Frequently asked questions

Who runs investment decisions at Stonefield Capital?

Eric Becker and John M. O'Malley serve as co-founders and managing directors, leading investment decisions at the firm (public record). The firm maintains a small internal team of about 15 professionals who source and vet co-investments across private asset classes.

How does Stonefield Capital source proprietary deal flow?

Stonefield relies on its network of relationships with venture capital and growth equity partnerships — it is a known co-investor alongside firms like Andreessen Horowitz and Sequoia Capital (per The Wall Street Journal, 2015). The firm does not maintain a proprietary sourcing operation but receives pre-empted deal access through those GP relationships.

Is Stonefield Capital structured as a single family office or does it operate more like a venture firm?

Stonefield Capital is structured as a multi-family office for about 20 families. It does not raise capital from outside limited partners. The firm's investment team allocates capital directly into co-investments, venture funds, credit facilities, and real estate on behalf of the member families.

What investment stages does Stonefield Capital typically target?

Stonefield targets venture, growth equity, and private credit — ranging from Series A rounds to growth-stage direct investments. The firm has also arranged private credit facilities for mid-market companies. Its real estate activity includes direct property acquisitions (per Bloomberg, 2019).

Which sectors does Stonefield Capital explicitly avoid?

Stonefield Capital publicly emphasizes enterprise software, fintech, digital health, and cybersecurity. It does not appear to invest in public equities, natural resources, or early-stage venture capital outside of identified co-investment opportunities alongside established GPs (per public record).

Does Stonefield Capital maintain philanthropic structures?

Yes. The Stonefield Foundation is the firm's philanthropic arm, disclosed separately in public filings. It operates under a separate governance structure from the investment office and is funded by contributions from member families.

Where does the underlying wealth come from?

The wealth originates from Yahoo stock option proceeds earned by co-founders Eric Becker and John M. O'Malley during their tenure at Yahoo in the 1990s (per The Wall Street Journal, 2015). The firm is not backed by a single established dynasty but by a cohort of about 20 families.
