Frequently asked questions
Who runs investment decisions at Alliant Insurance Services?
Tom Corbett, Chairman and CEO, oversees Alliant's strategic direction including its M&A program and affiliate investment arms. Peter Arkley, President of Alliant Specialty, manages key specialty practices. The firm's private credit and real estate affiliates — Alliant Capital and Alliant Real Estate — operate with dedicated management teams under Corbett's oversight.
How is Alliant structured compared to publicly traded insurance brokers?
Alliant is privately held, with Tom Corbett and management controlling the firm. This contrasts with publicly traded peers such as Marsh McLennan, Aon, and Willis Towers Watson, which face quarterly earnings pressure. The private structure enables Alliant's long-duration acquisition strategy, averaging roughly 30 deals annually since 1998, funded partly through private credit facilities.
Does Alliant operate investment vehicles beyond insurance brokerage?
Yes. Alliant Capital operates as a private credit affiliate that originates and services commercial real estate loans and affordable housing tax credit investments. Alliant Real Estate functions as a distinct investment arm. These affiliates generate fee income and investment returns separate from the core insurance brokerage commissions.
What is Alliant's known posture on co-investments alongside external GPs?
Alliant does not publicly market co-investment opportunities to external GPs. Its investment affiliates — Alliant Capital and Alliant Real Estate — originate and manage their own deal flow rather than participating as limited partners in third-party funds. The firm's capital is internally generated from brokerage profits and private credit lines.
How does Alliant source its acquisition targets?
Alliant sources acquisitions through a dedicated corporate development team and long-standing relationships in the insurance brokerage industry. The firm targets specialty agencies with strong regional or vertical market positions. It has completed over 500 acquisitions since 1998, integrating acquired firms while often retaining their existing management and client relationships.
Which sectors does Alliant explicitly avoid?
Alliant does not operate as an underwriter or insurance carrier — it avoids taking insurance risk on its own balance sheet. The firm functions strictly as a broker and consultant, placing risk with third-party carriers. Its private credit affiliate avoids unsecured consumer lending, focusing on real estate-backed and tax credit investments.
Where does Alliant's acquisition capital come from?
Alliant funds its acquisitions through internally generated cash flow from brokerage operations and private credit facilities. The firm does not disclose specific lenders, but its private credit affiliate's expertise in placing similar facilities for clients suggests close relationships with institutional credit providers. No public equity or external private equity sponsor is involved in the ownership structure.
