SDSA

SDSA (stylized as /dev/agents) is a stealth-stage startup building what it describes as a next-generation operating system for AI agents, aiming to make agentic applications a robust part of everyday consumer software through new UI patterns, a reimagined privacy model, and a developer platform for shipping more capable apps. The company was founded by David Singleton (former Stripe CTO), Ficus Kirkpatrick, Hugo Barra, and Nicholas Jitkoff, and is backed by SV Angel. As of this profile the company is pre-product: sdsa.ai is a single marketing/recruiting page with no public API, developer documentation, SDKs, or developer portal yet available. This entry was added to the API Evangelist network as a portfolio lead and enriched with what is publicly verifiable.

SDSA is profiled on the APIs.io network. Tagged areas include Company, Ai, AI Agents, Agentic, and Operating System.
