Buildbox on the record

What they shipped

  • From its YC profile: Buildbox helps product teams improve the human-agent experience. We analyze user intent, agent behavior, and outcomes to find where users get stuck or lose trust, then turn those findings into ranked, reproducible issues. (source)
  • Its own site describes it as: "An agent can pass an eval and still leave users stuck. Buildbox finds the breakdowns behind failed journeys and ranks them by business impact. Book a demo." (source)
