Rethinking marketing measurement from the ground up

We founded SegmentStream with a clear conviction: marketing measurement needs a fundamental reset.

Our story

In a world of fragmented, cross-device customer journeys and growing privacy restrictions, traditional attribution models have become totally unreliable.

That’s why in 2018 we set out to reinvent measurement for the modern era — combining AI, incrementality, and marketing mix optimization to give marketers the clarity and confidence they need to drive efficient, scalable growth.

Headquartered in London, UK, SegmentStream is now trusted by more than 100 leading customers across the globe and is fortunate to be VC-backed by one of the best investors in the industry — R136, one of the world’s leading startup accelerators — TechStars, as well as some biggest names in the B2B SaaS world, including the founders of Pipedrive, Dynamic Yield, and other great companies.

SegmentStream is proud to be an official partner of Google Cloud, Google Marketing Platform and Meta Business.
