x.ai (Amy and Andrew)
2014 - 2021, 8 years old
AI scheduling assistants Amy and Andrew Ingram that handled meeting coordination over email, one of the first widely deployed autonomous agent products. Not the Elon Musk xAI.
x.ai pioneered the email-based AI agent pattern but spent years relying on a large back office of human trainers to clean up natural language scheduling requests, and never found unit economics that worked at scale against free Calendly-style link tools. Bizzabo acquired the company in June 2021 to fold the scheduling tech into its events platform, then sunset the standalone Amy and Andrew product on October 31, 2021. Mortensen has since written candidly about how the vertical agent thesis arrived a decade too early on the underlying model quality.
