Koi Raises $48M to Reinvent Endpoint Security for the Modern Software Stack
Koi, an endpoint security startup founded by Israeli Military Intelligence veterans, raised $48 million across seed and Series A rounds to secure the modern software layer including extensions, AI models, containers, and code packages. The company was born from a white-hat hacking experiment in which founders created a malicious VSCode theme extension that compromised over 300 organizations within a week. Backed by Battery Ventures, Team8, Picture Capital, and NFX, Koi has already scaled to protect over 500,000 endpoints globally and exceeded seven-figure revenues in eight months.
