The Experienced &
Reliable Co-Investor

Preferred Partner

Our dedicated team, consistent diligence and closing processes, and longstanding commitment to co-investments makes us an attractive partner for general partners around the world.

Proud Legacy

Adams Street’s foundations lie in direct investing. Our firm has been investing directly in portfolio companies since 1972, and as a buyout and growth equity co-investor since 1989.

Flexible Mandate

We invest in companies of all sizes, with a particular emphasis on small and mid-sized companies with exceptional return potential. In all cases, we strive to partner with the highest-quality sponsors.

Our Approach


We are disciplined in our decision-making, carefully considering both company-specific risk/return dynamics, along with how each investment fits from an overall portfolio construction perspective.


We only invest in deals that are backed by strong general partner sponsors. We assess each deal’s risks and opportunities, then combine these with our views on entry and exit valuation to determine the most attractive investment.


We operate as part of a global platform, leveraging the relationships, knowledge and experience of our staff in every stage of the investment process in order to better source and diligence investment opportunities.
