Several members of the two-year-old company's founding team helm from Palo Alto Networks, including CEO Joe Lin.
Twenty, a developer of offensive cyber software that leans on automation techniques, has collected $100 million in Series B capital from investors to aid further development work on those tools.
Twenty opened for business in 2024 to build artificial intelligence-enabled systems for U.S. military and intelligence community operators. Several members of its co-founders worked in senior positions at Palo Alto Networks, where Twenty’s CEO Joe Lin was also a vice president.
Accel led the Series B round announced Wednesday, which values Twenty at a touted $1 billion. Friends & Family Capital, Point72 Ventures and Caffeinated Capital also participated. General Catalyst and In-Q-Tel were among Twenty’s early backers.
Twenty designs the tools to pair operators with AI and automation capabilities that still require human judgment. A bulk of the new investment will go toward research-and-development initiatives.
AI models and technology are increasingly becoming core to cyber efforts, including defensive and offensive missions. Anthropic describes its Claude Mythos Preview model as having the ability to both identify software vulnerabilities and exploit them for cyberattacks, a capability federal agencies have keen interest in.
