Mariner Capital Advisors

Mariner Capital Advisors is a boutique investment banking and business-valuation firm, headquartered in Overland Park, Kansas. Founded in 2002, the firm serves middle-market companies in the U.S., offering a suite of corporate finance services including M&A advisory, capital raising, business valuation (for tax, estate, litigation, and transactional purposes), and strategic advisory support.

Through its advisory work, Mariner Capital Advisors supports business owners at critical lifecycle stages — whether preparing a company for sale, raising growth capital, restructuring ownership, or obtaining valuations for regulatory, tax, or succession planning purposes. Their team of partners, principals, and valuation experts provides technical, financial, and transaction-execution expertise, helping clients navigate complex deals, due diligence, and deal structuring.

Because Mariner is not a traditional investment-fund sponsor but an advisory firm, it does not manage a portfolio of assets for external investors nor publish return metrics like IRR or AAR. Instead, its value proposition is offering specialized expertise and guidance — enabling business owners, stakeholders, and private companies to maximize value, manage risk, and confidently execute mergers, acquisitions, or recapitalizations.
