Infer0

infer0 is an API routing platform that lets end users connect their own AI provider keys and authorize apps to use them, solving the problem of provider lock-in and key management. It sells to developers and IT teams in B2B and B2B2C contexts, including startups and enterprises. The platform is positioned as a bring-your-own-intelligence solution, where developers integrate once using standard API formats and infer0 routes to any provider without code changes, while users maintain control over spend and access.
