Every operating partner who has sat across the table from a large institutional equity partner knows the moment. The institution likes the business plan, likes the team and is ready to write the cheque for the vast majority of the equity. Then comes the condition: the operator must invest alongside, typically around 5% of the equity, so that both sides win and lose together.
That GP equity requirement is sensible. It is also expensive. On a £100m equity raise, 5% is £5m of the operator’s own money — per deal. An operator running several deals a year can find that its balance sheet, not its pipeline, sets the pace of growth.
The co-GP model exists to close that gap: growth paced by pipeline, not by balance sheet.
The GP co-investment, added up

What is a co-GP?
A co-GP is a capital partner that funds part of the operating partner’s equity commitment, sitting on the general partner side of the deal rather than alongside the institutional investors.
The institutional partner
Provides the large majority of the equity and receives a preferred return.
The operating partner
Sources, builds or manages the asset, contributes its GP co-investment, and earns a share of profits above agreed hurdles — the promote.
Where the co-GP sits
Exhibit 2A co-GP steps into the GP side. It contributes some of the GP equity in exchange for a share of the GP’s economics. The operator still leads the deal, still controls the business plan and still faces the institution. What changes is how much of its own capital it has to tie up to do so.
Why it matters now
The operator-plus-institution structure has become the standard way to deploy capital into operational real estate across Europe and the UK. Large equity partners increasingly prefer to back specialist operators — in living, logistics, hospitality, student, healthcare and data infrastructure — rather than build those capabilities in-house.
That shift rewards operators who can execute repeatedly. But each new deal brings a new GP co-investment, and three pressures make it harder to fund.
Scale of opportunity
Operational sectors are growing faster than most operators’ balance sheets.
Concentration
Funding every deal from the same pool of founder and corporate capital concentrates risk in the operating business.
Opportunity cost
Capital locked in one deal’s GP commitment is capital not available for the next platform hire, acquisition or opportunity.
The operators institutions most want to back are often the ones most constrained by the cost of being backed.
How the economics work
The principle is simple: the co-GP funds the majority of the GP equity in exchange for a preferred return on its equity plus a minority share of the GP’s promote.
The promote rewards what the operator uniquely brings — sourcing, execution and management. The co-GP is rewarded for the capital it puts at risk.
Capital and profit, shared
Exhibit 3What each partner receives, numbered in the order it is paid
- 1Capital back
Each partner’s equity is returned first.
- 2Preferred return
The institution earns its preferred return on the deal, and the co-GP earns its own on its equity. The operator earns none.
- 3Above the institution’s pref.
The institution keeps most of it. The rest is the promote, paid to the GP side and shared: most to the operator, a minority to the co-GP.
- 4Above the co-GP’s pref.
Once the co-GP has its preferred return, part of the further profit on its capital is paid to the operator as promote.
- Capital put in
Everything above the dashed line is return on that partner’s own capital.
Its equity is paid back and earns its preferred return before the profit split, plus a share of the upside alongside a specialist operator.
The majority of the profit above the preferred return on a minority of the capital, so the return on its own equity rises.
| Institutional partner | Operator | Co-GP partner | |
|---|---|---|---|
| Share of total equity | ~95% | Minority of the GP 5% | Majority of the GP 5% |
| Role | Capital, governance rights | Sources, executes, manages | Funds most of the GP co-investment |
| Promote | Pays it | Keeps the majority | Receives a minority share |
Illustrative only. Actual terms depend on each deal, the institutional partner’s requirements and the operator’s track record.
The model works best programmatically rather than deal by deal. A co-GP partner that commits across a series of an operator’s deals gives the operator a dependable source of GP co-investment, and gives itself diversification across assets, vintages and business plans.
Deal by deal, or as a programme
Programme: one relationship funds the gold GP slice of every deal, so the operator negotiates its GP co-investment once.
What each party gets
A well-structured co-GP arrangement leaves all three parties better off than the alternative.
The operating partner
Gets
- Control of its deals and the majority of its upside
- Far less of its own balance sheet committed to each one
- Capital freed to grow the platform
- Less concentration in any single asset
The co-GP capital partner
Gets
- Access to GP-side economics in operational real estate
- A position usually reserved for the operator
- A specialist manager whose interests are tied to the same outcome
The institutional partner
Gets
- A fully funded GP co-investment
- An operator able to keep executing without being constrained by its own capital
Where Co-Win Capital fits
Our interests sit with both the operator and the capital partner. We help operators turn their GP co-investment into a programme rather than a series of one-off cheques: designing the co-GP framework and its economics, preparing the platform for the right capital partners to fit it, and staying involved for the life of the programme.
Our founders, Joris Bodez and Joseph Nolan, bring experience across real estate private equity, structuring and capital raising, and work from London and New York.
