At Cambridge Associates, we serve a diverse group of clients including foundations and endowments, private clients, and corporate and government entities. Our original client base of 12 colleges and universities still work with us, and we pride ourselves on maintaining long-standing consulting relationships with our clients. We have enjoyed a 95% average client retention rate over ten years, and nearly all of our new clients come to us from the referrals of our existing client base.
Our partnership with some of the most sophisticated institutional investors has helped us to identify firsthand the best practices for successful investment program development and implementation. These time-tested best practices are now the foundation of our investment consulting philosophy, which underpins our consulting approach for our entire client base. Our extensive client base also enables us to provide one of the most comprehensive nonprofit comparative peer data universes in the consulting industry.
We serve more than 900 clients, ranging from endowments with $50 million in assets to some of the largest government entities and sovereign wealth funds in the world, and we have studied virtually every topic impacting investment success and have an encyclopedic knowledge of best practices.
