Curvestone AI is Bringing Reliable AI Automation to Regulated Industries

Curvestone AI, the platform for regulated firms to automate complex tasks with code‑simple AI flows, led by Dawid Kotur and Sebastian Kotur, has secured $4 million in seed funding, led by MTech Capital with participation from Boost Capital Partners, D2 Fund, and Portfolio Ventures. The funding round will advance Curvestone AI’s mission to make AI automation truly dependable for financial services, legal, and insurance teams.

Most AI tools excel at isolated tasks but face steep accuracy drops in multi-step, real-world workflows, where a single 98% step can fall to 30–40% when chained across a dozen operations. Curvestone AI addresses this “compound error problem,” ensuring consistent accuracy throughout document-heavy, regulated processes. Before external funding, the company achieved profitability, 7× revenue growth over 12 months, and now processes billions of tokens quarterly across financial and legal workflows.

Curvestone AI was founded by brothers Dawid and Sebastian Kotur, who previously led AI automation programs at PwC, Metro Bank, and GKN. Observing the limitations of traditional GenAI in regulated environments, they built Curvestone to deliver scalable accuracy, control, and auditability.

The platform now serves firms across legal, mortgage, and wealth management sectors, including Stephenson Harwood, Browne Jacobson, Walker Morris, and Pivotal Growth. Early deployments demonstrate significant impact:

• Walker Morris reduced service agreement reviews from 4 hours to 15 minutes.

• Stephenson Harwood implemented a multistep DORA-aligned compliance workflow.

• Pivotal Growth expanded from reviewing ~10% of mortgage cases to 100%, achieving consistent, auditable outputs across 20 advice teams.

Dawid Kotur notes that financial services demand precision, and AI that reliably delivers accuracy fundamentally changes operational efficiency and risk management.

Kevin McLoughlin, Partner at MTech Capital and incoming board member at Curvestone AI, highlighted the company’s success in automating complex workflows with high accuracy, a critical requirement in regulated industries. He also noted that the founders achieved profitability without external funding, and early traction indicates strong demand across financial services, legal, and insurance sectors.

The funding will accelerate Curvestone AI’s product development and go-to-market expansion, enabling growth of its library of proven workflows and deeper integrations with CRMs, document management systems, and core business platforms. It also advances the long-term vision of creating a reliable automation layer for agentic AI in regulated industries.
