Anthropic has acquired developer tools startup Stainless in a move aimed at strengthening its Claude ecosystem, particularly its API infrastructure and agent-based integrations.
Stainless is a New York-based developer platform founded in 2022 that helps companies automatically generate and maintain software development kits (SDKs) from APIs. Its tools are widely used by major tech firms, including AI companies and API providers, to simplify how developers connect services across systems.
While financial details of the acquisition have not been officially disclosed, earlier reports indicated that the deal is valued at over $300 million. The acquisition marks another step in Anthropic’s broader strategy to deepen its developer ecosystem as competition intensifies in the AI space.
According to company statements and reports, Stainless will help improve how Claude connects with external tools, data sources, and third-party APIs. This is especially important as Anthropic shifts its focus toward building more capable AI agents that can perform complex tasks across multiple systems rather than just responding to prompts.
The company said the acquisition is intended to enhance developer experience and strengthen the “connections between agents and external systems.” Stainless’ technology will now be integrated more closely into Anthropic’s Claude platform, which is already used widely by developers building AI-powered applications.
As part of the deal, most of Stainless’ team, including its founder Alex Rattray, is expected to join Anthropic. The move is also expected to phase out Stainless’ standalone hosted product, with its core capabilities being absorbed into Anthropic’s internal tools.
Anthropic has been rapidly expanding its developer ecosystem in recent months, positioning Claude as a strong alternative to other AI platforms by improving coding tools, integrations, and enterprise readiness.
