Stone Fruit Holdings is a Single Family Office based in Philadelphia, Pennsylvania.
The returns of the next twenty years will come from physical capacity, not software alone: power, factories, machines and land, with intelligence layered on top. We own businesses at that intersection.
The office
About the office
We manage the family's capital directly, across seven sectors, both in operating companies and through a small number of fund managers.
Physical capacity is slow. A fabrication line, a refinery, a rail connection or a farm takes years to build and longer to prove, and much of it now has to be rebuilt in the United States after decades of it being built somewhere else. Work on that timescale needs owners who can wait.
We are not a fund. We do not raise outside capital, we have no limited partners, and there is no fund life. Investments are held for as long as they continue to earn a place.
Sectors
Where we invest
Electrification, charging infrastructure, advanced air mobility, and the ground infrastructure that supports them.
Generation and grid infrastructure, oil and gas, and nuclear technologies from the fuel cycle through to advanced reactors.
Applied systems with established commercial demand, together with the compute and data assets on which they depend.
Dual use hardware and software serving the United States and allied governments, their prime contractors and the wider industrial base.
American factories that employ American workers, and the tooling, automation and machine tools that keep them competitive.
Industrial, energy adjacent and mixed use assets, held for income and for long term land value.
Working farmland, controlled environment production, and the equipment, inputs and logistics that support them.
Approach
How we invest
-
Direct investments
We acquire control positions and significant minority interests in operating companies. We prefer a smaller number of larger commitments.
-
Fund commitments
We commit to a limited number of managers in sectors where specialist expertise adds value, and we tend to reinvest with managers we know well.
-
Holding period
Our default holding period is indefinite. We underwrite on the basis of long term ownership rather than a planned sale.
-
Assets and operators
We favor hard assets, physical supply chains and experienced operating teams with a demonstrated record in their sector.
-
Process
We are a small team and decisions are made directly by the principals. We respond to proposals promptly, whether or not we intend to proceed.

Inquiries
A short summary of the business, its financial performance and the role we would play is sufficient. We review every proposal we receive and respond to those that fall within our areas of focus.
