About Curvestone

Curvestone is building the AI workflow layer for complex, high‑stakes processes , from legal contract reviews and compliance checks to financial audits and insurance claims.

Regulated services are still dominated by manual, siloed workflows that are hard to scale without risk. Our platform changes that. Curvestone AI automates multi‑step, document‑heavy processes with the precision, auditability, and security demanded by regulated industries , unlocking speed and accuracy that were previously out of reach.

We partner with compliance officers, legal ops leaders, and financial services innovators who rely on us as critical infrastructure. For them, we are not a “nice‑to‑have” experiment. We are business‑critical.

We are a high‑growth company headquartered in Holborn, London. Our team brings together expertise in AI, automation, and enterprise transformation, united by a mission to reinvent how regulated industries work.
