Archastro

ArchAstro is a Seattle-area startup building a runtime for cross-company AI agents: privacy-aware agents deployed on both sides of a business relationship that collaborate on integrations, migrations, upgrades, onboarding, testing, and bug fixes, with shared test visibility and human approval gates. The ArchAstro Platform API is an agent-first developer control plane covering users, teams, agents, routines, threads, messages, knowledge, tools, installations, workflows, sandboxes, integrations, and inbound webhooks, with first-party TypeScript and Python SDKs and a CLI. Founded in 2026 by engineering veterans from Microsoft, Stripe, Statsig, and Meta; backed by a $6.2M pre-seed.

Archastro publishes 10 APIs on the APIs.io network, including Activity Feed API, Agents API, auth API, and 7 more. Tagged areas include Company, AI Agents, Agentic, Developer Platform, and Automation.

The Archastro catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Archastro’s developer surface includes documentation, API reference, getting-started guide, authentication, CLI, sandbox, changelog, and 21 more developer resources.
