Irina Denisenko
Knox
A five year wait. A five minute call.
The short version
Irina Denisenko founded Knox after discovering that hundreds of software companies were locked out of federal government contracts because clearing security took years and millions of dollars. At her previous company, Class.com, she solved her own access problem by cold-calling a company that hosted Adobe's federal environment and acquiring it a year later. Knox is built to share infrastructure across companies so they can operate securely in federal environments without building the same security foundation from scratch each time.
- Irina Denisenko previously ran Class.com, where the Air Force wanted to use its virtual classroom software but faced a five-year security clearance timeline.
- She cold-called a company hosting Adobe's federal environment and acquired it a year later to solve the access problem.
- The U.S. government spends more than $100 billion a year on federal IT, yet advanced software often takes years to reach federal users.
- Knox shares infrastructure across companies so they can operate securely in federal environments without each one building its own security foundation from scratch.
- Denisenko compares the old model to building a custom house in an exclusive neighborhood versus Knox's approach of building a condo tower with shared infrastructure.
- She believes that proving Knox can run production securely in federal, the hardest security bar in the industry, will make expansion into healthcare and finance easier.
Somewhere in Virginia, there is a cave. When a federal employee retires, the paperwork gets driven there, where someone carries it by hand from one side of the room to the other. That story went viral last year. It reportedly takes about three years to fully process a single retirement.
Irina Denisenko doesn’t work on retirements. But she’s spent years staring down a version of the same problem. The U.S. government spends more than $100 billion a year on federal IT, and some of the most advanced software in the world still takes years to reach the people who need it most.
At her previous company, Class.com, the Air Force wanted to use its virtual classroom software. She wasn’t selling them an F-35. It was classroom software, and it was still going to take five years to clear security. So she found a company already hosting Adobe’s federal environment, not Adobe itself, just a contractor doing the hosting. She called them cold: “Hey, you’re not Adobe, but you’re hosting Adobe stuff. Do you do that for other people?” A year later, she owned the company.
What started as a fix for one access problem turned into a much bigger one. Hundreds of software companies were locked out of one of the largest technology buyers on earth, not for lack of quality, but because getting in the door took years and millions of dollars nobody had.
Knox was born out of that realization. Irina compares the old model to building a custom house in an extremely exclusive neighborhood, years of work and millions of dollars before you can move one piece of furniture in. Knox built the condo tower instead, sharing infrastructure so companies can operate securely without laying the same foundation from scratch every time.
Her ambition isn't just a faster process. Federal is the hardest bar in the industry to clear, and she's betting that once Knox proves it can run production securely there, expanding into healthcare and finance is the easy part. "We're starting in the Olympics of cloud security," she says.
Conversation Nibbles
An appetizer before the entrée
Just pick up the phone: Irina’s acquisition story started with a cold call. Her philosophy is simple: make the call and see what happens. The downside is usually much smaller than we imagine.
Solve the problem, don’t chase the title: Irina never set out to become a CEO. She believes the strongest founders are obsessed with solving something real first. Leadership becomes the consequence.
Execution beats strategy: Ideas are everywhere. The ability to actually execute is what separates companies.
You only need a small edge: Roger Federer reportedly won just over half the points he played. Irina uses the analogy for leadership—win slightly more than you lose, recover quickly, and compound the advantage.
Enjoy the podcast. I promise the DMV conversation alone is worth it.
