Run your Amazon store on autopilot with AI agents

About

Spillmark measures whether Meta ads caused an Amazon seller's sales. It plans a geo holdout from the seller's own orders, locks the test before it starts, and reports the result with a range. The seller approves every change. Free calculators run on the site and over the public MCP server. Plans start at $19 a month.
