The combined firm will operate under the INVESCO Private Capital name, and be led by Parag Saxena. Both firms now provide funds-of-funds to institutional investors, stand-alone accounts, and high net worth clients.
The senior investment team for the funds-of-funds offerings will consist of Parag Saxena, Katherine A Cattanach, Mary Frances Kelley, Ray Maxwell, and Phil Shaw.
INVESCO Private Capital will continue to offer a series of funds that focus on direct venture capital investments, the announcement said.
