Sereact Raises $110 Million Series B to Scale Its Cortex 2.0 Robotic World Model and Expand Into the US

Overview

Sereact, a German startup building artificial-intelligence software for industrial and warehouse robots, has raised a $110 million Series B round led by the venture firm Headline, according to Tech.eu. The company announced the round on April 27, 2026, and said the capital will go toward scaling its latest software model, Cortex 2.0, and opening a first office in the United States, as reported by SiliconANGLE.

The deal places Sereact among the more heavily funded entrants in a wave of companies betting that the hardest part of robotics is no longer the machine but the software that decides what it should do.

What We Know

The round brings Sereact’s total funding to more than $140 million, according to Sereact. Headline led the investment, with participation from Bullhound Capital, Felix Capital, Daphni, Air Street Capital, Creandum, and Point Nine, the company said. The Series B follows a 25 million euro Series A in January 2025 that was led by Creandum, Tech.eu reported.

Sereact was founded in 2021 by Ralf Gulde and Marc Tuscher, both former AI researchers at the University of Stuttgart, according to SiliconANGLE. Gulde serves as chief executive and Tuscher as chief technology officer, per The Next Web.

The company sells software rather than robots. Its products are vision-language-action models that, as The Next Web describes, let robots “perceive their environment, interpret instructions, and execute physical tasks” without being explicitly programmed for each job. “We ship one thing: the model that runs on any robot,” Tuscher said, according to Sereact.

The round funds the rollout of Cortex 2.0, the next generation of that model. Sereact describes the system as augmenting a vision-language-action model with a world model: from the robot’s current state, it “generates a set of candidate future trajectories, runs them against a learned model of physics and object behavior, and scores each one for stability, risk, and efficiency,” according to Sereact. In practical terms, The Next Web notes, “A robot picking a fragile object can, in principle, evaluate whether its planned grip will cause damage before its gripper closes.”

Gulde framed Cortex 2.0 as a move beyond simple picking into tasks where physical contact matters. “It takes Cortex out of the picking bin into work where contact matters - assembly under tension, kitting, placement where every millimetre counts,” he said, according to Tech.eu.

Sereact lists a roster of industrial and logistics customers including BMW, Daimler Truck, PepsiCo, the Dutch e-commerce operator Bol, and Active Ants, according to SiliconANGLE. The company says it has deployed more than 200 systems across Europe, which have completed over a billion real production picks, with roughly one in 53,000 picks requiring remote human help, according to Sereact.

The funding is earmarked in part for US expansion. Sereact said it is opening its first US office in Boston and hiring commercial, application, and engineering staff locally, according to Sereact.

Investors framed the bet in terms of physical AI’s scale. “The physical AI opportunity is one of the largest we’ve seen in a generation and we believe it will rewire global supply chains and manufacturing,” said Trevor Neff of Headline, according to SiliconANGLE. Johan Brenner of Creandum drew a contrast with the rest of the field: “Most AI robotics companies are currently hardware-first. What sets Sereact apart is their software-first, foundational approach which means they have the potential to become the brain of any robot that requires vision and autonomous capabilities,” he said, according to The Next Web.

What We Don’t Know

Sereact did not disclose a valuation for the round. The company has not published independent benchmarks comparing Cortex 2.0’s reliability on the new contact-rich tasks, such as assembly under tension, against its established picking workloads, and the picks-per-intervention figures it cites describe its existing deployments rather than the new capabilities the funding is meant to scale. The timing and staffing scale of the Boston office beyond an initial commercial, application, and engineering team were not detailed.

Analysis

Sereact’s pitch sits at a fault line running through the current robotics boom: whether durable value accrues to the companies building robots or to the companies building the software that controls them. Its software-first posture, selling a model that runs on third-party hardware rather than a proprietary machine, distinguishes it from the humanoid developers that have dominated recent funding headlines. The customer list, weighted toward European automotive and logistics names like BMW, Daimler Truck, and PepsiCo, suggests the company is targeting existing industrial automation rather than the consumer or general-purpose humanoid markets. The move into Boston signals an attempt to compete for US enterprise contracts and talent against a dense field of American robotics-AI startups.
