A private investment office built on patient capital, family values, and 25+ years of shared conviction.
F3 Finance is a niche investment firm rooted in the Praxis Private Office network. For over 25 years, our founding families refined strategies built on one enduring principle: long-term, high-conviction positions in companies where family ownership creates true alignment.
We do not chase trends. We invest alongside founders — in businesses they have built, and intend to keep.
These are the three strategies our founding families have run for themselves for twenty-five years. They are also the building blocks we use when designing a programme with a partner family — used separately, in combination, or alongside positions you already hold.
We invest in publicly listed companies where a founding family retains a meaningful stake. Teaming up with reference shareholders who think in generations, not quarters — committing with conviction and holding with discipline.
We support family entrepreneurs looking for more than capital. Through club-deal structures, our investor-families take minority positions alongside founders — patient, aligned capital without demanding control.
A carefully selected complement to our direct portfolio — positions in private equity and venture capital funds that extend our reach whilst maintaining the discipline of selecting only GPs whose values meet our standards.
We invest alongside families who share our values, and we partner with those who would rather build than buy. Whether you run a family office, lead a family business, or simply want a thoughtful second opinion on a private-markets decision — we would welcome a conversation.
