Methodology

How to read this data

Scope

Publicly listed AI startups connected to Y Combinator and a16z, from January 2024 through July 2026. The a16z portion covers public Speedrun companies and publicly announced investments; confidential investments are not visible in public data.

Classification

Each company gets one primary industry based on the market it serves. Business type — B2B, B2C, B2G, Mixed — is tracked independently, because who pays is a different question from where the problem lives.

Company count is founder attention

A large category means more founders are building there. It does not measure revenue, survival, market quality or future success — and it usually means more competition.

Funding confidence

Funding evidence has been deeply researched and audited, with accepted totals classified by confidence where a usable public amount or program minimum was available. Funding is shown for 1,494 of 1,495 companies; the rest are marked "Not yet researched", which is not a claim that they raised nothing.
