Fastn

Fastn is the embedded integration infrastructure for SaaS,powering native, multi-tenant integrations with minimal engineering effort. Put simply, it is about building AI products and features, often for other companies.

Who is it for? Mostly companies adding AI to a product. Alongside the main category they mention Artificial Intelligence (AI). They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Fastn is based in Austin, Texas. Their site is fastn.ai.

Before you commit, look at track record, data handling, and who owns the models. A short pilot with your real data tells you more than any demo.

If you have worked with Fastn, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
