Marble raises $3.75M to build AI coworkers that learn by watching

Marble Cognition, an AI startup co-founded in late 2025 by Felix Rösner and Christophe Schmit, has secured $3.75 million in pre-seed funding to develop AI-powered technology aimed at helping businesses identify and automate their internal processes. The round was led by Heartcore and Seedcamp, with additional investments from notable angel investors such as a Datadog board member, a Personio founder, and executives from McKinsey, Mistral AI, and Lovable.

Marble's platform employs AI agents, called "Marble Coworkers," which observe employees' daily tasks through a desktop application, capturing screen activity, clicks, and keystrokes. This data is then anonymised and aggregated to create structured process maps that AI systems can understand. Unlike traditional AI, Marble Coworkers replicate the actions of top-performing employees, allowing for seamless integration within existing organisational tools without requiring knowledge of complex workflows.

The company highlights that around 90% of core business processes remain undocumented, creating significant challenges for AI-driven automation. McKinsey estimates that existing technologies could theoretically automate 57% of working hours in the US. By converting these processes into structured maps, Marble aims to bridge this gap and enable companies to effectively implement AI solutions.

Marble's technology is already in use at several organisations, including EGYM, Mutares, Enam, as well as technology firms and private equity-backed businesses. The newly raised funds will be allocated towards scaling Marble's inference capabilities, expanding its engineering team in Munich, and preparing for the launch of its platform in the US market.
