AI cyber warfare startup Twenty raises $100M at $1B valuation

Twenty Inc., a startup that develops cyber warfare software for the U.S. military and intelligence community, has raised $100 million in funding.

Accel led the Series B investment. Twenty stated in its announcement of the deal today that Friends & Family Capital, Point72 Ventures and Caffeinated Capital participated as well. The company is now valued at $1 billion.

Twenty was launched in 2024 by a group of former public sector cybersecurity experts. Several of its co-founders also held senior roles at Palo Alto Networks Inc. Twenty Chief Executive Joe Lin was a vice president of product management at the cybersecurity giant.

Twenty’s cyber warfare software uses artificial intelligence to reduce manual work for users. According to the company, some of the tasks that its systems automate can take humans weeks to complete. At the same time, Twenty says the systems “keep human judgment at the center” by facilitating manual evaluations.
