NEW YORK, August 12, 2025 – Ampirical has once again been recognized as one of the fastest-growing private companies in the United States, earning the No. 3652 spot on the prestigious 2025 Inc. 5000 list. This marks the eighth time Ampirical has appeared on the list—an achievement fueled by a three-year growth rate of 105%—placing the company among a small group of honorees that are driving innovation, creating jobs, and fueling the U.S. economy.
The Inc. 5000 list provides a data-driven snapshot of the nation’s most successful independent businesses, with past honorees including Microsoft, Meta, Chobani, Under Armour, and Patagonia. This year’s honorees have thrived despite economic uncertainty, inflationary pressures, and a challenging labor market.
Ampirical’s recognition on the Inc. 5000 list reflects its commitment to delivering reliable, sustainable energy infrastructure solutions. By partnering with clients on transmission and distribution networks, substations, and turnkey EPC services, Ampirical helps build stronger communities and supports the growth needed to meet today’s and tomorrow’s energy challenges.
“Making the Inc. 5000 is always a remarkable achievement, but earning a spot this year speaks volumes about a company’s tenacity and clarity of vision,” says Mike Hofman, editor-in-chief of Inc. “These businesses have thrived amid rising costs, shifting global dynamics, and constant change. They didn’t just weather the storm—they grew through it, and their stories are a powerful reminder that the entrepreneurial spirit is the engine of the U.S. economy.”
