About the company

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.

Simplify's Take

What believers are saying

  • October 2025's $33 million Dawn Capital Series A extended runway and hiring capacity.
  • Oneleet reported $9 million ARR at Series A, showing real customer willingness to pay.
  • The July 2026 platform update added continuous monitors and multi-framework mapping, deepening lock-in.

What critics are saying

  • Vanta, Drata, Sprinto, Secureframe, and Thoropass crowd Oneleet's 2026 buying decisions.
  • Custom pricing and no self-serve signup slow adoption against faster, cheaper rivals.
  • If audits or monitors fail, one enterprise breach can destroy trust and trigger churn.

What makes Oneleet unique

  • Oneleet bundles SOC 2, ISO 27001, pen testing, and vCISO guidance in one platform.
  • Its control-mapping engine maps one security control across SOC 2, ISO 27001, and HIPAA.
  • Founded by Bryan Onel, a former penetration tester, it sells security credibility, not paperwork.

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.
