In December 2025, London-based AI workflow automation startup Curvestone AI raised $4 million in a Seed funding round. The round was led by MTech Capital, with participation from Boost Capital Partners, D2 Fund, and Portfolio Ventures.
Founded by CEO Dawid Kotur and COO Sebastian Kotur, Curvestone AI provides a platform designed to bring reliable AI automation to regulated industries like financial services, legal, and insurance.
The company addresses the “accuracy gap” in generative AI by offering a platform that allows enterprises to build agentic workflows with human-in-the-loop controls. Unlike standard chatbots, Curvestone’s technology enables firms to decompose complex tasks—such as mortgage compliance checks or legal document reviews—into auditable steps. This ensures that AI outputs are accurate, verifiable, and compliant with strict industry regulations.
The new capital will be used to accelerate product development, expand its engineering team, and grow its customer base across the UK and Europe.
