Who we are
Over 20 years investing patient capital
Our story began in 1994 when Keystone’s founders acquired a niche business services company and ran it as day-to-day executive management. They grew the business dramatically through organic growth and multiple accretive acquisitions and eventually merged it into a large publicly traded company. These entrepreneurial roots created what Keystone is today – we invest in market leading companies in close partnership with management. We take each investment personally. We do not have a short-term outlook, preferring to exercise the patience and dedication needed to build highly successful companies. We have operating experience, so we can roll up our sleeves alongside our management partners, respecting and learning from their deep expertise while providing our full support and guidance.
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.
Keystone's approach

SUPPORT
Keystone is single-mindedly focused on working hand-in-hand with business leaders to create long-term value. Investing patient, long term capital affords us tremendous flexibility. It provides us with a risk-return profile in sync with management and allows us to make decisions based on long-term goals while forging true partnerships with our management teams through good times and bad.
Our partnership approach extends to the third-party service providers with whom we work. We have steadfast, long-standing banking relationships providing us strength, security, and reliable financial support, even in uncertain economic times. For investment bankers, brokers, and other intermediaries, we pride ourselves on only committing to what we can deliver. Our size, entrepreneurial approach, and focus results in quick decisions and certainty to close for sellers which we have consistently demonstrated over the last 25+ years.
Providing a strong value proposition for everyone we do business with is paramount. It is how we create value in ways beyond the numbers.
