Fluency Named to the Inc. 5000 List of Fastest-Growing Private Companies for the Fourth Year in a Row

Agentic Advertising Operating System Ranked in the Top 40% of the List

BURLINGTON, VT (August 12, 2026) – Fluency, the Agentic Advertising Operating System (OS) for scaling paid media across search, social, and programmatic channels, announced that it has been named to the 2026 Inc. 5000 list for the fourth consecutive year. The annual list is the most prestigious ranking of the nation’s most successful independent and entrepreneurial businesses. The company ranked No. 5 among the fastest-growing companies in Vermont and in the top 40% overall.

Fluency enables advertising agencies and in-house teams to run ad campaigns across walled gardens like Google, Meta and TikTok and the DSPs that power the open web, without logging into and managing each one separately. The platform works as an orchestration and governance layer that connects an advertiser's data and systems to every platform so campaigns get built, budgets get paced and rules get enforced automatically, the same way every time. That foundation is what lets teams put AI to work on strategy and creative, while campaigns keep running with the same precision at massive scale. Today,  Fluency powers $3 billion in annual ad spend across more than 250,000 campaigns every month. 

“We've spent eight years building infrastructure that lets agencies and in-house teams automate and run their advertising the same reliable way every time, no matter how fast their business grows," said Mike Lane, CEO of Fluency. "Making this list for the fourth year in a row reflects the continued trust advertisers place in us to power their operations with agents that let their teams do their best work, backed by AI that supports them every step of the way.”

This year’s Inc. 5000 recognizes a new class of companies redefining what growth looks like. From AI and advanced manufacturing to healthcare, consumer products, and professional services, these businesses are expanding their impact, creating jobs and proving that entrepreneurial ambition continues to fuel the U.S. economy. Among the 5,000 companies on the list, the median three-year revenue growth rate was 130%, and those companies have collectively added more than 627,208 jobs to the U.S. economy over the past three years.

“Every company on the Inc. 5000 has a story of perseverance, smart decision making, and a refusal to sit still,” says Mike Hofman, editor-in-chief of Inc. “Their growth reflects more than strong financial performance–it reflects creativity, resilience, and the customer focus required to build companies that make a lasting impact. We congratulate all honorees on this significant achievement.”

Within the past year, Fluency was also named one of Vermont's Best Places to Work and named to Ad Age's Best Places to Work list for the second year in a row. The company ranked among the fastest-growing companies in North America on the 2025 Deloitte Technology Fast 500 and was most recently honored in the MarTech Breakthrough Awards.
