Having four alums among the 100 fastest-growing companies is a testament to fintech’s recent growth spurt. Last year, only two—Lending Club (ranked 248) and OnDeck (ranked 726)—made the top 1,000. Since both went public in late 2014, neither qualified for this year’s list.

The increasing number of Inc.’s 500 fintech companies is partially fueled by the swell in funding over the past few years. Inc. Magazine noted this trend in its recent article, Why Fintech Is One of the Most Promising Industries of 2015. It primarily focuses on WePay’s achievements but also highlights growth and success stories throughout the industry.
