Apertis has joined the Claude Startups program.

We're building model supply and delivery infrastructure for teams bringing AI agents into production: organization-scoped keys, budgets, cost attribution and audit trails behind one OpenAI-compatible API.

The program gives our own team Claude to build with, and time with Anthropic's team. Both go straight into what we ship next.

Apertis joins the Claude Startups program. STIMA AI, the company behind Apertis, has joined the Claude Startups program. Apertis AI 2.2.108, Oct 7, 2026.
