Product overview

SegmentStream is an AI-powered marketing measurement platform headquartered in London, United Kingdom, founded in 2018. It uses machine learning to score each website visit based on its probability of leading to a conversion, even when cookies or tracking fail to connect the visit to a later sale. This approach, called ML Visit Scoring, assigns attribution credit based on the incremental contribution of each marketing touchpoint rather than relying on traditional last-click or cookie-based tracking. SegmentStream also provides cross-channel reporting with automated ROAS and CPA metrics, AI-driven budget optimization recommendations, and geo-based incrementality tests to measure the true lift of paid media. The platform targets advertisers spending at least $50,000 per month on media and counts L'Oréal and KitchenAid among its customers. Pricing is custom and requires a sales consultation. The company is backed by R136 Ventures and participated in the TechStars accelerator. KEY FEATURES: - ML-based visit scoring for cookieless, incremental attribution - Cross-channel marketing reporting with automated ROAS and CPA metrics - AI-driven budget optimization across paid channels - Geo-based incrementality testing for measuring true media lift - Integrations with Google Ads, Meta, LinkedIn, and TikTok
