Arcade
Tool-calling infrastructure for agents with OAuth built in, so an agent can act on a user account without you building the auth flow.
Highlights
- AI tool-calling platform with built-in OAuth, observability, and developer experience for agent builders
- Founded in 2024 by Alex Salazar (ex-Okta), Sam Partee, and Atul Tulshibagwale
- Approximately $12M+ seed; backed by Laude Ventures, Madrona, and others
- Handles the OAuth and auth dance for agents calling third-party tools (Gmail, Slack, GitHub, etc.)
- Pre-built toolkits for popular SaaS integrations plus custom tool deployment
- TypeScript and Python SDKs; works with major LLM providers and agent frameworks
- Used by teams building production AI agents that need to do more than chat

About Arcade
What it is
Arcade provides the layer between an agent and the tools it calls: a catalogue of integrations, built-in OAuth so an agent can act on a user's behalf in their own accounts, plus observability over what was called. It was founded by former Okta engineers.
Why it's different
Authentication is the correct thing to have specialised in, and the founders' background shows. Every agent framework demonstrates tool calling against an API key in an environment variable; the moment you need an agent to act in your *user's* Google account you are building OAuth flows, token refresh and per-user credential storage, which is weeks of security-sensitive work that has nothing to do with your product. Arcade packages exactly that. The trade is the significant one: a third party holds tokens to your users' accounts, so its security posture becomes yours, and that is a diligence question rather than a pricing one.
How people use it
It is used by teams building agents that act in end users' own accounts — reading a customer's calendar, filing to their Drive, sending as them. The observability matters more than it first appears, because when an agent does something unexpected in someone's account, a record of which tool was called with what is the difference between an explanation and an apology.
