In most sponsor-led deals, the sponsor, or general partner, puts in a small share of the equity and earns a promote: a larger share of profits once investors have received an agreed return. Limited partners provide most of the capital and receive most of the profit up to that hurdle. The structure rewards sponsors for performance and has served private real estate and private equity for decades.
A family office can participate on either side of that line. Investing as a limited partner is the familiar route. Participating at the GP level, by funding part of the sponsor's own commitment in exchange for a share of the promote, is less common and asks more of both parties.
Why would a family consider it? For the sponsor, GP capital can be hard to find. Lenders and limited partners often require the sponsor to invest meaningfully in each deal, and a growing firm may not have the balance sheet to keep pace with its pipeline. A patient partner at the sponsor level can bridge that gap without forcing the firm to give up control or take on investors with a short horizon.
For the family, a GP position means sharing in the economics that reward good execution, and seeing the business from the sponsor's side of the table. It also means taking on more risk. Promote is earned only if the deal clears its hurdle; if it does not, GP capital can be the first to feel the loss. That is why we approach these positions carefully.
Our questions are straightforward. Has the sponsor done this kind of deal before, through more than one market? Is the sponsor's own capital at risk alongside ours? Are the promote terms, hurdles and decision rights written down clearly, with no ambiguity about who decides what? And would we be content to hold the underlying asset if the plan took twice as long as expected?
We also care about how the relationship works day to day. A GP partner is closer to the operation than a limited partner, so reporting, communication and trust matter more. We do not want to run a sponsor's business; we want to understand it well enough to be useful and to be told early when something changes.
Not every sponsor wants a partner at the GP level, and not every deal suits one. Where it fits, though, the structure can align a family's long horizon with a sponsor's ambition in a way that benefits both. Every arrangement is different, and each is negotiated on its own terms.
