About us

So1 is Google Adwords for retail.

We have built and are expanding a revolutionary cross-retailer promotion platform based on cutting-edge algorithms and a seamless online integration with traditional offline retailers. On our platform we allow both brands and retailers to target consumers truly individually and in real-time with the most efficient discounts and promotions.

Our models infer, predict, explain and measure the behavior of shoppers. Our algorithms optimize for econometric goals adjusted for long-term customer satisfaction and engagement.

The So1 Engine learns from billions of consumer transactions and derives the right impulse at the right time to induce a change in customers’ behavior.

We have partnered with leading retailers and are successfully marketing our unique platform and business model to the world’s largest brands. So1 has been backed by high-profile investors Target Partners and Shortcut Ventures with 8-figure investments.
