Net is the square meters actually rented. Gross includes aisles, catering areas and that giant entrance arch. As a rule of thumb: net space is 50% of gross space at an average show.  The prosumer padding One more layer on the attendance side. Many events count audiences that are professional on paper only. Student groups bused in for the afternoon. Employees of a corporate partner who run one workshop on day 3. Startup founders’ plus-ones. Locals with a discounted badge. I’m not saying these people have no place at events. Some of the best energy on a show floor comes from them. But if you’re an exhibitor paying for access to buyers, a headline number that mixes procurement directors with second-year students is not relevant. Ask for the audience breakdown by profile. If the organizer can’t produce one, that tells you something too. The ROI black box Here’s the uncomfortable part: almost nobody wants to know if an event actually performs. CEIR, the research arm of the U.S. industry association IAEE, paused its exhibitor spend research for years and only resumed it in late 2025. Its 2026 Marketing Spend Decision Report finds that management evaluates exhibition ROI mainly on lead volume and post-show closed deals, and documents a gap between what practitioners track and what leadership actually cares about. The industry’s reference dataset on exhibitor spending had not been refreshed since 2017. Read that again: the largest B2B marketing channel went eight years without updated benchmarks. The exhibitor side confirms the fog. Vendelux’s 2026 B2B Events Survey of 120+ marketing and events leaders found that 86 percent can’t accurately attribute ROI to events, and 98 percent struggle to justify event spend to leadership. Yet 80 percent are maintaining or growing their sponsorships anyway.  Organizers benefit from this fog. Some only release their data points after the event is over, when your booking decision for next year is already locked in early-bird pricing. Others share nothing beyond the headline number. Try asking for the seniority breakdown of last edition’s visitors, or the ratio of buyers to service providers walking the aisles. I wrote before that founders systematically underestimate what events cost them, hence my 2:1 preparation rule. The other side of that equation is just as broken: they can’t estimate what events return, because the data to do so is withheld. The GDPR excuse When pushed, some organizers invoke GDPR as the reason they can’t share more. Let’s be precise. GDPR restricts sharing personal data: names, emails, badge scans tied to individuals. It says nothing about aggregated, anonymized statistics. “42 percent of our visitors have purchasing authority” contains zero personal data. An organizer who can’t tell you that either doesn’t know it or doesn’t want you to know it. Neither answer is reassuring. If startups are solving it, ask why organizers aren’t A whole category of companies now exists to answer a question organizers could answer themselves: was this event worth it? Full disclosure: at Sesamers we’re building mytradeshow.ai on this exact gap, so I have a horse in this race. Here are five others working the same seam: Sit with the logic for a second. Organizers gather and process the registration data, the badge scans, the floor plans, the exhibitor contracts. They are the best-placed actors in the world to measure event performance. If third parties have to reconstruct that picture from the outside, it’s because the people holding the data have decided that transparency isn’t always in their interest. Bad matchmaking is a feature One last thing, and it’s my favorite. Whenever an event’s matchmaking is mediocre, don’t
