QCT Capital

For founders

First cheque in for founders securing critical systems

We lead and co-lead pre-seed rounds and follow at seed. And because our studio already works with the buyers, we can help you win the first ones.

Introduce your company

What we back

Three areas, one test

Every company we back carries a security, privacy, trust, cryptographic or resilience advantage, sold into an industry that cannot afford to get it wrong.

  • Quantum security

    Cryptographic discovery and migration orchestration · PQC key management and crypto-agility · Quantum-safe identity, payments and custody protocols · QKD and QRNG integration for banks and telecoms

  • Cybersecurity for high-consequence sectors

    AI-enabled defence, detection and recovery · Exposure management · Secure infrastructure for finance and critical systems

  • AI security and privacy

    Agent identity and permissions · Model and application security, red-teaming and data controls · Confidential computing, MPC and FHE where deployment is practical

How we invest

Early, concentrated and hands-on

Stage
Lead or co-lead at pre-seed. Follow at seed. Selective Series A follow-ons.
Geography
Weighted to Israel, the UK, Switzerland and Europe, with selective US investments.
Ownership
Meaningful early stakes, with reserves concentrated in the strongest companies.

Beyond capital

What you get from QCT

  • Buyers, not just introductions

    Our studio works inside banks and regulated enterprises. Portfolio companies meet design partners who already trust us.

  • Diligence that doubles as product feedback

    A cryptographer and a security architect read your system the way a bank's review board will.

  • Talent you can't find on job boards

    Our network of cryptographers, security engineers and AI specialists who have shipped in regulated environments.

  • Studio support at disclosed rates

    Pilots, compliance evidence and architecture work from the studio, at discounted rates reported to our LP advisory committee.

  • Capital that follows

    We reserve capital to keep backing our strongest companies as they grow.

Save yourself time

What we won’t fund

If your company sits here, we are the wrong partner, and saying so early is a courtesy.

  • No broad blockchain thesis

    Exposure is incidental: only where it serves security, cryptography or regulated financial infrastructure.

  • No frontier quantum hardware

    Its capital intensity, duration and scientific underwriting do not fit an early-stage security fund.

  • No generic AI applications

    Every company we back carries a security, privacy, trust, cryptographic or resilience advantage.

  • No services disguised as ventures

    Studio projects must show repeatability, product potential and clean ownership before any spinout.
