Spillmark

Spillmark is the agentic Amazon growth platform for Amazon sellers. Run Amazon on Autopilot with AI agents that pull 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. Agents can plan geo holdout tests to measure whether Meta ads really drive Amazon sales. Results show the sales your ads caused as a range. Connections are read-only and your data is never shared. MCP access works with Claude, ChatGPT and Grok when available.

Pricing: Free $0 (1 account, manual dashboard). Standard $49/mo (1 seller account, AI + MCP). Enterprise $199/mo (5 accounts). $30/mo per extra account.
