Matching funds and public co-investment

In innovation financing there is a category of instruments that many startups underestimate: matching funds and public co-investment mechanisms. Their logic differs from that of a call for proposals or a traditional grant. They are not money you win by filling out a dossier: they are public capital that stands alongside a private investment, multiplying it. Understanding how they work changes the way a capital raise is set up.

The logic: capital that follows the investor

A matching fund is an instrument in which a public (or para-public) body invests on condition that a private investor is already present. The public “matches” its own capital to the private one, according to a predetermined ratio (for example one public franc for every private franc, or in different proportions).

The difference compared to a grant is substantial:

• A grant is a non-repayable contribution awarded based on the merits of the project, assessed by a committee.
• A matching fund intervenes only if someone else — a private investor — has already decided to put capital into the company.

The implicit message is: the State does not want to pick the winners in place of the market. It delegates the selection to the private investor and amplifies their bet.

Why this mechanism exists

Public co-investment responds to two objectives. First, correcting a market failure: in very risky phases or in strategic sectors, private capital alone is insufficient, and public intervention mobilizes it. Second, using the private sector as a quality filter: if a business angel or a fund puts in their own money, they have already done due diligence and believe in the project. The public thus reduces the risk of financing weak initiatives.

A practical consequence follows: co-investment reduces the private investor’s exposure per operation. With the same capital a fund can support more companies, or support the same company with a larger overall ticket. It is a multiplier.

The forms of co-investment

Public co-investment takes different forms depending on the instrument:

• Matched equity: the public enters the capital alongside the private, on the same conditions or on defined conditions.
• Matching on a financing round: the public contribution is tied to a capital increase already subscribed by private investors.
• Funds of funds: the public does not invest directly in the companies, but in private funds that in turn invest, mobilizing capital indirectly.
• Convertible loans or hybrid instruments combined with private capital.

The conditions — matching ratio, caps, requirements for the private investor, eligible sectors — vary from program to program. The common principle remains one: first the private, then the public that follows.

What it means for your fundraising strategy

The key point is to change the order of priorities. With a grant, the first step is the application. With a matching fund, the first step is finding the private investor, because without them the public capital is not activated. The operational consequence:

1. Build the relationship with the private investor first — business angel, fund, club deal.
2. Verify which public instruments can be matched to that round, and with what requirements.
3. Structure the round so that the public co-investment can be activated (legal form, type of instrument, compatible conditions).

This overturns a common mistake: seeking public money as an alternative to private capital. In matching funds the public does not replace the private, it amplifies it. If there is no private, there is nothing to match.

The conditions to watch

Some recurring elements to pay attention to:

• Investor eligibility: often the private party must meet requirements (professionalism, independence, type).
• Timing: the co-investment must be synchronized with the round; misalignments derail the operation.
• Governance: the entry of public capital may entail conditions on reporting and rights.
• Valuation: the economic conditions of the round must hold up even with the public component.

A clean corporate structure and an orderly cap table are preconditions: no co-investment enters a company with confused arrangements.

How we work

Accessing matching funds and public co-investment requires orchestrating two worlds — that of private investors and that of public instruments — in the correct sequence. SIH ONE is an AI-native fiduciary group and supports companies in structuring rounds and integrating subsidized finance into the fundraising strategy, taking care of legal form, cap table and timing so that public capital can actually be activated.
