Accelerating Growth in Technology and Healthcare

Experienced and Active Partners

We’ve been investing in growth stage technology and healthcare companies since 1972 – directly partnering with more than 280 companies and managing more than $2 billion during that time.

With nearly five decades of growth investing experience, we have seen the inevitable challenges that companies face while scaling operations. To help our CEOs and entrepreneurs overcome these obstacles, we bring to bear the full resources of our global platform and network of relationships.

Seeking Capital

Our Growth Equity Approach


Entrepreneurs want to work with investors who ‘get it’ and have a deep understanding of their business. To do this, we adopt a top-down investment approach to identify sector themes and the impact these will have on the market.


We carefully consider each investment opportunity and weigh company-specific dynamics and market cycles against our overall portfolio construction.


Our platform provides value-add services to help our companies scale operations (expanding internationally, refining their go-to-market strategy, etc.), recruit talent (management and board), and navigate the capital markets (raising capital, preparing for an IPO, etc.).


The Adams Street platform provides information flow and a network of relationships that delivers value across all aspects of the investor lifecycle – from sourcing, to investing, to exit.

Capital Support

We invest in companies with proven product and market fit and strong revenue growth. For us, this typically means having at least $5 million or more in annualized revenue with compelling returns on sales and marketing spend.

We typically invest between $15 million and $30 million, with the capacity to invest more. We prefer to lead rounds and join the boards of our companies but have the flexibility to join syndicates as part of larger financings.
