Turning nature and resilience value into lasting action.
The Darwin Fund works with partners to protect and restore nature, strengthen communities and build lasting climate resilience.
Our goal is to connect high-integrity outcomes with the evidence, local delivery, partnerships and funding needed to sustain them — and mobilise additional investment where it can genuinely help.
Darwin was established as a blended-finance platform and an on-ramp for institutional investment in nature.
Our founding ambition remains to build towards a $100 million seed fund supporting science-based nature restoration and protection, with long-term aspirations encompassing 60 million acres of rainforest, 100,000 miles of coastal and ocean habitat, and 5,000 at-risk species.
Achieving ambitions of this scale requires more than capital. It requires credible evidence, capable local partners and durable ways of supporting the work.

Forests, oceans, watersheds and other natural systems underpin biodiversity, climate stability, water security, livelihoods and economic resilience.
Yet much of the value they create is not adequately reflected in economic decisions, public budgets or investment markets.
The organisations and communities protecting these systems often face fragmented responsibilities, uncertain funding and limited resources for long-term maintenance.
Darwin exists to help close that gap: making the value clearer, strengthening the conditions for delivery and connecting outcomes to the resources needed to sustain them.
We work with partners to turn promising nature and resilience opportunities into lasting results — building on local knowledge, scientific evidence and the capabilities already in place.
By connecting communities, conservation organisations, public institutions, philanthropy and investors, we help strengthen projects, unlock new opportunities and create the conditions for sustained impact.
Our approach recognises the wider value of healthy ecosystems — for biodiversity, climate, livelihoods and economic resilience — and seeks to translate that value into stronger partnerships, durable funding and investment at scale.
Our ambition is to make protecting and restoring nature an enduring part of how economies develop and prosper.
Decision & Investment Intelligence
Darwin Vantage is Redpill Group's proprietary decision and investment intelligence capability for complex systems, applied by the Darwin Fund to strengthen its work.
It helps answer four questions:
Where does value exist?
What is preventing it from being realised?
What should happen next?
Where can capital genuinely help?
By connecting evidence, economics, risk, policy, delivery, stakeholder priorities and finance, Darwin Vantage helps turn complex opportunities into practical, evidence-led pathways for action.
It is developed and owned by Redpill Group Ltd.


Credible decisions require a clear distinction between what is known, what is assumed and what still needs to be demonstrated.
We examine the evidence relevant to each opportunity — including ecological outcomes, biodiversity, livelihoods, social value, additionality, delivery risk and, where appropriate, carbon.

Credible decisions require a clear distinction between what is known, what is assumed and what still needs to be demonstrated.
We examine the evidence relevant to each opportunity — including ecological outcomes, biodiversity, livelihoods, social value, additionality, delivery risk and, where appropriate, carbon.
Measurement and verification should be proportionate, transparent and useful to the people and institutions making decisions.

Lasting outcomes depend on organisations and communities being able to deliver and maintain the work.
Darwin brings together local partners, scientific expertise, communities, public agencies, philanthropy, investors and other beneficiaries around the requirements of each opportunity.
The emphasis is on practical coordination, local ownership and sustained delivery.

Different kinds of capital solve different problems.
Grants and philanthropy can support evidence, public benefit and early development. Public and institutional funding can sustain essential services. Repayable investment may improve timing, scale or durability where credible revenue and repayment arrangements exist.

Different kinds of capital solve different problems.
Grants and philanthropy can support evidence, public benefit and early development. Public and institutional funding can sustain essential services. Repayable investment may improve timing, scale or durability where credible revenue and repayment arrangements exist.
Our role is to identify the right combination and sequence, without assuming that every opportunity must become an investment product.
Our inaugural Project Prospectus brought together 35 nature-positive project opportunities across 30 countries, spanning rainforests, mangroves, river systems, coastal and coral habitats, sustainable agriculture and nature-linked business models.
It illustrates the breadth of opportunities for high-integrity, locally rooted nature restoration and sustainable development.
The prospectus reflects Darwin's founding ambition to build a globally distributed pipeline of nature-positive opportunities.
Projects differ in maturity, evidence, delivery readiness and financing needs. Understanding those differences is essential to determining what support is appropriate and what must happen next.
For institutions considering nature investment, the prospectus illustrates why early evidence, technical assistance, local partnerships and catalytic funding often need to precede larger-scale finance.
The aim is to create credible pathways towards sustained delivery and, where justified, investment readiness.
Napa County Wildfire Resilience — Phase 1 Complete
Spend before the fire, not just after it.
With support from CSAA Insurance Group, the Darwin Fund has completed the first phase of its Napa wildfire-resilience work using Darwin Vantage.
The study establishes a practical pathway for connecting existing prevention efforts, demonstrating their value and securing more durable funding — with lessons extending well beyond California.
