Sesame Summit 2026 – application open

One year on, Hello Tomorrow grand winner tozero gets ready to scale

This time last year, Munich-based battery recycling startup tozero was getting ready to take to the stage at Centquatre Paris, and deliver a pitch that would crown it the grand winner of the Hello Tomorrow global deep tech startup competition. 

Today, the German startup and its team are preparing to build their first industrial plant. 

With the next edition of the Hello Tomorrow Global Summit just around the corner, marking its 10th anniversary, we caught up with tozero’s CEO and co-founder, Sarah Fleischer, to reflect on her team’s win last year and what’s on the horizon for the startup.

A virtuous circle for batteries

Tozero has developed a uniquely efficient process to recover valuable raw materials from recycled lithium-ion batteries, a hot topic in Europe, where most raw materials are still imported. Its water-based carbonation recovery process also avoids the use of harsh chemicals. With demand for battery materials set to only continue skyrocketing, its technology has the potential to play a central role in Europe’s green transition. 

That’s also what some high-profile investors are betting on. Despite only being founded in 2022, tozero has already raised €17 million, from investors such as NordicNinja, In-Q-Tel, Honda, JGC Group, Atlantic Labs, Verve Ventures and Possible Ventures — in addition to a €2.5 million grant from the European Innovation Council (EIC). 

This funding helped tozero establish a pilot plant that processes nine tons of battery waste per day. After making history as the first to deliver recycled lithium for industrial clients in Europe, full-scale industrial deployment will be its next milestone of many. Winning the Hello Tomorrow competition was another significant achievement.

The Hello Tomorrow experience 

Being selected as the most promising startup out of 5,000 global applications doesn’t happen every day. Fleischer described it as a very meaningful moment for the company, well beyond the trophy or prize money. 

One aspect was validation. “The team is always going to be impacted by this kind of win, it’s an external recognition that reminds us of why we’re doing what we’re doing,” she said. 

Some of the positive outcomes were even more tangible: According to Fleischer, last year’s award resulted in increased visibility and meaningful connections, including to Honda, now one of tozero’s investors. 

With around 3,500 attendees coming from all over the globe, all with a specific focus on deep tech, Fleischer also remarked on the value of such an environment as a founder.

“It’s easy to stay in your founder’s bubble, always thinking about investors or discussing with other founders, so being able to broaden your horizon at an event like that is very enriching,” she said. “I had conversations with really interesting people from across the spectrum, like a Nasa researcher or an editor at Nature, for example. That’s not the case at every conference I go to.”

Moving past roadblocks

Despite clear momentum so far, tozero faces the same challenges as many of their peers trying to scale deep tech innovation in Europe: legal hurdles. 

“Our biggest obstacles now are regulations, bureaucracy and administration. Don’t get me wrong, they’re all there for a reason, but it slows us down and takes away resources,” Fleischer said.

Compared to the U.S. and China, European startups often feel at a disadvantage. But while they are hoping to benefit from faster permitting, larger government subsidies and more flexible regulations, the reality is that the continent is still grappling with regulatory reforms and financing schemes that would be crucial to nurture deep tech innovation — and the devil is in the detail. 

Germany, for instance, has set up a ‘Startup Initiative’ specifically designed to allow innovative new companies to operate in a sort of ‘playground’ of regulatory flexibility. “The idea is great in theory,” Fleischer said, “but in practice, the country’s administration is so complex that the small town where we are located doesn’t even know it exists.”

As tozero endeavors to scale up, the question is as loud as ever: Will Europe adapt fast enough to support deep tech pioneers? One thing appears certain: tozero remains determined to forge ahead, but only time will tell if it can overcome hurdles as fast as its team would like.

In the meantime, the Hello Tomorrow Global Summit returns 13-14th March for its 10th anniversary with a new batch of deep tech startups shaping the future — stay tuned for more details.

Despite ongoing conflict, Ukrainian fintech companies continue demonstrating remarkable resilience in securing international investment, challenging preconceptions about wartime entrepreneurship in Europe’s eastern frontier. The latest proof comes from Fintech IT Group, which has successfully raised €16.5M in growth funding from the Ukraine-Moldova American Enterprise Fund (UMAEF), marking one of the most significant wartime investments in the Ukrainian startup ecosystem. This funding round represents more than capital allocation—it signals international confidence in Ukraine’s tech sector durability and the strategic importance of maintaining financial infrastructure during crisis periods. Ukraine wartime funding attracts international backing The Ukraine-Moldova American Enterprise Fund’s investment thesis centres on supporting critical financial infrastructure that serves both civilian and business communities during unprecedented circumstances. UMAEF, backed by the U.S. government, specifically targets companies providing essential services that maintain economic stability in challenging geopolitical environments. “We’re investing in companies that demonstrate not just financial potential, but strategic importance for regional economic resilience,” noted UMAEF representatives familiar with the deal. This approach differs markedly from traditional European venture capital, which typically prioritises pure growth metrics over strategic infrastructure value. The investment reflects broader international recognition that Ukrainian fintech companies have proven their operational capabilities under extreme stress conditions—a unique value proposition in European markets where regulatory compliance and operational resilience increasingly matter to institutional investors. Monobank’s European expansion strategy Fintech IT Group, operating primarily through its flagship Monobank platform, has established itself as Ukraine’s leading digital bank with over 7 million active users. The company’s mobile-first approach and robust API infrastructure have proven particularly valuable during wartime, when traditional banking channels face physical disruption. The €16.5M funding will primarily support technological infrastructure expansion and enhanced security measures, according to company leadership. This includes strengthening cross-border payment capabilities and developing additional financial products tailored for both domestic and international Ukrainian communities. “Our experience maintaining financial services during conflict has given us unique insights into building resilient fintech infrastructure,” explained Monobank leadership. “These capabilities position us well for expansion into other European markets where operational reliability is paramount.” The funding also enables deeper integration with European financial systems, potentially positioning Monobank as a bridge between Ukrainian diaspora communities and their homeland—a strategic advantage as refugee populations establish new lives across European capitals. This investment underscores how wartime innovation often produces solutions with broader European market applications, particularly in financial services where trust and reliability prove more valuable than flashy features. For Ukrainian startups, proving operational excellence under extreme conditions may well become their unique competitive advantage in European expansion.

