Worker.ai, a small business operating system backed by Ratmir Timashev, acquired DeltaGen, a Prague-based voice AI startup. Financial terms were not disclosed. DeltaGen builds real-time voice AI for sales conversations.
Founder and team moves
All three DeltaGen founders are moving to Worker.ai, with René Bystroň becoming co-founder and COO. Michal Studnička and Matúš Ondreička take product and technical roles. The existing team of about 10 people will stay in Prague.
DeltaGen background
DeltaGen previously raised funding from Forward Venture Capital and Techstars. The startup launched Virtual SE in November 2025. That tool gives B2B sales reps answers to technical questions during live calls.
How Worker uses the voice AI
Worker puts a company's plans, responsibilities, numbers, and processes in one place. DeltaGen's technology captures decisions, commitments, and next steps during conversations. Worker turns those items into assigned tasks and asks employees to approve key steps.
Worker plans to grow its Prague product and engineering team. It is also introducing its operating system for small firms. The acquired voice AI will support that system.
