About OneCLI
OneCLI (YC S26) is an open-source AI teammates platform for teams. Like Grok Bot, but self-hostable, loved by developers. Each employee gets their own sandboxed pro assistant agent, connected to their GitHub, Gmail, Notion, Dropbox, or CRM right from the chat/Slack, while the whole workspace runs under one policy your admins control. Agents never hold real secrets: the credential is injected at the network layer, per request, after the call is authorized. You can't steal what isn't there.
