Sereact

Sereact GmbH is a German robotics software company that develops embodied AI for industrial and warehouse robots. Its core product is Cortex, a vision-language-action (VLA) foundation model marketed as a "robotic brain" that interprets natural-language instructions and translates them into physical actions, allowing robots to handle tasks and objects they were not explicitly programmed for. The software is hardware-agnostic and runs on single-arm and dual-arm picking cells, fixed cells, mobile manipulators and humanoid platforms from multiple suppliers.

The product portfolio spans Sereact Pick & Place (autonomous picking and placing across large SKU ranges), Robotic Putwall automation for batch picking and returns sortation, returns inspection and handling, humanoid applications, and Sereact Lens, an in-house optics and AI vision layer for real-time inventory counting, damage and anomaly detection and misplacement tracking. A Sereact Platform layer aggregates robot and Lens data into a unified operational hub with analytics, smart notifications, retrieval-augmented natural-language search over operational history, and agentic chat, and integrates with existing warehouse management systems.

The latest model generation, Cortex 2.0, augments the VLA model with a world model: from the current state it generates candidate future trajectories, evaluates them against a learned model of physics and object behavior, and scores each for stability, risk and efficiency before committing, updating the rollout as the scene changes. Planning takes place in visual latent space, which the company says allows transfer across robot embodiments, and planning compute is tunable per task. Sereact positions this predictive approach against competitors that rely more heavily on end-to-end VLA models.

Founding story

Ralf Gulde and Marc Tuscher, both previously AI researchers at the University of Stuttgart, founded the company in 2021 to close the gap between AI models and physical execution by robots. Gulde serves as CEO and Tuscher as CTO.

Business model

Sereact sells software rather than robots or services: a single model that runs on third-party robot hardware, deployed into customer fulfillment and manufacturing operations and integrated with existing warehouse infrastructure and WMS systems. The company states it ships one product, the model, and describes hardware as commoditizing.

Traction

The company reports more than 200 (site: 300+) live systems, over 1 billion (site: 2B+) real production picks, 50+ deployments across five continents, roughly one remote human intervention per 53,000 picks, pick success above 99% (98% first-attempt accuracy cited elsewhere), typical throughput of 300-450+ units per hour with peaks above 600-650 UPH, and one robot replacing 3 to 4.5 full-time equivalents depending on shift pattern.

Latest developments

In April 2026 Sereact announced a $110 million Series B led by Headline, with Bullhound Capital, Daphni and Felix Capital as new investors and returning backers Air Street Capital, Creandum and Point Nine. The proceeds fund the scaling of Cortex 2.0, which adds a world model for predictive planning, and entry into the US market with a first office in Boston. The company declined to disclose its valuation.
