Top 100 Deep Tech Startups of 2026 Announced
Hello Tomorrow has published a list of the most promising startups in healthcare, energy, biotech, and computing. Among the leaders are projects in synthetic biology for carbon capture.
The Gist: What's Really Happening
The release of the Hello Tomorrow Global Challenge list is not just an annual ranking—it's a clear shift in how the global capital market values deep tech. In 2026, a jury including representatives from ASML, Honda Xcelerator Ventures, and Breakthrough Energy Discovery selected 100 startups from 4,800 applications across 108 countries. Behind this statistic lies a fundamentally new pattern: for the first time in the competition's history, synthetic biology for climate applications shares the stage with AI startups in terms of investor attention, rather than trailing behind digital technologies.
The key signal is the undeniable leadership of biotech projects focused on carbon capture. This is not an academic fad but a pragmatic calculation: direct air capture (DAC) technologies remain economically unviable at the current cost of $800–$1,300 per ton of CO2. Synthetic biology promises to lower that threshold to $50–$100 per ton by using genetically modified microorganisms as self-replicating catalysts. It is this economic logic that the Hello Tomorrow experts have grasped, placing carbon-capture biotech startups at the center of their list.
Timeline and Context
The competition has been held since 2011, but the 2026 edition marks a turning point. The selection took place early in the year, and the list was published on April 23, 2026. The global competition finals are scheduled for June 11–12, 2026, in Amsterdam, bringing together over 3,000 participants from science, entrepreneurship, and investment. Evaluation was based on four criteria: technological innovation, economic viability, potential impact, and team strength.
Contextually, 2026 is the year when venture investors began to massively reassess the AI sector, shifting focus from model scale to economic efficiency and real-world applicability. Against this backdrop, biotech startups promising concrete results in tons of captured carbon appear to many investors as a more predictable investment than yet another foundation model with unclear monetization.
A parallel reality is the maturity of infrastructure AI projects. Tomorrow.io raised $175 million to deploy a satellite constellation for AI meteorology; Positron AI raised $230 million at a valuation of over $1 billion for energy-efficient inference. These deals show that AI is not losing its appeal, but interest is shifting toward hardware and infrastructure rather than pure-software solutions.
Who Wins and Who Loses
Winners:
Startups at the intersection of synthetic biology and climate. Arctic Capture already claims the ability to achieve CO2 capture costs of around $50 per ton using CRISPR-modified bacteria and automated robotic biomass cultivation systems. Inclusion of such projects in the top 100 opens access to the Hello Tomorrow network of over 30,000 investors and corporate partners.
LanzaTech not only made the list but also announced on May 10, 2026, a two-year partnership with the Technical University of Denmark to build a C1 bio-factory for converting industrial emissions into bioproducts. They spent 15 years developing tools for genetic engineering of non-model microorganisms, and now this expertise is translating into global recognition and institutional partnerships.
Investors who diversified their portfolios from pure AI into deep tech in time. HarbourVest Partners, which invested in Tomorrow.io, explicitly cites a "rare combination of differentiated technology and real commercial traction" as their selection criterion.
Losers:
Traditional DAC companies without a biological component. At $800–$1,300 per ton, they lose the economics to the biotech approach outright. If any of the top 100 achieve the $50–$100 per ton threshold, the market for DAC solutions without a biological component could collapse faster than expected.
Startups that applied but did not make the top 100. The gap between 100th and 101st place is not just about prestige—it's about access to the closed network of Hello Tomorrow investors and partners. For many young companies, this could be a critical loss.
Venture funds that over-invested in pure AI at the peak of the hype in 2024–2025. The shift in interest toward biotech and infrastructure AI means that some AI startups that raised large rounds may not secure their next tranche of funding.
What the Media Isn't Saying
Most publications focus on the fact of the list's publication and a few prominent examples, but miss the main non-obvious insight: through its competition, Hello Tomorrow is effectively shaping a global M&A funnel for corporate giants. The jury includes L'Oréal, ASML, Honda Xcelerator Ventures, and Breakthrough Energy Discovery. These are not philanthropists—they are technology hunters using the ranking to early-detect acquisition targets or strategic investments. A startup on the list gets not just PR but automatic visibility before corporate scouts from billion-dollar companies.
The second underestimated aspect is the geographic shift. 4,800 applications from 108 countries mean deep tech is no longer the preserve of Silicon Valley, Boston, and London. The list certainly includes teams from emerging economies, reflecting a fundamental change: scientific talent no longer has to emigrate to create globally competitive products.
The third point concerns ties with educational institutions. The success of LanzaTech, which built a partnership with DTU, and Arctic Capture, using CRISPR technologies, shows that university research and the startup ecosystem are merging ever more closely. Hello Tomorrow serves as a catalyst for this process, providing academic spin-offs with a platform to meet investors.
Finally, the selection methodology. The jury evaluates teams, not just technologies. This means a brilliant scientific idea without entrepreneurial experience may lose to a less groundbreaking but more feasible concept from a team with a track record. This approach shapes a certain type of startup—balancing science and business rather than retreating into pure research.
Forecast: Next 30 Days and 90 Days
30 days (until June 10, 2026):
The main event of this period is preparation for the summit on June 11–12 in Amsterdam. In the coming weeks, a wave of announcements from startups on the list will follow, aiming to maximize attention before the in-person presentation to investors. Companies from categories with the highest representation in the list—biotech, energy, and advanced computing—will be especially active.
Simultaneously, closed pre-sale meetings will begin as part of Investor Day, where top-100 startups will get one-on-one slots with funds. Information about specific deals is unlikely to become public during this period, but the total volume of signed term sheets could exceed $500 million.
90 days (until August 9, 2026):
After the summit, a cycle of due diligence on agreements made at the event will begin. I expect that by mid-August, at least 15–20 startups from the list will announce the closing of rounds initiated at the summit. Large deals in the carbon-capture biotech segment are particularly likely—possibly involving corporate investors at the level of Breakthrough Energy.
Startups that showed strong results at the summit will start receiving strategic partnership offers from corporations whose representatives were on the jury. L'Oréal may show interest in biotech projects for sustainable materials, ASML in advanced computing, and Honda in mobility and energy.
The main takeaway: the Hello Tomorrow 2026 list signals the end of the era of pure AI dominance in venture consciousness. The market is entering a phase where "deep technology" means not only neural networks but also genetic engineering, new materials, and space infrastructure. And the carbon agenda in this new reality becomes not a moral imperative but an economic driver—which is far more convincing for market capital.
