What We Do

3Stone Advisors is in three businesses: investing the 3Stone Inflection Fund; investment banking for mid-market clients; and strategic advising. 3Stone has a Cleantech focus – businesses that help reduce impact on the environment while competing favorably on price, quality and performance.
3Stone Advisors is decidedly strategic in everything we do...it's part of our DNA. We bring the strategic thinking of McKinsey & Co., the Goldman Sachs strategic client orientation, and the KKR strategic private equity approach. Management of a company too small to get the attention of Wall Street can work with 3Stone and get an experienced, decidedly strategic partner.
