What philanthropy is leaving on the table in impact stacks

Australian philanthropy has never had more to work with. The largest intergenerational wealth transfer in our history is underway. New foundations are forming. Established ones are rethinking their mandates, and family offices are getting serious about impact.

And yet much of philanthropy's potential is still sitting on the table.

In previous articles, we explored impact stacks and the roles government and private capital play. Philanthropy is where this series lands, because it holds the most distinctive set of tools in the stack and the most untapped potential to put them to work.

Philanthropy: a catalyser, preventionist, risk-taker and experimenter

Government creates the enabling conditions. Private capital scales what works. Philanthropy takes the early risk that makes both possible. Its job isn't to fund every social outcome, it's to fund the ones that need support to make the first move; the ideas that are not yet investable, the models not yet tested and the prevention work that stops problems becoming entrenched.

Warrama-Li shows what this looks like. When the First Nations social enterprise launched in regional NSW, its trade-based model for supporting young people into employment was new and had to build a track record, which meant it wasn't yet eligible for government programs or ready for commercial investment. Philanthropic investment capital was able to fill the gap and funded the evidence base that opens doors to the next layers of capital.

Philanthropy is not supposed to hold this forever. Its role is to help carry the early risk so government and private capital can come in later. When that doesn’t happen, the rest of the stack often never forms. That’s the first opportunity left on the table.

The power of the granting arm and corpus working together

Philanthropy doesn't have one tool. It has two. In Australia, they're rarely used together.

Many foundations restrict their corpus to traditional investment mandates and treat the granting pool and the investment portfolio as separate worlds. The power of philanthropy is truly unlocked when both arms work in concert: corpus taking a commercially structured tranche in a deal, granting capacity underwriting the at-risk first-loss tranche of the same deal.

Sefa's work with Melbourne City Mission on Living Learning shows how this can come to life. Five foundations backed both layers of the structure, the commercial tranche through corpus and the at-risk tranche through grants. The result was a blended capital structure that wouldn't have existed otherwise, built for replication and scale.

When the granting arm and the corpus don't work together, that's the second opportunity sitting there idle.

The sequencer: helping grantees become investees

Many organisations philanthropy backs today could become investees tomorrow. What they lack is the bridge of commercial acumen, business confidence, diversified revenue, and the operational maturity investment capital expects.

Building that bridge takes intentional sequencing. Capacity-building grants now, blended investment in twelve months, mainstream finance later. Philanthropy has the freedom to play this long game better than anyone.

Shopfront shows what this sequencing can achieve. They were supported by philanthropic capital over time, with patient funding and the space to build the financial sustainability that opened the door to repayable capital.

The most powerful grants aren't always the ones that fund the work directly. Sometimes they're those that build the conditions for investment to follow. Without that sequencing, organisations stay grant-dependent longer than they need to.

Philanthropy as the springboard that brings in the rest of the stack

Even when philanthropic capital sits at just one point in a deal, the way it shows up changes who else will follow. A first-loss tranche signals to private capital that the deal has been de-risked. A patient grant signals to government that the model is worth backing at scale. A catalytic investment crowds in family offices and impact investors who wouldn't have moved on their own. Many foundations also constrain their corpus to impact investing within their granting focus areas. The architecture works much more powerfully when the corpus is allowed to follow opportunities across the full breadth of impact, so that philanthropic capital can participate in as many stacks as possible.

To date, $5m in philanthropic capital across 9 blended deals at Sefa has unlocked $10.5m in additional capital from government, private investors and banks. That's the multiplier. That's what philanthropy does when it stops being a single source and starts being the springboard for everything else in the structure.

Bringing everything to the table

Philanthropy doesn't need to decide whether to join impact stacks. The question is whether it will bring all of its tools into them: granting arm, corpus, patience, risk appetite, and the freedom to experiment.

Sefa partners with philanthropy to design and coordinate impact stacks across Australia. As the backbone organisation holding the architecture together, our role is to bring the layers into alignment. Philanthropy's role is to bring everything it has.

If you're a foundation, a philanthropist or a family office thinking about how your capital could do more, we'd welcome a conversation. There's too much potential to keep leaving on the table.
