The GV (Google Ventures) API Portfolio

About this paper

I read GV’s portfolio the way a machine reads it — not the pitch, the evidence. Google Ventures, Alphabet’s independent venture arm, resolves to a broad, later-stage, category-leader book in my catalog, and 121 of its companies ship a public API I could pull, parse, and score on the same rubric I apply to Stripe. This report is about those 121, because the interface is the part of a company an integrator, an acquirer, or an agent can actually inspect — and a fund’s book of APIs is a truer signal of the fund’s bet than its thesis page.

The headline carries an irony. GV is the venture arm of the company building the agentic web — the maker of Gemini, the author of the Agent-to-Agent protocol — and it holds the least agent-instrumented API book of any fund I can measure at its scale: just 37% of its API providers are agent-native, the lowest rate of the deeply-harvested majors save one. Behind a single towering exemplar — Stripe at 84.5 — the book falls off a cliff, five names clear the 70-point line, and the mean settles at 48.5, near the bottom of the peer set. GV backs the operators who define categories — HubSpot, Slack, GitLab, DocuSign, Stripe — but famous is not the same as agent-ready, and outside its small payments cluster this is an OpenAPI-broad, agent-shallow book. This report reads that signal company by company: the practice-area decomposition, the Kin Score facet-by-facet, the twelve-dimension agent-readiness table, the head-to-head against ten rival funds, and the punch-list of what even the crown jewels have not shipped.
