Anthropic announced Monday that Stainless, a startup founded by former Stripe engineer Alex Rattray, whose software is widely used by rival AI labs, including OpenAI and Google.
Anthropic did not disclose the terms of the deal. However, Info informed last week Anthropic was in talks to buy Sequoia Capital and Andreessen Horowitz-backed Stainless for more than $300 million.
The acquisition would take the major infrastructure provider away from Anthropic’s rivals. The company told TechCrunch that it will be shutting down all home ownership Stainless productsIncluding the SDK generator. An Anthropic spokesperson said that Stainless customers will still own the SDKs they’ve created to date and have full rights to modify and extend them as they see fit.
Founded in 2022, the New York-based startup has become popular in the burgeoning artificial intelligence industry for automating the creation and maintenance of software development kits, or SDKs — libraries that developers use to interact with APIs.
Rattray developed software It can take API specifications and turn them into production-ready SDKs in multiple programming languages, including Python, TypeScript, Kotlin, Go, and Java. It has become a popular tool because the platform automatically updates SDKs as APIs change, eliminating the time-consuming process of manually maintaining them.
Technology is especially valuable companies Anthropic builds AI agents that can connect to external software such as OpenAI, Google, Replicate, Runway, and Cloudflare and perform tasks on behalf of users. Stainless’s SDK tools are an easy way to build and maintain these connections – but going forward, the tools will only be available to Anthropic, not its competitors.
According to Anthropic, Stainless has powered the creation of every official Anthropic SDK since the early days of the API.
“I started Stainless because SDKs deserve as much care as the APIs they cover,” said Rattray in a press release published on Monday. “Anthropic was one of the first teams to bet on this with us. We’ve been watching what developers have been building on Claude over the past few years, which made it an easy decision to bring our teams together. The team continues to do what we love on the platform where it matters most.”
