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, Artificial Intelligence, AI Agents, Agentic, and Operating System.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/sdsa: open an issue to ask a question, or submit a pull request to add artifacts.
