Twenty Hits Unicorn Status With $100M Cyber Warfare Round

Twenty, the startup that bills itself as America's first VC-backed cyber warfare company, raised $100 million in Series B funding at a $1 billion valuation. Accel led the round. Friends & Family Capital, Point72 Ventures, and Caffeinated Capital also participated. The company has now raised $138 million in total, according to the announcement.

The Arlington, Va.-based startup operates in a corner of defense technology that has traditionally relied on government contracts and classified work. The size of the round and the valuation suggest venture investors see a path to scale outside the standard procurement cycle. Cyber warfare tools – offensive and defensive – have drawn growing interest from private capital as the Pentagon pushes for faster adoption of commercial tech.

The raise adds to a string of large defense-tech financings over the past two years. Anduril, Shield AI, and others have pulled in hundreds of millions at valuations above $1 billion. Twenty’s entry into that group puts pressure on larger primes with cyber divisions, like RTX and L3Harris, to either build or buy similar capabilities. For public-market investors, the signal is indirect but real: a startup reaching unicorn status in cyber warfare means the talent and deal flow in the sector are accelerating.

Twenty did not disclose how it plans to use the new capital. The round closed earlier this month.
