KANSAS CITY, MO and CLEVELAND, OH, Nov. 2, 2026 — CBIZ Benefits & Insurance Services today launched as a standalone company, backed by New Mountain Capital, a leading growth-oriented investment firm with over $60 billion in assets under management. The company operates independently of CBIZ, Inc. and Grant Thornton Advisors LLC.

With more than 1,600 professionals and annual revenue that has grown nearly 40% since 2020 to more than $400 million, CBIZ Benefits & Insurance Services has a multi-decade track record as a trusted partner known for deep client relationships and breadth of expertise, to employers with complex benefits, insurance, and workforce needs.

We are launching an independent company with a strong foundation, a talented team, and a clear vision for the future,” said Michael Kouzelos, Chief Executive Officer, CBIZ Benefits & Insurance Services. “Our clients face increasingly complex decisions around benefits, risk, retirement, talent, and workforce strategy. As a standalone firm, we are uniquely positioned to expand our capabilities and enhance the support we provide to clients as they navigate those challenges. Backed by New Mountain Capital and powered by the dedication of our people, we are exceptionally well-positioned to drive growth, expand our capabilities, and continue building on the trust our clients place in us every day.”

CBIZ Benefits & Insurance Services enters this new chapter as a Top 30 Broker in the U.S., supporting employers nationwide with high-quality service delivered by local teams across nearly 40 markets. As an independent company, the firm will continue to serve employers with employee benefits consulting, human capital advisory solutions, property & casualty insurance, retirement and investment solutions, and individual insurance, with client-facing teams, carrier relationships, service contacts, and day-to-day operations remaining unchanged.

“For more than four decades, we’ve built lasting client relationships through exceptional service, personal attention and a level of care that sets us apart in our industry,” said Polly Thomas, Chief Operating Officer, CBIZ Benefits & Insurance Services. “In this next chapter, our commitment to our clients will not change.
