William Blair entered into a definitive agreement to acquire Inner Circle Sports, a boutique investment bank focused on the global sports, media, and entertainment ecosystem.
Terms of the transaction were not disclosed.
Founded in 2002, Inner Circle Sports is an advisor across the sports, media, and entertainment space, including team owners, leagues, investors, sports operating companies, municipalities, universities, and media/entertainment companies. Services include buy-side and sell-side M&A, limited partner transactions, capital raising, valuations as well as debt financing. Among the deals it has advised on is Synergy Sports, PlayOn! Sports and Teamworks, as well as major team transactions, including Liverpool FC and the Philadelphia 76ers.
The transaction, subject to customary closing conditions and regulatory approval, expands William Blair’s investment banking platform. Inner Circle Sports will continue to operate with its same name for a period of time post-acquisition.
“Inner Circle Sports has built an outstanding franchise anchored by deep sector expertise, trusted relationships, and a strong entrepreneurial culture,” William Blair Chief Executive Officer Brent Gledhill said. “Their approach aligns closely with William Blair’s client‑first philosophy and independent partnership model. As our investment banking activity continues to accelerate, we look forward to expanding opportunities with Inner Circle Sports across our exceptional financial services platform.”
“Expanding our capabilities in sports, media, and entertainment is a key strategic priority for William Blair,” said Matt Zimmer, global head of investment banking. “The sector is experiencing strong secular tailwinds, spanning professional sports as well as youth and collegiate athletics, alongside meaningful opportunities across the broader sports, media, and entertainment ecosystem. Inner Circle Sports further enhances our ability to serve clients and deliver value across these markets, including our private equity clients with exposure to the asset class.”
“When we founded Inner Circle Sports, I could not have imagined how much the industry would evolve,” said Rob Tilliss, co-founder of Inner Circle Sports. “Partnering with William Blair is a natural fit, given our shared values and their ability to further expand our platform and resources. This combination will provide our clients with even greater opportunities going forward, and we are thrilled to be joining Brent, Matt and their team.”
“Joining William Blair represents a compelling next chapter for Inner Circle Sports,” added Steve Horowitz, co-founder of Inner Circle Sports. “Since our founding, we have been one of the most active advisors on control transactions in the team sports industry across the U.S. and Europe. We have had the privilege of supporting exceptional clients during some of their most important and visible decisions.”
“From our early efforts with Liverpool FC and the Philadelphia 76ers to today, we take great pride in the breadth and impact of our work across the global sports, media, and entertainment sector,” Horowitz said. “Our success has been driven by the talent, integrity, and commitment of the people at Inner Circle Sports.”
