Paxos
A deep tech venture platform for the AI era Paxos.vc

Operator-led diligence
Deal-by-deal capital

Awaiting quorum

Technical conviction is a collective judgment.

The challenge

Access is the bottleneck.

VCs

Expertise and early access, on a deadline.

Paid networks are noisy and conflicted.

Founders

Few experts to sharpen the story. Fewer buyers.

The value proposition goes untested.

Operators

Deep judgment, no path into deals.

No on-ramp from operating into investing.

The solution

One neutral platform.

Intelligence layer
Structured diligence & expert access Technical review run by people who have built and operated the systems in question — not a survey of opinions.
Capital layer
Co-investment, deal by deal One vehicle per investment. We never lead, and we don't compete with the round.

Experts power the diligence. Capital follows the conviction.

Operating model

We complement, never compete.

Never lead
Co-investment only We come in alongside the lead, on the round's terms.
Self-funding
Subscriptions cover the platform The diligence work sustains itself, so the capital decisions stay unconflicted.
Bidirectional
Deal flow runs both ways Rounds come in for diligence; technical opportunities flow back out as leads.

The people

Three tiers, rewarded for value created.

Who Full-time operators — senior product, engineering and AI leaders. Pre-filtered experts across our nine domains — active, not full-time. Decision-makers inside the enterprises that adopt this technology.
Role Own decisions, lead diligence, back founders. Source deals, run technical diligence. Validate demand — what enterprises actually buy.
Reward Carry, full deal flow, management fee. Co-investment, contributor carry pool. Co-investment on deals they validate.
Commitment All-in — lead the work, don't advise. Consistent contribution where you're strongest. A candid answer on what you'd buy.
