Over 30 years investing patient capital

Our story began in 1994...

Keystone's founders acquired a niche business services company and ran it as day-to-day management. They grew the business dramatically through organic growth and accretive acquisitions and merged it into a public company.

These entrepreneurial roots created what Keystone is today. We invest in market leading companies in close partnership with management and thoughtfully scale them.

We had a 25+ year history of investing in businesses using capital entirely within the four walls of Keystone. We take incredible pride and feel a deep sense of responsibility for each investment.

In 2021, we welcomed external investors and have since raised two funds totaling over $1 billion in commitments. Keystone’s employees continue to be the largest investor in both funds.

Keystone's investments all share one thing in common

A mutual commitment by management and Keystone to build a sustainable, market-leading business thoughtfully and patiently.

Our story is just beginning

We are hungry to continue aggressively investing in first-class companies, partnering with great teams, and enjoying the journey along the way.
