Finance is no longer the lifeblood of the business world.

At least that's what Fortune's 40 Under 40 list of the most influential young people in business would have you believe.

In fact, only three people from the traditional finance sphere made the cut this year, while the majority of people on the list come from tech.

Dianne McKeever, Kim Posnett, and Brad Katsuyama ranked 19th, 16th, and 15th, respectively, this year. And while they all work in finance, each of their careers is at least tangentially related to the startup or technology worlds.

We should also note that a number of influencers from the fintech — financial technology — spheres ranked on this year's list. They include Betterment's CEO and cofounder, Jon Stein; PayPal's global head of product and engineering, Bill Ready; and Vitalik Buterin, the creator of the blockchain-based platform Ethereum.
