The Deep Tech Investors Writing the Most Interesting Cheques in 2026

Deep tech now accounts for 36% of total global VC funding, up nearly three times since 2016, and the pace of acceleration is not slowing. U.S. private investment in computing equipment alone has roughly doubled since 2023, reaching $280 billion on an annualised basis in 2025. This is not a software-driven cycle dressed up in hardware clothing. It is a structural reallocation of capital toward companies building things that are genuinely hard to replicate, hard to commoditise, and hard to understand if you have not spent time inside a lab or on a factory floor. The investors winning in this environment are not generalists who wandered in from SaaS. They are specialists with the technical conviction to write cheques before the rest of the market knows what it is looking at.

The catalyst is well understood but often undersold. The release of ChatGPT in late 2022 did not just accelerate AI adoption; it exposed a critical infrastructure deficit across semiconductors, energy, and compute architecture that software alone cannot fix. Khosla Ventures is currently raising $3.5 billion, a signal of how seriously top-tier firms are treating this moment. Lux Capital, with $7 billion AUM and a $1.5 billion Fund IX closed recently, has been explicitly positioning around the industrial transformation thesis for years and is now watching that conviction pay out. The firms that were laughed at for backing physical-world science five years ago are now setting the agenda for where frontier capital goes next.

DCVC, managing $4 billion in AUM, has quietly become one of the most technically rigorous firms in the market, with a portfolio that spans computational biology, advanced manufacturing, and AI infrastructure. Eclipse Ventures, also at $4 billion AUM, is writing cheques squarely at the intersection of software and industrial transformation, a thesis that looks more correct with every passing quarter. Flagship Pioneering sits at $14 billion AUM and remains the dominant force in life sciences deep tech, having incubated Moderna and continuing to run a company-creation model that most VCs cannot replicate. Prime Movers Lab and Playground Global, both around $1.2 billion AUM, are the firms to watch at the seed and Series A level, consistently backing founders in propulsion, energy, and advanced materials before larger funds are willing to price the risk. Boost VC, founded by Adam Draper and Brayton Williams with $200 million AUM, is writing the very first cheques at $500,000 pre-seed, making it one of the few institutional players willing to take on science at its most raw and uncertain stage.

"The best deep tech investors are not learning the technology from pitch decks. They already know it."

The individual investor profile matters as much as the firm. The most dangerous deep tech investor in the room right now is not the one with the biggest fund. It is the one who built something before they started writing cheques. Alex at Entrada Ventures co-founded Aurrion, a silicon photonics company he sold to Juniper Networks, and now evaluates technology at the level of architecture and integration pathways rather than relying on technical advisors to translate the risk. His early bets on d-Matrix and Coreshell were made before the broader market had a framework for pricing either company. That founder-turned-investor archetype is becoming the defining edge in deep tech, because the information asymmetry between a builder and a generalist is enormous when the underlying science is non-trivial. The best deep tech investors are not learning the technology from pitch decks. They already know it.

For founders, the implications are direct and actionable. Firms like Two Sigma Ventures, General Catalyst, and Index Ventures are increasingly active in deep tech, but their cheque sizes and diligence frameworks are built for companies with cleaner near-term revenue visibility. The firms genuinely suited to early deep tech, DCVC, Prime Movers Lab, Boost VC, Playground Global, and The Engine at $1 billion AUM, have built internal capabilities to sit with scientific uncertainty for longer than their generalist counterparts. Defense tech, which hit a record funding year in 2025 with In-Q-Tel and Founders Fund among the most active, is now its own distinct sub-category requiring investors with security clearance access and government procurement knowledge. Founders should be matching their capital source to the actual risk profile of their company, not to brand name or fund size.

The next 12 months will sharpen the divide between deep tech investors who have genuine domain depth and those who repositioned their websites after 2022 and called it a thesis. Khosla's $3.5 billion raise, Lux's Fund IX, and Flagship's continued dominance at $14 billion AUM suggest the top end of the market is consolidating around a small number of high-conviction specialists. The seed layer, occupied by Boost VC, Prime Movers Lab, and individual operators-turned-investors like Alex at Entrada, will remain the most interesting place to watch for what the next generation of deep tech categories actually looks like. The firms writing the most interesting cheques today are not following market consensus. They are creating it.
