Automated SDK Generation Moves Into Enterprise Mainstream

Stainless, which automatically generates client libraries from API specifications, has raised $25 million in Series A funding. The company now serves OpenAI, Anthropic, Cloudflare, and fintech infrastructure providers—a client roster indicating that automated code generation has shed its early-adopter fringe. Enterprise platforms now trust these tools for critical customer-facing SDKs, a shift reflecting demonstrated quality gains and cost efficiencies across multi-language maintenance.
