The DCVC API Portfolio

About this paper

I read DCVC’s portfolio the way a machine reads it — not the deep-tech pitch, the evidence. DCVC (Data Collective Venture Capital) has built its name on backing hard science and hard infrastructure, and its public portfolio resolves into my catalog with 36 companies that ship a public API I could pull, parse, and score on the same rubric I apply to Stripe. That is a small book — an order of magnitude smaller than a16z’s 242 or YC’s 190 — and the smallness is the honest shape of a fund whose companies are more often a spacecraft or a fab than an endpoint. This report is about the 36 that do have an interface, because the interface is the part of a deep-tech company an integrator, an acquirer, or an agent can actually inspect.

The headline is a builder’s paradox. DCVC’s infrastructure founders instrument their own APIs for agents better than almost anyone — Gradle, Kentik, and SF Compute ship real hosted or self-hosted MCP servers, and companies most people have never heard of post agent-readiness scores of 75 to 80 — and yet the book has almost nothing at the top: just two companies clear the exemplar band on a mean composite of 50.6, eleven of twenty-four upper-band providers score a flat zero on governance, and exactly one company in the entire fund publishes an OAuth scope catalog. This is a portfolio built by builders instrumenting their own machines, not yet hardened for the regulated or consumer-facing use its own agent surfaces invite — and the report reads that signal company by company.

What's inside

1. Executive summary — the builder's paradox, and the ceiling that is the headline
2. The firm, and the book — the 36 API-bearing deep-tech companies
3. Portfolio decomposition — a data-and-compute infrastructure book
4. The composite Kin Score of the book — two exemplars and eleven governance zeros
5. Agent-readiness of the portfolio — real MCP servers, absent safety rails
6. The peer-fund benchmark — a small book among big ones, small-sample caveat and all
7. The crown jewels — provider-by-provider on the exemplars and the real agent surfaces
8. Standards and the agentic turn — why the gaps stop being pedantry
9. Security, auth, scopes, and compliance posture — one scope catalog in the whole fund
10. The infrastructure question, and the whitespace
11. The investable thesis — for DCVC, and for everyone reading it
