River for SaaS Founders & Operators

Connect your metrics, track ARR and churn, prep the board, and draft the investor update. One workspace wired to your Stripe and Mixpanel.

The status quo

What slows saas founders & operators down today

  • Metrics split across 6 toolsStripe, Mixpanel, Baremetrics, Amplitude, and a spreadsheet you trust more than any of them.
  • No single ARR source of truthFinance, sales, and the board all work from different numbers.
  • Churn analysis stays on the backlogEvery month you plan to dig into cohorts. Every month other work wins.
  • Board prep is a data fire drillThree days before the board meeting, you pull data from five tools to explain one chart.
  • Investor updates go dark for monthsGood months you mean to send one. Bad months you do not want to. Then six months pass.
