SOFI · Single Family Offices for Impact

Some conversations only happen between families.

SOFI is a trusted circle of single family offices that invest with purpose. Members bring their experience, explain the deals they are working on and share their diligence and judgement, so that every family makes better, smarter investment decisions.

Co-conceived by the Buyck Family Advisory Office

Our view

Four principles.

  1. Investors in round-table working sessions in a bright atrium

    Governance keeps impact alive.

    Impact is purpose met with dedication. It lasts when it is written down and defines how a family decides.

  2. A full audience at ChangeNOW under the glass roof of the Grand Palais, Paris

    Depth before breadth.

    Start where the family already brings value. Go deep before going wide.

  3. A roundtable session at the LPEA LP Summit

    The next generation decides too.

    Access, vision and the capacity to navigate what comes. Backed by the family’s networks and hard-won experience, they hold the winning hand.

  4. Two investors in conversation over breakfast

    Trust before transactions.

    Relationships matter as much as returns. Trust is built long before the first deal.

Our story

It began in Frankfurt.

June 2024, at the Global Asset Owner Meeting. A few families found they were asking the same questions. They have met ever since.

What SOFI brings

Shared judgement, for better decisions.

Strategy

How other families make their strategy meet their impact goals, and why it holds.

How we look at impact

Impact needs scale, and scale needs wide application: that is basic economics. It takes regenerative capital to build tomorrow’s resilience within planetary boundaries.

How we measure it

The metrics families actually track, and the ones they dropped.

How we review deals

Members explain the deals they are working on, and the room asks the hard questions.

What we avoid

The structures, terms and patterns that have cost families before.

Diligence, shared

What each family learned in diligence, so no one starts from zero.

David Buyck

“Not necessarily to co-invest.
To decide better, together.”

SOFI is a trusted network for better, smarter investment decisions. A clearer view of each family’s co-investment capacity follows from it.
