Experienced and Reliable Co-Investor

For more than three decades, Adams Street Partners has actively invested alongside leading private equity sponsors directly into companies. Our firm’s vast resources and long-standing private equity network provide not only robust co-investment deal flow but also a powerful due diligence advantage. With the full support and resources of Adams Street more broadly, the firm’s co-investment platform is recognized globally as a consistent and reliable partner to the global private equity sponsor community.

Deep Co-Investment Expertise

Adams Street’s foundation lies 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.


We are disciplined in our decision making, carefully considering both company-specific risk/return dynamics as well as how each investment fits in the context of overall portfolio construction.


We strive to invest in high-quality companies that are backed by strong equity 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.


Our dedicated team operates 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 perform due diligence on investment opportunities.

Flexible Mandate

We believe the flexibility of our mandate and breadth of solutions sets us apart from other providers. We will consider investments in all sectors and geographies, and in companies of all sizes, with a particular emphasis on the small and mid-market. In all cases, we seek to partner with the highest quality lead sponsors.


We strive to provide flexible solutions to fit the needs of our equity sponsors, along with the ability to engage at any stage. Adams Street offers a broad range of co-investment solutions to sponsors, from traditional LBOs to growth equity, follow-on capital, recapitalizations, and more.
