Longtime banking executive Barbara Turner, veteran board member Wendy Lane and Lauren Taylor Wolfe, the co-founder of Impactive Capital, joined the board in the last days.
Envestnet, which provides technology and automation software for financial advisors and banks, also said it will suggest that all of its directors stand for election every year.
"These appointments were informed by Envestnet's ongoing dialogue with shareholders as we continue to execute on our strategic plan to deliver enhanced value to shareholders," James Fox, Envestnet board chairman, said in a statement.
Impactive, founded by veteran investors Taylor Wolfe and Christian Asmar, owns a 7.5% stake in Envestnet and in January nominated four director candidates to the board.
Impactive blamed poor profit margins and capital allocation for Envestnet's underperformance and said its management and board directors were overpaid.
