Quantum founders pitch into a room where most "deep-tech" funds wrote one cheque three years ago and call it a thesis. We built this directory so you only spend time on investors who actually understand qubits, photonics, sensing or post-quantum crypto, and write follow-on cheques for it.
Three structural realities make generalist VC lists actively misleading for quantum founders.
Quantum hardware doesn't ship a beta in six months. A "dormant" fund by SaaS standards (no cheque in 12 months) can still be very much active in quantum. We use 18-month windows for liveness, same convention as The Quantum Insider and GQI.
Cryostats, dilution refrigerators, photonic foundry runs, clean-room access. Tickets and burn profiles look more like climate-hardware or semiconductors than enterprise software, and the funds willing to underwrite that reserve differently.
EU Quantum Flagship, national strategies (US, UK, FR, DE, NL, IL, CA, JP), corporate balance sheets (IBM, Honeywell, Bosch, BASF, Airbus). The cap-table mechanics, including IP carve-outs, government-backed tranches and export controls, diverge sharply from a typical SaaS Series A.
Most public lists conflate them. We split investors into four conviction tiers because a pure-play quantum fund and a generalist with one opportunistic cheque don't behave the same way in a round.
"We were three weeks into pitching a US deep-tech fund that hadn't actually signed a quantum cheque in two years. The directory's conviction tier flagged it instantly. We re-routed to a strategic CVC and a pure-play in Europe, both were in diligence within ten days."
Every feature answers one question: would this fund actually fund this quantum company at this stage?
Quantum cheques per year (3-year trailing), lead ratio, decision window, reserve pattern. Generalist deals (AI, biotech, climate) and follow-ons are excluded, only quantum cheques count.
Hardware, software, sensing, photonics, communications, post-quantum crypto, enabling tech. A neutral-atom hardware founder doesn't need a list of post-quantum crypto investors.
Quantum syndicates are tight, the same dozen names show up across most rounds. If you land one lead, the graph tells you the four or five funds most likely to round out the syndicate.
Save a 10-second founder profile, sub-field, stage, ticket, geo, sovereign-friendly or not, and every card tells you how it matches. No account, no email required.
We're an independent firm of finance operators sitting alongside deep-tech and quantum founders. We run the financial model, the data room, the raise narrative, the parts of a CFO function that don't need to be full-time, but absolutely need someone who's read a hardware burn profile before.
We kept answering the same question across our quantum mandates: "is this investor actually a fit for our round, or just on a public list?" Each answer required the same half-day of open-tab research, fund websites, portfolio scrapes, press releases, conference panels, ecosystem trackers. So we built it once, for the whole community.
Long-cycle financial models for cryo, photonic and ion-trap roadmaps. Raise prep that anticipates sovereign-tranche term sheets, IP carve-outs and export-control covenants. Strategic CVC negotiation. Board narratives for mixed sovereign / private syndicates. Priced by the day or the month, never by the fundraise. If the directory gave you a shortlist and you want help turning it into a closed round, talk to us.
A directory that takes money from the funds it lists isn't a directory. It's an ad network. Quantum is too small a community to play that game, everyone would know in a month.
