Description

Spillmark is an online analytics and experimentation tool designed specifically for Amazon sellers utilizing Meta ads. This platform integrates data from Amazon Seller Central, Amazon Ads, Meta, and optionally Shopify, allowing users to assess their sales, expenses, fees, advertising costs, and overall channel profitability through various connections and report imports. Sellers have the capability to create and execute geographic holdout tests, which involve pausing Meta ads in designated areas to compare Amazon sales and evaluate the incremental impact of their advertising efforts. The findings are presented with uncertainty ranges and detailed explanations of the methodologies employed, complemented by dashboards, notifications, and documentation of test designs. Access to connected accounts is strictly read-only, ensuring that the product does not modify any campaigns without the seller's consent. Additionally, Spillmark offers an MCP server and REST API for integration with assistants and scripts, enhancing its usability. Currently, brand-level measurement and tailored recommendations are in a private beta phase. The platform's Starter package allows for one active holdout test and provides alerts, while the Growth package offers unlimited tests, live account connections when applicable, and customized Amazon PPC tests, catering to the evolving needs of sellers as they scale their operations. Through innovative features and user-friendly design, Spillmark aims to enhance the marketing strategies of Amazon sellers.

Description

WorkMagic delivers a triangulated measurement system that enables brands to accurately quantify the incremental lift of every marketing channel. Using automated geo incrementality testing, it creates test and control groups that show the real, causal impact of campaigns—without manual setup or technical overhead. The platform then refines attribution models and MMM using these results, giving brands a precise and trustworthy view of ROI. WorkMagic also measures halo effects across Amazon, retail, and wholesale, helping brands see the full spectrum of influence beyond just DTC. With a 10-minute integration and guided onboarding, companies can launch their first incrementality test within a week. Actionable insights reveal how much to spend daily on each channel, which campaigns deserve more budget, and when diminishing returns kick in. Brands using WorkMagic consistently see improvements in ROAS, MER, and CAC. It’s the measurement system built for modern paid media complexity—and for brands seeking profitable, data-backed growth.
