Insurance Business America (IBA) has unveiled its 2025 list of the fastest-growing insurance brokerages in the US.
The list spotlights firms that posted significant revenue increases over the previous fiscal year.
IBA launched its annual Fast Brokerages initiative in January 2025, inviting insurance firms to submit their financial results for the 2023 and 2024 calendar years. Participants were also asked to share key business developments that contributed to their growth.
To qualify for the distinction, brokerages needed to report revenue gains of at least 15% year-over-year.
Submissions were reviewed to assess not only financial metrics but also structural and strategic developments.
Alliant Insurance Services was among the organizations recognized for growth. The brokerage has expanded nationally, emphasizing talent acquisition and cross-functional collaboration. The firm attributes its performance to a decentralized approach that prioritizes internal cohesion and business agility.
RT Specialty, the wholesale division of Ryan Specialty, also earned a spot on the list. The company delivers a broad range of specialty insurance offerings, including coverage for property, casualty, professional liability, and workers’ compensation. RT Specialty operates through both traditional open market channels and delegated authority platforms.
The complete list of awardees and profiles of featured companies can be found in the “Fast Brokerages 2025” special report, now available on the IBA website.
