What SegmentStream is
SegmentStream is a marketing measurement engine for cross-channel attribution, incrementality experiments, marginal analytics, budget allocation, and AI-assisted analysis. Its listed methods include identity graph, predictive attribution, self-reported reattribution, CRM funnel attribution, and server-side conversion tracking. Integrations include analytics, advertising, CRM, commerce, and data platforms such as Google Analytics 4, Adobe Analytics, Heap, Amplitude, Google Ads, Meta Ads, TikTok Ads, Salesforce, HubSpot, Shopify, BigQuery, Snowflake, and Databricks. Customers can connect Claude, Cursor, and other compatible AI clients through MCP using their own AI subscription. SegmentStream says it can build connectors for platforms with an API and import data through Google Sheets, a warehouse, or webhooks. Storage can use a customer BigQuery project or an isolated hosted Google Cloud dataset in a selected US or EU region. The company says it encrypts data in transit and at rest and does not use customer marketing data, prompts, or interaction logs to train general-purpose AI models. Price is scoped after discovery based on channels, data volume, and expert time; SegmentStream does not sign BAAs.
