SO1

SO1 (Segment of One) is a Berlin-based AdTech company that develops AI-powered personalization platforms for retail promotions and advertising. The SO1 engine analyzes individual consumer purchase behavior to generate hyper-personalized promotions, enabling consumer goods manufacturers and retailers to reach customers with precisely targeted offers. SO1's technology operates as a dedicated promotional channel for retail chains, driving measurable sales lift and return on ad spend. The platform leverages advanced machine learning to build detailed product maps and consumer behavior models at the individual level — a true segment of one rather than broad demographic clusters. SO1 partnered with GfK as its exclusive international partner for AI promotion personalization, and has been deployed across major European retail networks.
