Agency EA has landed at #31 on Crain’s Chicago Business 2026 Fast 50 list of the region’s fastest-growing companies. While many honorees leaned on new technology, the Chicago experiential marketing agency credits its growth to a simpler business fundamental: earning client trust.
— Marketing and experiential agencies are under real pressure to differentiate themselves right now. Brands are pouring more money into live, in-person engagement than ever before. Global experiential marketing spending rose by 8.3% to reach $138.94 billion in 2025 and is projected to accelerate another 10.3% in 2026, according to PQ Media’s latest global forecast.
A crowded field of agencies races to out-innovate with new platforms and automation. The AI in advertising market is set to increase to $36.34 billion by 2030, according to GlobeNewswire. However, tools alone fail to retain clients. Agencies that cannot differentiate beyond their tech win one campaign and lose the next. They end up struggling to replace clients instead of retaining existing ones.
Chicago-based Agency EA was named to Crain’s Chicago Business 2026 Fast 50 list, an annual ranking of the region’s fastest-growing companies by five-year revenue growth, landing at #31. This year’s Fast 50 class collectively employs more than 36,000 workers and generated $21.1 billion in combined revenue over the past year, according to Crain’s Chicago Business.
To qualify, companies had to be founded by December 31, 2019, and headquartered in the eight-county Chicago area spanning Cook, DuPage, Kane, Kendall, Lake (Ill.), Lake (Ind.), McHenry, and Will counties. Rather than pointing to a single platform or product launch, Agency EA and several of its fellow honorees traced their growth to a more old-school driver. This driver is how they treat clients honestly and consistently enough that word of mouth generates repeat and referral business. That theme surfaced repeatedly across this year’s list, with multiple executives crediting client referrals, not new technology, as their primary growth engine.
This pattern isn’t confined to marketing. Across this year’s Fast 50 honorees, executives in industries ranging from logistics to healthcare staffing pointed to client retention, not product innovation, as their fastest lever for growth. Several noted that referral-driven clients tend to have lower acquisition costs and longer tenures than those won through paid marketing or new technology rollouts.
For Agency EA, that approach has translated into a 25-year run of client retention built on a team-first culture rather than a single signature technology. The firm’s recent project list includes high-profile activations such as the Obama Presidential Center opening, covered by BizBash in July 2026. It also worked on ongoing projects across live events, hybrid and virtual formats, and long-term brand campaigns. Agency EA is a full-service brand experience agency that has partnered with the world’s biggest brands since 1999. It operates as a division of EA Collective, an independent, 100% employee-owned and majority women-owned organization. The firm’s Fast 50 placement adds to a growing list of industry recognitions built on sustained client relationships rather than any single campaign or technology bet.
