Stainless is helping OpenAI, Anthropic and others build SDKs for their APIs
Rattray, who studied economics at the University of Pennsylvania, has been building things for as long as he can remember, from an underground newspaper in high school to a bike-share program in college. Rattray picked up programming on the side while at UPenn, which led to a job at Stripe as an engineer on the developer platform team. At Stripe, Rattray helped to revamp API documentation and launch the system that powers Stripe's API client SDK.
