Partners Capital?

Has anyone heard of / worked with Partners Capital (https://partners-cap.com/)? They position themselves as an outsourced investment office.
 

"Our clients are evenly split primarily between two groups: investment professionals and institutions. Our private clients are predominantly founding and senior partners at leading investment firms, including Blackstone, KKR, Bain Capital, Summit Partners, CVC, Related Companies, Lone Star, BC Partners, Apax Partners and Goldman Sachs. In our capacity of advising investment professionals, we are known as ‘the money manager for money managers’. Our institutional clients include investment committees at 8 Oxford and Cambridge Colleges, 2 Singaporean Universities, Eton College, INSEAD Business School, Guy’s and St. Thomas’ Charity and the Hong Kong Cancer Fund.

Would appreciate any insight on the firm's culture, performance, and reputation.

Thanks!
