The startup that auto-generated production-ready API SDKs in Python, TypeScript, Go, Java, and Kotlin. Used by OpenAI, Google, Cloudflare, Replicate, Runway, and Meta. Anthropic acquired it for $300M+ and immediately announced it would wind down all hosted products — a strategic kill to deny competitors access to critical infrastructure.

Collateral damage: OpenAI, Google, Cloudflare, Meta, and dozens of companies lost automated SDK generation. Existing SDKs frozen in time.
