Four Blue Ash companies earned spots on the 2026 Inc. 5000, the annual ranking of the fastest-growing private companies in the United States, the city of Blue Ash announced Aug. 19.

Blue Bridge People, STACK Construction Technologies, Kinettix and Relevate Health all qualified based on percentage revenue growth from 2022 to 2025.

The four honorees span technology, construction software, IT services and healthcare marketing. They represent a slice of the 36 Greater Cincinnati companies that made this year's national list, according to the Cincinnati Business Courier.

Blue Ash has placed companies on the Inc. 5000 every year going back to at least 2019, when eight local firms made the cut. That was more than any other city in the Greater Cincinnati region that year, according to the Blue Ash Advance. The city placed seven companies in 2022 and six in 2023. This year's count is four.

Each honoree brings a different specialty to the Blue Ash corporate corridor:

Blue Bridge People, founded in 2020, delivers AI agent development, enterprise technology modernization and executive search services. The firm holds Minority Business Enterprise certification and also earned a spot on the 2026 Cincinnati Business Courier Fast 55 list, according to the company's website.

STACK Construction Technologies builds cloud-based software used from bid decision through project closeout. STACK is a repeat Inc. 5000 honoree, previously ranking No. 3,511 in 2022 with 147% three-year revenue growth.

Kinettix provides 24/7 IT field services, including staff augmentation and break/fix dispatches for U.S. enterprises. The company ranked No. 1,711 on the 2022 Inc. 5000 with 362% growth and in August 2026 launched a new strategy and transformation office to support its continued expansion.

Relevate Health creates marketing campaigns targeting healthcare professionals across more than 185 brands, delivering over 600 campaigns annually.

To qualify for the 2026 list, companies needed to have been founded and generating revenue by March 31, 2022, and must have reached at least $2 million in revenue by 2025. Nationally, this year's 5,000 honorees posted a median three-year revenue growth rate of 130% and collectively added more than 627,000 jobs to the economy, according to Inc.

Inc. editor-in-chief Mike Hofman said the honorees' growth reflects creativity, resilience and the customer focus needed to build companies that make a lasting impact.

Individual rankings and growth percentages for the four Blue Ash companies are available in the full list at inc.com/inc5000. Inc. will celebrate all honorees at its 2026 Inc. 5000 Conference & Gala, Oct. 14–16 in Dallas.
