Worker.ai, a company operating system for small businesses backed by Veeam founder Ratmir Timashev, has acquired DeltaGen, a Prague-based startup that builds real-time voice AI. The financial terms of the deal were not disclosed.
All three of DeltaGen’s founders are moving to Worker. René Bystroň joins as co-founder and COO, Michal Studnička will work on product, and Matúš Ondreička takes over technical development. DeltaGen’s team of around 10 people will stay in Prague, and Worker plans to grow its product and engineering team in the city, one of the most active startup hubs in the region.
DeltaGen previously received investment from Dutch firm Forward Venture Capital and from Techstars. In November 2025, the startup launched Virtual SE, a tool that gives B2B sales reps answers to technical questions while they are on live calls with clients.
The acquisition started with a personal connection. Worker co-founder and CEO John Roberts knew DeltaGen’s technology from his previous job at a cybersecurity company, and when Worker needed voice AI, he went back to the team he had already worked with.
How they work (together)?
Worker puts a company’s plan, responsibilities, key numbers and processes in one place, where employees and AI workers share the day-to-day work. Teams can hand off recurring tasks such as preparing updates or following up on commitments, while decisions about the business stay with people.
DeltaGen’s technology listens to conversations as they happen and picks out decisions, commitments and next steps. Worker then turns those into assigned tasks. If a team agrees to send a proposal once pricing is approved, for example, an AI worker writes the draft and asks for approval, and the responsible employee signs off on the pricing and sends it.
“Building Veeam showed me the opportunity to bring powerful technology to businesses of all sizes,” said Timashev.
“AI can now give small businesses more capacity without asking already stretched owners to work longer days. Worker is my bet on that shift.”
For Bystroň, the problem is a familiar one from his own family.
“My dad ran a small construction firm. He kept working harder, but the business wasn’t always growing. The internet was supposed to make running a business easier. For him, it added more demands to a day that was already full. AI will have failed people like my dad if all it does is give them more work to keep up with. We’re building Worker so they can grow a business and still come home with time and energy for the people they love.”
