Sequoia Capital has 116 portfolio companies tracked on the network, of which 111 — 96% — publish APIs indexed here. That is one of the highest in-network rates of any firm profiled so far.
Its highest-rated API providers are Stripe, Zapier, Notion, HubSpot, and Figma.

Twelve companies, all exemplar. Stripe at 84.7 is the highest composite in the table and one of the highest in the catalog — and the only agent-native band in it.
96% is a thesis, not an accident
A 96% in-network rate means almost every company Sequoia backs ships a public API. That is a statement about what the firm invests in: infrastructure, developer tools, and B2B software where the API is the distribution channel.
Compare it to a generalist fund’s book, where consumer, biotech, and hardware positions have no API surface at all and the rate falls well below half. Sequoia’s number is what a software-and-infrastructure concentration looks like when you measure it from the outside, through artifacts rather than through a pitch deck.
Composite and agent readiness disagree
The two scores in that table do not track each other, and the gaps are instructive.
Zapier scores 67.1 on agent readiness — the highest in the book — on just 13 APIs, against a 79.3 composite. A company whose entire product is machine-to-machine integration has, unsurprisingly, built the idempotency, error semantics, and auth clarity that agents need. It did not need 384 endpoints to do it.
Temporal and Okta invert it. Both are exemplar on composite (73.0 and 72.0) and sit in the low 40s on agent readiness. Excellent documentation and contracts, missing the specific things an autonomous consumer requires — verified idempotency, described error behaviour, a rate-limit signal in the contract rather than in a docs page.
Stripe leads on both, which is why it is the only agent-native entry. That combination is currently rare enough to be a differentiator and will not stay that way.
Takeaway
116 portfolio companies, 111 with indexed APIs, and a top twelve that is entirely exemplar. Sequoia’s book scores well because it is concentrated in companies whose product is consumed programmatically — and inside that book, composite quality and agent readiness are clearly two different achievements.
