Pistachio offers a fully automated system that delivers personalized cyberattack simulations and training through tools like email, Microsoft Teams, and Slack, requiring no manual oversight. With clients in 16 countries and over 600 organizations using the platform, the funding will go toward scaling operations and product development aimed at addressing human error in cybersecurity. Walter Ventures’ Atanas Mukov and Angel Invest’s Remo Mahler will join the company’s board as part of the round.

As the world’s first fully automated cybersecurity awareness platform requiring no manual oversight, Pistachio empowers businesses to reduce human risk through AI-driven, personalized security training and attack simulations. The platform sends realistic, personalized cyberattack simulations and security scenarios directly to employees’ inboxes, Microsoft Teams, or Slack. It runs autonomously in the background, helping employees recognize and respond to threats in real time, through seamless, in-context training.

With a presence in 16 countries, users in 99 countries, and more than 600 companies using the platform (including Scotland’s University of St Andrews and Europe’s largest Managing General Underwriters, The Riskpoint Group), the company will use the latest capital injection to bring outdated enterprise cybersecurity training into the AI era and set the gold standard for security culture among global businesses. By analyzing user behavior and learning patterns, the platform ensures that every employee receives relevant, engaging, and practical security education, significantly reducing the risk of costly security breaches ($4.88 million per breach on average), 95% of which were attributed to human error in 2024.
