In the world of financial advice, most of the hard math was settled decades ago by Nobel laureates. The stubborn part was human: getting an advisor and a nervous client to agree, in a single meeting, on how much risk that client could actually stomach. Nitrogen - the company known for its first fourteen years as Riskalyze - built a business on translating that problem into one figure.
That figure is the Risk Number. Built on top of a Nobel Prize-winning academic framework in portfolio theory, it scores an investor's tolerance for risk and scores their portfolio's risk, then keeps the two roughly aligned. It sounds modest. In practice it became a shared vocabulary: more than five million investors have received a Risk Number, and the term traveled far enough that competitors now describe themselves in relation to it.
Founded in 2011 by Aaron Klein, Mike McDaniel and Matt Pistone, the company started narrow - measure risk tolerance, risk capacity and portfolio risk. Advisory firms quickly discovered the data was good for more than suitability. It helped them win clients, keep clients, and set expectations before markets got choppy. So the product grew.
Today Nitrogen describes itself not as a risk tool but as a growth platform. Its software snaps into the gap between a wealth firm's marketing, its CRM, and its asset platform, aiming to create a consistent client experience from first contact through ongoing reviews. The company says it has poured more than $50 million into research and development to get there.
The name change in May 2023 was the outward sign of that shift. "Riskalyze" described one feature. "Nitrogen" - the element essential for growth - was chosen to describe the ambition. The Risk Number stayed; the framing around it got bigger.
