Corsair

Corsair is a Y Combinator-backed company that integration Layer for AI Agents. Based in New York, USA, the company participated in the Winter 2025 batch of Y Combinator.

What Corsair is:

Corsair gives you (or your agent) safe access to hundreds of integrations. It natively handles all integration plumbing. The only code you write is the code that's specific to your use case. Your data stays yours.

Why we wrote it:

Integrations make products capable. Integrations are also frustrating to write. If you look at any codebase with integrations, 95% of the code is identical. It's all just basic plumbing.

Corsair was part of Y Combinator's Winter 2025 cohort, has a team of approximately 2 employees, and is actively operating.