The UK’s fintech landscape is witnessing a new wave of institutional backing as specialised accelerators emerge to bridge the gap between early-stage innovation and scalable growth. Against this backdrop, Antidote has secured €2.95M (£2.5M) in funding to launch its accelerator programme focused on fintech and Bitcoin-adjacent technologies. The funding signals renewed confidence in the UK’s position as a global fintech hub, despite ongoing regulatory uncertainties around digital assets. Led by Fulgur Ventures, the round reflects the growing appetite among European investors for infrastructure plays that can nurture the next generation of financial technology companies. The timing aligns with increasing institutional adoption of Bitcoin and digital assets across traditional finance, creating demand for specialised support structures. Fintech accelerator funding attracts specialist investors Fulgur Ventures’ decision to lead this round underscores the firm’s thesis around Bitcoin infrastructure and the tools needed to support mainstream adoption. The Venice-based venture capital firm, known for backing Lightning Network infrastructure companies and Bitcoin-native startups, sees Antidote as a strategic platform to identify and develop promising UK fintech talent. “The UK remains one of Europe’s most vibrant fintech ecosystems, but there’s a clear gap in specialised support for Bitcoin and crypto-adjacent innovations,” notes a Fulgur partner familiar with the investment. “Antidote’s approach combines traditional accelerator methodology with deep domain expertise in digital assets.” The investor’s portfolio strategy focuses on companies building critical infrastructure for Bitcoin adoption, from payment rails to custody solutions. Antidote fits this thesis by positioning itself as a talent pipeline for the next wave of Bitcoin-enabled financial services. Bridging traditional fintech with digital asset innovation Antidote’s programme targets the intersection between established fintech verticals and emerging digital asset opportunities. This positioning reflects broader market dynamics where traditional financial services increasingly integrate blockchain-based solutions, creating demand for hybrid expertise. The accelerator plans to support 8-12 startups per cohort, providing €50,000 in initial funding alongside mentorship from industry veterans. The programme specifically targets companies working on payment infrastructure, trading platforms, custody solutions, and compliance technology for digital assets. “We’re seeing exceptional talent in the UK who understand both traditional financial services and the technical nuances of Bitcoin,” explains Antidote’s founding team. “Our role is to provide the runway and expertise needed to turn these insights into scalable businesses.” The funding will support programme operations, mentor network development, and follow-on investment capacity for portfolio companies. Antidote also plans to establish partnerships with major UK financial institutions seeking exposure to digital asset innovation without direct investment risk. This launch reflects the maturation of Europe’s digital asset ecosystem, where specialised support infrastructure is emerging to complement general-purpose accelerators. With regulatory clarity improving across EU markets, accelerators like Antidote are positioning to capture the next wave of fintech innovation at the intersection of traditional finance and digital assets.

Germany’s tax advisory sector faces a looming crisis. With 57% of the country’s tax advisors aged over 50, the profession confronts both a demographic cliff and mounting pressure to digitalise decades-old processes. Into this gap steps AnyTax, which has secured €1 million in pre-seed funding from IBB Ventures to modernise Germany’s tax infrastructure through intelligent automation. The Berlin-based startup’s timing couldn’t be more strategic. As Germany’s Mittelstand grapples with increasingly complex tax regulations whilst traditional advisors edge towards retirement, AnyTax’s platform promises to bridge the growing expertise gap through technology that augments rather than replaces human judgment. German tax modernisation attracts strategic investment IBB Ventures’ investment reflects a broader recognition that Germany’s tax advisory market—worth billions annually—requires urgent technological intervention. The Berlin-based VC, backed by the city’s investment bank, has consistently backed companies addressing structural inefficiencies in German business processes. “The German tax system’s complexity creates both challenges and opportunities,” notes an IBB Ventures spokesperson. “AnyTax’s approach of augmenting advisor capabilities rather than replacing them aligns perfectly with how German professional services are evolving.” The funding round positions AnyTax within a growing cohort of European RegTech companies that specifically address continental European regulatory environments, rather than adapting Anglo-Saxon solutions. This localised approach proves increasingly valuable as EU member states maintain distinct professional service requirements. Addressing Germany’s tax advisor shortage through technology AnyTax’s platform targets the critical bottleneck facing German businesses: accessing quality tax advice amid advisor shortages. The company’s technology enables existing advisors to handle larger caseloads whilst maintaining compliance standards, effectively multiplying capacity within the existing professional framework. The startup’s solution addresses uniquely German challenges, including the complex interplay between federal and state tax obligations that confounds even sophisticated international businesses operating in Europe’s largest economy. By automating routine compliance tasks, AnyTax frees advisors to focus on strategic tax planning—precisely where human expertise adds most value. Founder insights suggest the €1 million will primarily fund platform development and partnerships with established German tax advisory firms, recognising that success requires deep integration with existing professional networks rather than attempting to bypass them entirely. AnyTax’s funding reflects broader momentum in European professional services technology, where regulatory complexity creates sustainable competitive moats for startups that truly understand local market dynamics. As Germany’s tax landscape grows increasingly sophisticated, platforms like AnyTax become essential infrastructure rather than mere efficiency tools.
