Impact investing has matured — and stalled.

Over the past two decades, the field has grown more sophisticated in measuring outcomes, structuring funds, and refining strategies. Yet for all this progress, the deeper systems we claim to want to change — climate risk, inequality, extractive development models — remain stubbornly intact. In many cases, they are accelerating.

This raises an uncomfortable question: what if the limitation isn’t capital, but how we organize it?

Most people enter the impact finance space through the narrow gate of investment strategy — asset classes, portfolios, risk-return profiles. What they are rarely trained to see, let alone build, are the systems required for transformation.

And transformation, not optimization, is what the moment demands.

Why working inside the system isn’t enough

Buckminster Fuller famously observed: “You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.”

Impact investors often cite this idea — but then proceed to work almost entirely within existing financial architectures. They seek better deals, cleaner metrics, and improved incentives, while leaving intact the deeper logic of the system itself.

The result is a paradox: investors committed to transformation, operating through structures designed for stability, incrementalism, and the old way of doing things that has produced our crises.

This is not a moral failure. It is a strategic and structural one.

True systems change requires something more difficult than deploying capital differently. It requires building parallel financing ecosystems — bridges between today’s financial system and the future systems we say we want.

From funds to ecosystems

Through five years of work with the Financing Ecosystems for System Transformation (FEST) community, a pattern has emerged across very different contexts — from global initiatives like the Climate Investment Funds, the Ocean Risk Reliance Action Alliance, and Co-Impact, to place-based efforts in Sicily, coastal Canada, and Latin America.

Impact investors often cite [Buckminster Fuller] — but then proceed to work almost entirely within existing financial architectures.

What unites successful transformational efforts is not a single fund, instrument, or investor type. It is the presence of an ecosystem — a coordinated network of actors playing complementary roles over time.

A Mental Model Shift

Most impact investors initially think of their work in relatively linear terms: someone has capital, someone has a project, and the challenge is creating a productive connection.

Those who are successful learn that transformation depends on a broader and more intricate network of relationships — not on capital acting alone. What distinguishes ecosystem approaches from deal-based investing is an expanded understanding of how change actually happens.

Financing transformation requires:

• multiple forms of capital (public, private, philanthropic, social, ecological),
• a variety of roles ,
• and actors willing to coordinate rather than compete.

Where conventional impact finance often asks, “Where should I invest?” ecosystem thinking asks a more fundamental question:

“What roles must exist for transformation to be possible — and which ones are missing?”

The roles that make transformation possible

Across the cases studied, several recurring roles appear — sometimes embodied by a single organization, more often distributed across many.

There is no single entry point. What matters is recognizing that your capital is one role among many, and that lasting change depends on how well those roles connect.

Some actors provide capital. Others blend different forms of capital to match stages of change. Some aggregate projects or investments; others broker relationships between capital holders and on-the-ground initiatives. Still others innovate financial tools, build capacity, assess impact, or advocate for enabling policies.

What matters is not the labels, but the insight: no single actor — and no single investment — can carry transformation alone.

When these roles are absent or disconnected, even well-intentioned capital struggles to move beyond pilots and proofs of concept. When they align, systems begin to shift.

Why this is so hard

If financing ecosystems are so important, why are they so rare?

Because they require investors to step outside familiar identities.

Ecosystem builders must tolerate ambiguity, long timelines, and shared credit. They must invest in relationships, capacity, and learning — often without clear attribution or immediate returns. They must bridge belief systems, cultural differences, and power imbalances between financiers and local actors. They must create roles designed for transformation and new values.

In short, they must value system health over deal flow.

This runs counter to much of today’s impact finance culture, which still rewards speed, scale, and singular success stories.

Where an investor actually starts

For investors drawn to transformation, the question is not “Which fund should I back?” but “What ecosystem already exists — or could exist — around the change I care about?”

Some investors enter through philanthropy, others through public finance, private markets, brokerage, or tool innovation (e.g.: social bonds, community funds). There is no single entry point. What matters is recognizing that your capital is one role among many, and that lasting change depends on how well those roles connect.

This means:

• seeking partners, not just deals,
• funding connective tissue, not just outcomes,
• and supporting experimentation and learning, not just execution.

A choice for the Impact Economy

The impact economy now faces a choice.

It can continue refining investment strategies within existing systems — producing incremental improvements while structural crises deepen. Or it can invest in the harder work of building the ecosystems required for transformation — accepting uncertainty, complexity, and collaboration as the price of real change.

If impact investing is serious about making obsolete the systems it critiques, it must first learn to build the systems that can replace them.

That work is already underway — but it remains fragile, underfunded, and poorly understood.

The question is whether capital will meet it where it is.
