## Anthropic in Advanced Talks to Acquire New York Developer Tools Startup Stainless for At Least $300M
Anthropic is in advanced negotiations to acquire Stainless, a New York-based developer tools startup, in a deal valued at a minimum of $300 million, according to a person with direct knowledge of the discussions. The potential acquisition would represent one of Anthropic's most significant moves to strengthen its developer ecosystem and integration infrastructure as competition in the AI sector intensifies.

Stainless specializes in helping developers generate software development kits—commonly known as SDKs—from application programming interfaces. The startup's tools streamline what has historically been a time-consuming process for engineering teams building products on third-party platforms. For Anthropic, acquiring Stainless would address a persistent friction point for developers working to integrate its AI models and services into their applications.

The reported deal signals Anthropic's continued push to expand beyond model development into the surrounding infrastructure that makes AI useful for enterprise and developer customers. The AI company, which has raised billions in funding and counts Amazon and Google as investors, faces growing pressure to demonstrate strategic depth against competitors including OpenAI and Google. The $300 million valuation, while unconfirmed, underscores the premium that major AI players place on developer tooling as they race to build out platform ecosystems. The deal remains in talks, and terms could still change.
