OpenTag on the record

What they shipped

  • From its YC profile: OpenTag - is an AI coworker that lives in your Slack and Teams. It has full context on your company, so it can answer questions, join calls, and take real work off your team's plate. OpenTag also keeps your company wiki and knowledge base up to date automatically, so your team's knowledge never goes stale or walks out the door. (source)
  • Its own site describes it as: "OpenTag is the model-agnostic AI coworker: eighty models to route to, up to 70% off what a tagged task costs, and never in the business of selling you tokens." (source)

Who is behind it

  • Tony Kam, Founder/CEO: Co-founder and CEO at Open Tag. Previously at Tesla and founded Lilac Labs (S24). Studied EECS at Berkeley. (source)
  • Wilson Nguyen, Founder: Co-founder at OpenTag. Previously founding engineer at Lilac Labs (YC S24). Studied Computer Science at UC Berkeley. (source)
  • Shelden Shi, Founder/CTO: Co-Founder and CTO at OpenTag. Previously founded Lilac Labs (S24). Studied CS and CogSci at UC Berkeley. (source)
