All Great Firms Begin as Challengers
We offer quiet, aligned capital for Founders building what’s next
We Seek Exceptional Founders
We partner with entrepreneurial investors at the earliest moments of building a new firm.
The Founders we seek are masters of their craft. They balance the drive and patience required to build something great. They take seriously their roles as fiduciaries. To those special few Founders, we are here to help.
The Support We Offer
ThreeStone provides working capital and counsel to a small handful of Challenger firms each year. Our goal is to increase the speed and likelihood of your success. No shortcuts or cutting corners, but leaning into the hard work of building something enduringly great.
Institutional Grade, for the Institutional Market
Drawing on decades of institutional LP experience and years of building firms, we prepare Challenger firms to meet the expectations of top LPs.
Our Experience
High Country Advisors is the sponsor and manager of the ThreeStone funds. Since 2017, the firms we have supported have grown by over $10 billion and delivered meaningful results for their institutional investors. Led by a former endowment CIO who has backed over 40 Challenger Firms across asset classes, we have been on the LP side of billions of dollars of sub docs and built a deep library of experience helping firms launch and thrive.
