What OneCLI does

OneCLI is an open source agent harness for teams. 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.

What is your company going to make? Please describe your product and what it does or will do.

OneCLI is an open source agent harness for companies. We give every employee their own AI teammate: a sandboxed assistant that connects to their Github, Gmail, Notion, Dropbox, or CRM, right from chat or Slack. Admins control everything with one company-wide policy. Agents never hold real secrets; credentials are injected, per-request, after authorization - so if a machine is compromised, there's nothing to steal.

Where do you live now, and where would the company be based after YC?

San Francisco, CA, USA. We'd stay based here after YC.

Explain your decision regarding location.

We're building OneCLI in San Francisco because it's the best place to ship a security-focused B2B AI product, surrounded by early adopters and technical users.
