Belgium’s Aikido Security has closed a $60 million Series B round at a valuation of $1 billion, making it the fastest European cybersecurity company ever to achieve the famous unicorn status.
Aikido was founded in 2022 to unify security across the entire software lifecycle. The platform replaces fragmented security tools with a single system that secures software from code to cloud to runtime, with developers automatically detecting, prioritizing, and remediating risks.
The company is growing rapidly and now has customers such as the Premier League, Niantic, Revolut and SoundCloud, with more than 100,000 teams worldwide. Last year, the Zen offer of Aikido was at the Cybersec & Computable Awards on Cybersec Europe voted Best Cybersecurity Innovation Europe in Brussels. In 2024, they were Tech Startup of the Year.
Outdated security tooling
The recent $60 million funding round was led by DST Global, followed by PSG Equity, with participation from Notion Capital and Singular. As a result, Aikido is estimated at one billion dollars, which is also the fastest Belgian unicorn ever. This milestone comes as cybersecurity is under pressure from AI-generated code, autonomous agents, and continuous deployment, while many security systems still rely on manual reviews and workflows for slower development cycles.
Aikido responds to all that. “Most security tooling is still anchored in the past,” suggests Willem Delbare, co-founder and CEO of Aikido. “As construction cycles collapse from months to minutes, security must evolve. It must be continuous, adaptive and autonomous, and secure software as a dynamic system.’
Aikido Infinite: Autonomous Penetratietests
Aikido recently launched Aikido Infinite, continuous autonomous penetration tests that reduce risk with each release by automatically testing applications, confirming issues and fixing them. Aikido Infinite must close the loop between attack and fix.
With this announcement, Aikido also continues to focus on an integrated platform that covers the full attack surface, instead of fragmented point solutions. With sixty million dollars in funding, Aikido positions itself as a solid European counterpart to American security unicorns.
