Brunt said: "I joined Fundhouse for a variety of reasons. Ultimately, I was drawn to Fundhouse because it stands for the same things I do, namely detailed evidence-based fund research, an emphasis on doing good and, in an industry with many conflicts of interest, its unwavering independence.
"When I was a client of Fundhouse, I saw first-hand that Fundhouse is a true flag bearer of detailed, independent fund research and I can't wait to start."
