We’re excited to share that Curvestone AI has raised $4 million in seed funding, led by MTech Capital with participation from Boost Capital Partners, D2 Fund, and Portfolio Ventures. The round will accelerate our mission to make AI automation genuinely dependable for financial services, legal, and insurance teams.
Most AI tools perform well on isolated tasks — but struggle in real-world, multi-step workflows. A single step at 98% accuracy can fall to 30–40% when chained across a dozen operations. Curvestone solves this “compound error problem,” enabling consistent accuracy from start to finish in document-heavy, regulated processes.
Before taking on external capital, Curvestone reached profitability, 7× revenue growth over 12 months, and now processes billions of tokens quarterly across financial and legal workflows.
Powering dependable automation for compliance and operations teams
Curvestone was founded by brothers Dawid and Sebastian Kotur, who previously led AI automation programmes at PwC, Metro Bank, and GKN. After seeing first-hand how traditional GenAI fell short in regulated environments, they built Curvestone to deliver accuracy, control, and auditability at scale.
Today the platform supports firms across legal, mortgage, and wealth management, including Stephenson Harwood, Browne Jacobson, Walker Morris, and Pivotal Growth. Early deployments show meaningful impact:
- Walker Morris cut service agreement reviews from 4 hours to 15 minutes
- Stephenson Harwood built a multistep DORA-aligned compliance workflow
- Pivotal Growth is moving from spot-checking ~10% of cases to reviewing 100% of mortgage files, with consistent, auditable outputs across its 20 advice teams
As CEO Dawid Kotur explains:
“The financial services industry runs on precision, and approximation is a deal breaker. You can review everything and go broke, or cut corners and hope for the best. AI that actually works changes that equation.”
Backing from experienced investors
Kevin McLoughlin, Partner at MTech Capital, who is joining Curvestone’s board, said:
“Curvestone is solving the hard technical problem of automating complex workflows while achieving high accuracy — and accuracy is paramount in regulated industries. We were also impressed that the founders bootstrapped to profitability before taking any outside funding. Their early traction shows real demand across financial services, legal, and insurance.”
What comes next
The funding will accelerate product development and go-to-market expansion, helping us grow our library of proven workflows and deepen integrations with CRMs, document management systems, and core line-of-business platforms. It also supports our long-term vision of building the dependable automation layer required for agentic AI in regulated sectors.
Our focus remains the same: AI that teams can trust with the processes that matter most.
