Riot raises $30m to combat AI-driven cyber threats with employee security solutions

Riot, a cybersecurity company focused on employee security solutions, has raised $30m in a Series B funding round.

The round was led by Left Lane Capital, with participation from existing investors Y Combinator, Base10, and FundersClub.

The funding comes as Riot experiences rapid growth, surpassing $10m in annual revenue in 2024. The company has seen triple-digit expansion.

Founded five years ago, Riot provides real-time employee cybersecurity monitoring, helping businesses strengthen their security posture. Its platform detects vulnerabilities such as weak passwords and unsafe file permissions, guiding employees to resolve them through interactive coaching. Riot’s cyber coach, Albert, offers practical security insights via workplace tools like Slack, Microsoft Teams, Google Chat, and email. The company serves over 1,500 organisations, including Mistral AI, Modern Treasury, L’Occitane, Deel, and Intercom.

With the new funding, Riot aims to accelerate international expansion, double its workforce, and introduce new security features. Plans include launching an aggregated security dashboard with enhanced protections against data breaches, infostealers, and social engineering attacks. The company will also expand its awareness training programme and enhance attack simulations.
