Why your number moved, answered in the first line.
Every likely cause checked against your real data.
How it works.
Name a number that dropped or jumped. River confirms the move, splits it until one slice stands out, lines it up with what changed that week, and reproduces the break in a real browser.
Name the number
Sign-ups, conversion, revenue or churn, and roughly when it moved; River can guess from your dashboards.
River tests every suspect
Tracking breaks, holidays, big customers, releases, pricing and site edits, ad spend and outages.

A few things to know.
Will River change anything while it digs?
River only reads while it investigates. Filing a fix or posting the readout asks you once first.
What if it’s just a tracking glitch?
River checks that first: a broken tracker, a changed definition, a holiday or one big customer get ruled out before it hunts further.
What does it cost?
It uses your plan’s AI credit, like everything else in River. It works from the dashboards and reports your team already has.
