Oneleet

Full-coverage cybersecurity platform and roadmap

Overview

Oneleet provides a full-coverage cybersecurity platform that helps companies build, manage, and monitor their cybersecurity program. Its core offering is a roadmap that guides the implementation of a wide range of security activities—such as penetration testing, vulnerability assessments, awareness training, static code scanning, and endpoint monitoring—within a single platform so teams can plan, execute, and track progress. Unlike tools that offer isolated security functions, Oneleet integrates multiple security disciplines into one roadmap and management experience, making it easier for organizations to achieve secure posture and demonstrate trust to partners. A YC-backed startup, Oneleet’s goal is to simplify effective cybersecurity and reduce friction for companies implementing comprehensive security programs.

European RegTech funding jumps 51% to $1.1B as deals over $100M return

European RegTech funding rose 51% year-on-year in 2025, reaching $1.1 billion across 122 deals, up from $724.2 million in 111 transactions the previous year. The rebound was driven by the return of deals over $100 million, which generated $117.2 million after recording zero such transactions in 2024. Average deal size increased to $8.95 million from $6.5 million in 2024. However, both deal volume and total funding remained 55% below 2021 levels, when the sector recorded 269 deals worth $2.4 billion. Oneleet, a security compliance platform, secured one of the year's largest European RegTech deals with a $33 million Series A round led by Dawn Capital. The 2022-founded company uses AI to automate compliance monitoring for enterprises facing complex regulatory obligations.
