SegmentStream is a marketing measurement platform that gives AI agents an attribution, budget-optimization, and incrementality-testing "brain." It consolidates first-party and third-party marketing data in Google BigQuery and applies ML-powered, cross-channel attribution across 20+ ad platforms (Google Ads, Meta, TikTok, LinkedIn, Microsoft, Snapchat, Pinterest, Reddit, Criteo, and more), then recommends budget reallocation via marginal-ROAS analysis and validates impact with geo-holdout incrementality experiments. Every capability is exposed as a tool through a hosted Model Context Protocol (MCP) server, so Claude, ChatGPT, Cursor, and any MCP client can query attribution reports, manage configuration, and run BigQuery SQL over a workspace. Backed by Techstars.
