Software and services sector continues to dominate list with life sciences and fintech placing second and third in 31st annual ranking of fastest-growing businesses

NEW YORK, NY, Nov. 19, 2025 — Deloitte today released its “North America Technology Fast 500™, an annual ranking of the fastest-growing North American companies in the technology, media, telecommunications, life sciences, fintech, and energy tech sectors, now in its 31st year.

Technology Fast 500 awardees are selected based on percentage fiscal year revenue growth from 2021 to 2024. Overall, this year’s Technology Fast 500 companies achieved revenue growth ranging from 122% to 29,738% over the three-year time frame, with an average growth rate of 1,079%.

“This year’s rankings highlight both enduring leadership and breakthrough growth,” said Wolfe Tone, US Deloitte Private & Emerging Client Portfolio Leader. “More than half of the winners are prior honorees, yet the majority of the top ten are first-time entrants—demonstrating the staying power of established leaders alongside the accelerating growth of new innovators across key sectors. As in previous years, private companies continue to dominate, underscoring the agility that private enterprises bring to competitive markets, enabling the exceptional triple and quadruple digit growth reflected in these rankings.”
