About

Spillmark is a web-based marketing analytics and experimentation product for Amazon sellers using Meta ads. It combines data from Amazon Seller Central, Amazon Ads, Meta, and optionally Shopify through account connections or report imports to analyze sales, costs, fees, ad spend, and channel profit. Sellers can design and run geographic holdout tests that pause Meta ads in selected regions, then compare Amazon sales to estimate advertising's incremental effect. Results include uncertainty ranges and explanations of the calculations, alongside dashboards, alerts, and records of test designs. Connected-account access is read-only; the product does not change campaigns without seller approval. Spillmark also provides an MCP server and REST API for assistants and scripts. Brand-level measurement and recommendations are in private beta. Starter includes one active holdout test and alerts; Growth includes unlimited tests, live account connections when available, and branded Amazon PPC tests.

About

WorkMagic helps omnichannel brands measure the true impact of their marketing by combining incrementality testing, multi-touch attribution, and MMM into one unified platform. Its automated geo-based incrementality tests reveal what spend actually drives incremental sales across DTC, Amazon, retail, and wholesale. Instead of relying on guesswork or over-attribution from ad platforms, WorkMagic calibrates attribution models using real experimental results for maximum accuracy. Brands get a clearer view of performance, smarter budget allocation, and higher iROAS. Onboarding takes minutes, thanks to seamless integrations with Shopify, marketing channels, and marketplaces. With WorkMagic, teams finally understand what truly works—and what doesn’t—and can scale efficiently with confidence.
