Portia AI
Open-source framework for building predictable, authenticated AI agents in regulated environments
About Portia AI
Portia AI is an open-source developer framework for building predictable, stateful, and authenticated AI agent workflows. Built around three pillars — predictability, controllability, and authentication — it enables teams to deploy safe, reliable AI agents in regulated industries like finance and healthcare. The SDK generates structured multi-agent plans, manages execution states, authenticates users into external tools (Google, Slack, Zendesk, GitHub, and 1000+ more), and directs LLMs when human input is required. Backed by General Catalyst with 5.1M in funding, Portia combines an open-source Python SDK with a cloud platform offering prebuilt tools with out-of-the-box authentication.
