Why connect Amplitude to Claude?

Amplitude can tell you who retained. It can't tell you what each of those users cost, because spend lives in the ad platforms. Through Lemonado, Claude reads both: it lines up first-touch campaigns with week 4 retention and cost, then builds an artifact the growth and product teams can both use.

  • All your Amplitude data

    Events and event properties, ready to ask about.

  • Always today's numbers

    Cohorts and their sizes over time, synced from Amplitude automatically, so answers use today's numbers.

  • Connect all your tools

    Questions like "Which campaigns keep users?" use Amplitude and Mixpanel, PostHog at once.

Good to know

  • Custom connectors work on Claude Free, Pro, Max, Team and Enterprise. Free accounts can add one.
  • On Team and Enterprise, an owner adds the connector first under Organization settings → Connectors → Add → Custom → Web. Members then connect their own accounts.
  • Remote connectors belong to your Claude account, so the same connection shows up in Claude Desktop and Cowork. Requests come from Anthropic's cloud, not your computer.

What can Claude do with Amplitude?

For signups in September, show week 4 retention and cost per retained user by first-touch campaign, as an artifact.

Done. The LinkedIn webinar campaign costs $131 per retained user, a Google brand campaign $48, a Meta lookalike $127 because few stay. The artifact sorts all 23 campaigns.
