Aikido Security

Aikido Security is a Ghent, Belgium-based application security company, founded in 2022, that built an all-in-one Application Security Posture Management (ASPM) platform consolidating more than fifteen previously separate scanner categories — SAST, software composition analysis, secrets detection, infrastructure-as-code scanning, container scanning, DAST, and cloud posture management — into a single developer-facing interface. Rather than selling security teams a stack of point tools developers route around, Aikido surfaces findings directly in pull requests and IDEs with auto-generated fixes, aimed at closing the gap between the team that owns the risk and the team that owns the code.

In June 2026, Aikido acquired Root (formerly Slim.AI, the container-security startup behind the open-source Slim Toolkit, which had rebranded to Root in March 2024) for a reported $70-100 million. The acquisition adds Root’s ability to backport security patches onto open-source dependencies at the exact version an organization is already running, without forcing a disruptive version upgrade — directly targeting the "patch now versus break the build" tradeoff that stalls vulnerability remediation in most application security programs.

Aikido reached a $1 billion valuation in roughly three years off a $60 million Series B led by DST Global, with PSG Equity, Notion Capital, and Singular participating — a pace the company and multiple trade outlets describe as the fastest for a European cybersecurity firm. Named customers include the Premier League, Revolut, SoundCloud, and Niantic, putting checkable enterprise logos behind the platform.
