Spillmark

Spillmark is the agentic Amazon growth platform for Amazon sellers. AI agents pull your Seller Central, Amazon Ads, Meta and Shopify data, run tests, and flag problems as they happen. You review the results and approve every move. Nothing changes in your ad accounts without your approval. The free profit dashboard shows profit by channel after Amazon fees, product costs and ad spend, with the math behind every number. To find out whether Meta ads really drive Amazon sales, agents plan a geo holdout test where Meta pauses in a few US states while ads stay on everywhere else. Results show the sales your ads caused as a range, locked before the test starts. Free dashboard, Standard $49/mo, Enterprise $199/mo.
