A general AI knows about investors. It doesn't know what they did this week.

Ask a general assistant who invests in seed climate hardware and you'll get a list of well-known names, some stale, none sourced.

Connect Yellowtail and the same question returns investors who have shown intent recently, each with the signal, the date and a link, plus whether you have a warm way in.

Your data, your rules.

  • Sign in, no shared keys

    Access uses your Yellowtail login and respects your workspace permissions.

  • Read first, act with approval

    Tools that change anything, like adding to a list, ask before they run.

  • Your lists stay private

    The AI only sees what your account can see, and nothing is shared with other customers.
