AI coworker for Slack and Teams, keeps your knowledge updated

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

OpenTag is an AI coworker that lives inside your company's Slack and Teams. It has full context on your company so it can answer questions, join calls, and actually take tasks off your plate. We also keep your company wiki and knowledge base up to date without manual effort. Teams don't lose critical knowledge when people leave or stop documenting.

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

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

Explain your decision regarding location.

San Francisco is where our team lives and where most of our current and potential customers are based. It's the best place for early access to other B2B teams adopting new software.
