Twenty announced that it has raised a $100 million Series B funding round at a $1 billion valuation. The round was led by Accel, with participation from Friends & Family Capital, Point72 Ventures, and Caffeinated Capital. The new funding brings Twenty’s total funding to $138 million.
Founded in 2024, Twenty describes itself as America’s first venture-backed cyber warfare startup. The company is focused on industrializing offensive cyber warfare capabilities for the United States and its allies.
Twenty builds AI-enabled, end-to-end systems for the U.S. military and Intelligence Community. The company said its systems are designed to give warfighters the speed and scale needed to deter and defeat adversaries in cyberspace.
The company said its systems are designed to keep human judgment at the center by pairing advanced AI and automation with rigorous evaluation, controlled deployment, and mission alignment.
The Series B follows increased demand for offensive cyber capabilities that can be developed at commercial speed. Twenty said the funding will be invested directly into research and engineering.
Twenty’s prior rounds were led by Caffeinated Capital and Tim Junio, Co-Founder and CEO of Expanse, which was acquired by Palo Alto Networks for $1.25 billion in 2020. Early investors also included General Catalyst and In-Q-Tel.
The company said the new funding will support its mission to build the industrial base for American cyber power and strengthen cyber capabilities for the United States and allied partners.
KEY QUOTES:
“America is under sustained cyber attack, and our adversaries have learned—correctly—that those attacks rarely carry consequences. Twenty exists to change that. We are building the industrial base for American cyber power: the AI-enabled capabilities our warfighters need to disrupt threats at their origin. This round is extraordinary validation from some of the world’s foremost investors, and we are pouring this funding directly into research and engineering.”
Joe Lin, Co-Founder and CEO of Twenty
“As a country, we need to invest more into cyber capabilities to protect our national security. We have under invested over an extended period. Investing into the best cyber capabilities will create one of the strongest and most cost effective deterrents we can build. Accel is proud to lead this round and help set the standard for investing in the capabilities the country needs most. Twenty is the clear leader in this market: the team is unmatched, the mission is urgent and timely, and the company has reached operational relevance at a pace rarely seen in defense technology.”
Jonathan Turner, Partner at Accel
“For fifteen years we have backed founders who challenge the limits of what is possible. Twenty’s speed from founding to operational relevance is in a class of its own. The company has moved with commercial urgency in one of the government’s most sensitive and consequential mission areas, which is extraordinarily difficult to do. Having first backed Joe and team nearly a decade ago, we are proud to partner with them once again as Twenty builds capabilities that are critical to America’s security.”
Colin Anderson, Founding Partner at Friends & Family Capital and former CFO at Palantir
