Oneleet

Oneleet, founded in 2022, builds a unified security and compliance platform that combines genuine security controls with regulatory compliance. The product consolidates penetration testing, code security scanning, cloud security posture management, attack surface monitoring, mobile device management and security training into a single integrated system, helping companies work towards SOC 2, ISO 27001, HIPAA, GDPR and PCI compliance while building real security. The company reports that it is the most popular security compliance platform in the Y Combinator community.

Oneleet was founded by former penetration testers whose background includes more than a decade breaking into Fortune 500 systems and government infrastructure. That experience shapes the company's approach: it is rooted in a critique of what the founders describe as the failures of compliance theatre, and it rests on the idea that genuine security and regulatory compliance should work together rather than against each other.

The company has raised $33 million in a Series A round and counts Y Combinator and Dawn Capital among its backers. Its technical domains span offensive security, cloud and application security, endpoint management and security training, with a focus on the cybersecurity and software/SaaS sectors.
