Sereact

Advanced

A German warehouse-robotics AI company that runs picking robots on its own Cortex model.

Sereact was founded in Stuttgart, Germany, in 2021, later adding a Boston office; founders Ralf Gulde and Marc Tuscher both came out of the University of Stuttgart. It builds software for robots in warehouse logistics: its own robot foundation model, Cortex, and a 3D perception system drive robot arms through tasks such as order picking and returns processing, with customers including BMW, Mercedes-Benz, and IKEA, and more than 200 systems deployed. Its typical setups are single-arm picking stations and dual-arm returns-processing stations, and it is also developing a wheeled-base humanoid robot. It closed a €25 million Series A in January 2025; in April 2026 it raised a $110 million Series B led by Headline, which grew to $116 million after Zalando joined, with the funds going toward a model that lets robots predict the consequences of an action before taking it.

ExampleIn an e-commerce warehouse, Sereact's picking workstation uses a robot arm to grab differently shaped items out of a tote and place them into an order box.
