New York-based private equity firm Aquiline Capital Partners has brought on Mark Graf as an investment professional.
Graf was previously a partner at financial services-focused private equity firm Barrett Ellman Stoddard Capital Partners. Earlier, he was chief financial officer at Cincinnati-based Fifth Third Bank.
Graf brings opearting and investment experience in banking, finance and transaction processing, the firm said in a statement.
The addition of Graf follows last month’s hire of former E*TRADE Financial chief executive Mitchell Caplan as an executive advisor.
Aquiline specialises in financial services enterprises such as property and casualty insurance, specialty finance, securities, asset management, life insurance and transaction processing.
The firm, founded in 2005 as a joint venture between Venturion Capital and Marsh & McLennan chief Jeffrey Greenberg, closed its debut fund on $1.1 billion last year. Greenberg, the son of former AIG head Maurice “Hank” Greenberg, resigned from the insurance broker in 2004 amid bid-rigging and price-fixing allegations levied by then New York attorney general Eliot Spitzer.
