What SegmentStream does
SegmentStream is a London-based SaaS company founded in 2018 that operates an AI-powered marketing measurement and attribution platform for enterprise marketing teams and agencies managing significant paid media budgets. The platform unifies cross-channel attribution, predictive attribution, marginal analytics, incrementality testing via geo holdouts, automated budget allocation, and server-side conversion tracking into a single measurement engine built on Google BigQuery infrastructure. Its distinctive technical approach combines deterministic identity stitching across devices and CRMs, ML-powered conversion projection that fills the click-time attribution gap, LLM-based classification of free-text survey responses, and reinforced learning on diminishing returns curves, all exposed through an AI Skills layer accessible to Claude, Cursor, ChatGPT, and Gemini via the Model Context Protocol (MCP).
The company monetizes through annual SaaS subscriptions priced via custom quote-based enterprise agreements, delivered through a hybrid enterprise sales-led motion (demo requests, custom legal terms) and a self-serve product-led growth path targeting AI-native technical marketers via MCP. Named customers span recognizable brands such as SimpliSafe, Synthesia, Eneco, Raylo, DERTOUR, Florsheim, and Ribble Cycles, alongside an agency channel claiming $100M+ in managed ad spend. SegmentStream integrates with 16+ ad platforms (Google, Meta, TikTok, LinkedIn, Microsoft, X, Pinterest, Snapchat) and data sources including GA4, BigQuery, HubSpot, Salesforce, and Heap.
SegmentStream Ltd is privately held and incorporated in England and Wales (company number 11472676), with disclosed funding totaling $2.72M across two rounds: a $20,000 pre-seed via Techstars and SAP.iO in September 2018 and a $2.7M seed led by R136 Ventures in February 2022. The company is led by Founder/CEO and measurement methodology author Constantine Yurevich, Co-founder/CPO Oleg Katryshev, and Founder/CRO Pavel Petrinich, with a team of 11-50 employees headquartered at 66 Paul Street, London, EC2A 4NA.
