Once upon a time...

Five misfits from ManTech decided ManTech was doing it wrong and ventured out to plot a different course. Two of the misfits, Dan Hall and Mike Viscuso, were tired of being told they weren’t allowed to reward and care for their employees, as that would be too expensive. Bonuses went to the executive compensation plans, rewarding people that had performed years ago, but not within the last year. To make matters worse, there was an utter lack of research dollars. Their innovative group had many ideas, but lacked the money needed to truly accelerate. Something had to change. They believed that if they were capable of solving tough problems for clients, contract funding would take care of itself, creating money for research in the process. They were taking a risk, but they knew they weren’t wrong.

“...they weren’t allowed to reward and care for their employees...”

In the beginning, there was Kyrus

The original story of Legion Capital starts with a boutique government contractor the five guys created and named Kyrus Tech, after the Greek god of luck and opportunity. They wanted to take their government contracting proceeds and reinvest them in technology ideas, using humility as a guiding force. It took some time and patience to secure their first government contract, but it wasn’t long after their first revenue win that fate paid them a visit.

"...fate paid them a visit."

One man’s breach is another man’s opportunity

Kyrus incubated the sensor known today as Carbon Black Responder, which is essentially a video camera for your computer that records execution at the endpoint where all malware lives. With a slew of entrepreneurial problems becoming apparent, Carbon Black made slow progress. Mike Viscuso pitched dozens of venture firms to no avail. Kyrus was profitable in those days, but the reinvested capital required to incubate a prototype technology is quite different than the capital required for a start-up.

“...taking what we make and reinvesting it in people.”


We witnessed the brilliance that only a first-rate private equity firm could produce. Blackstone leadership challenged its CTO and CISO to rethink their overhead security spending and use that budget to invest in innovative security technologies, becoming early adopters in their own investments at a much lower price point. The quest to find new technologies led Bill and Jay to find Mike Viscuso and the endpoint product idea that was in the works. Blackstone became the seed investor (we are told but can’t confirm that Carbon Black was the smallest investment in Blackstone history) and this gave us the jolt we needed. Two years later we found ourselves selling the technology to Bit9, the Boston based standard for whitelisting security technology.

While waiting in the Blackstone lobby for the meeting to sign the deal documents, Dan Hall and Mike Viscuso thumbed through a coffee table book on the history of Blackstone. The book told the story of the founders’ beginnings, how they mortgaged everything they had and eventually created success. This success was defined by how much money the founders were worth and how many billionaires were fund investors. Legion Capital comes from more humble beginnings. We believe in taking what we make and reinvesting it in the people we were three years ago. In the technology world, especially the world of computer security, investors bet on people who have been there, done that. We had no past successes to put in our investment deck, and we didn’t want to rely on yesterday’s innovations. Something had to change.
