For the fourth year in a row, Geisel Software has earned a spot on the Inc. 5000 list of the fastest-growing private companies in America. The recognition highlights the company's sustained growth and its impact in robotics, AI/ML, and IoT.
WORCESTER, Mass., Aug. 12, 2025 /PRNewswire-PRWeb/ -- Geisel Software, a Worcester-based innovator in custom software for robotics, AI/ML, and IoT, today announced it has been named to the prestigious 2025 Inc. 5000 list of the fastest-growing private companies in America for the fourth consecutive year. This rare achievement places Geisel Software among a select group of companies showing sustained growth and resilience in the nation's most dynamic economic engine: independent, entrepreneurial businesses.
The Inc. 5000 list is the most prestigious ranking of the nation's fastest-growing private companies and represents a unique look at the most successful companies within the American economy. Brands like Microsoft, Meta, Chobani, Under Armour, Timberland, Oracle, and Patagonia gained their first national exposure as honorees on the Inc. 5000.
"Making the Inc. 5000 for a fourth consecutive year underscores our team's deep technical expertise, strong client partnerships, and commitment to impactful work—from space robotics to life-saving first-responder technology. I'm proud of this team's achievement and excited for what lies ahead," said Brian Geisel, CEO of Geisel Software.
The companies on the 2025 Inc. 5000 have demonstrated remarkable resilience, driving rapid revenue growth while navigating inflationary pressure, the rising costs of capital, and significant hiring 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."
Geisel Software's continued growth is fueled by its world-class expertise in developing mission-critical software for advanced technology sectors. The company specializes in robotics, automation, AI/ML, and IoT solutions, with a unique mastery of the full software stack from embedded firmware to cloud applications. This expertise has made Geisel Software a trusted partner for some of the world's most innovative organizations, including NASA, the U.S. Army, Teledyne FLIR, and iRobot. The company's commitment to hiring the top 1% of engineering talent ensures it can deliver robust, secure, and groundbreaking solutions for the most complex challenges.
Geisel Software plays a key role in the Central Massachusetts tech community, and its national success underscores the region's emergence as a hub for cutting-edge innovation.

Methodology
Companies on the 2025 Inc. 5000 are ranked according to percentage revenue growth from 2021 to 2024. To qualify, companies must have been founded and generating revenue by March 31, 2021. They must be U.S.-based, privately held, for-profit, and independent—not subsidiaries or divisions of other companies—as of December 31, 2024. (Since then, some on the list may have gone public or been acquired.) The minimum revenue required for 2021 is $100,000; the minimum for 2024 is $2 million. As always, Inc. reserves the right to decline applicants for subjective reasons. Growth rates used to determine company rankings were calculated to four decimal places.
