Marble raises $3.75m to build AI coworkers - Seedcamp

Every company wants AI to take on more of their work. The hard part is figuring out what that work actually is.
Humans are notoriously bad narrators of our own work. Ask a colleague how they use a spreadsheet, and you’ll probably get a significantly pared-back explanation, rather than an accurate account of the edge cases, missing information and delays that crop up along the way.
As a result, many companies end up pursuing costly AI transformation projects, without a clear sense of how work actually gets done in their companies.
Marble Cognition is working to change this, with AI that learns how work actually gets done inside a company, then deploys AI coworkers to take it over. Today, we’re proud to lead their $3.75M pre-seed round alongside Heartcore.
Every company runs on processes no one has ever written done. In fact, Founder Felix Rösner estimates that 90% of the core processes of the companies he’s worked with live solely in inboxes and in people’s heads. The technology to automate these processes exists. What’s missing is an exact picture of how this work gets done.
Marble builds that picture. It observes how teams work, turning every process into a structured map that AI can read like code. It then builds Marble Coworkers that run the process end to end in the tools teams already use, with humans in the loop where judgement matters. Traditional automation bends a standard product to fit a company’s processes. Marble productises the understanding of the process itself.
Privacy is of utmost importance to Marble’s mission. Everything Marble captures is anonymised before any person or AI model sees it, even in the customer’s own cloud. Marble’s desktop app records the screen, clicks and keystrokes in the business apps people use at work, never private apps, private tabs or anything outside working hours. Employees can pause it at any time and data is only analysed in aggregate, not based on individuals.
Early customers have seen remarkable results. At a PE-owned US financial services company, a Marble Coworker cut handling time per case by 90%. In the first month, the team handled 50% more cases without new hires. In both cases, the AI was taught by observing, rather than through documentation.
“Every company we talk to wants AI to take over real work. But nobody can tell the AI how that work is actually done,” said Felix Rösner, co-founder of Marble. “So we solve that first. Our Coworkers watch how the work happens before they take it over. They do it the way your best people do.”
Reshma Sohoni, Partner at Seedcamp, said: “Seedcamp has a long tradition of backing founders who change how we work, from UiPath and Synthesia to Marble today. Most companies want to automate more, but the hard part has always been mapping out how the work gets done. Marble fills that gap, giving companies vital context for AI transformations that could define their future. We’re proud to back them from the start.”
The funding will be used to scale inference, grow the engineering team in Munich and launch in the US.
