We are the ReCirculate Collective.
Values-led, action-oriented, changemakers.
Our journey has been anything but ordinary—from community-rooted infrastructure work in India to catalyzing circular impact in the U.S. Through every step, we’ve stayed true to our values and made space for thoughtful, lasting change.

Where We Come From
S3IDF was founded in 2001 to challenge “business as usual” in development finance—especially the top-down systems and exclusionary capital models that leave too many people behind.In our early years, we worked alongside underserved communities in South India, supporting practical solutions across clean energy, sanitation, waste, and livelihoods. Our approach—what Dr. Russell deLucia called the Social Merchant Bank Approach®—combined catalytic capital, local partnerships, and targeted technical assistance to help microentrepreneurs and small enterprises break through market and financing barriers.

How We’ve Grown
As we learned what it actually takes to shift systems, we expanded from on-the-ground work to helping shape larger efforts—advising international development programs and bringing inclusive entrepreneurship and last-mile delivery strategies into broader energy access and market systems initiatives.
In recent years, we launched an impact-first investing initiative in India—backing early-stage startups in clean energy, sustainable agriculture, and circular waste management with flexible, risk-tolerant financing and hands-on support. While we are no longer investing in new Indian startups, the entrepreneurs we supported continue to grow their operations and impact.

Why Circularity?
The challenges we face—climate change, extractive economic systems, and widening inequality—are deeply interconnected. We see circularity not just as an environmental approach, but as a systems-level strategy for resilience, equity, and sustainability: redesigning value chains, reimagining ownership and access, and building models that restore rather than deplete.
To us, “circular and regenerative” is a mindset that shows up in many forms, including reuse and repair, waste-to-value innovation, regenerative agriculture, shared-use models (tool libraries and reuse hubs), and workforce approaches that link environmental goals with economic justice.

What We’re Building
In recent years, we began applying our values to a new context—the United States—where community-rooted circular solutions face familiar barriers: not enough early, flexible, non-dilutive capital—exactly the kind of gap we exist to close.
In 2026, we launched the ReCirculate Collective: a member-powered initiative supporting U.S.-based nonprofit and for-profit efforts advancing circular and regenerative solutions. It’s built on S3IDF’s core approach—creative, catalytic capital paired with values-driven partnership—with a focus on 0% interest loans and non-financial support.

All about ReCirculate Collective:-
ReCirculate Collective is an initiative of S3IDF—a member-powered program S3IDF launched to support U.S.-based circular and regenerative solutions through 0% loans and non-financial support.
Behind the scenes, S3IDF provides the governance, oversight, and final decision-making needed to keep the work aligned with S3IDF’s charitable purpose.
ReCirculate Collective also operates under S3IDF’s nonprofit umbrella (via a wholly owned, single-member LLC structure) so the program can stay focused and financially distinct while still benefiting from S3IDF’s 501(c)(3) status—meaning contributions remain tax-deductible to the extent permitted by law.
-
Both are deeply meaningful—and both help power 0% loans.
A donation is a direct way to support the work and expand the pool of capital we can deploy. A membership contribution is simply the “stay closer to the work” option: it includes year-long access to The Inner Circle (member portal) and optional opportunities to engage more directly (events, borrower check-ins, and—during review windows—participating in application reviews).
Either way, your dollars matter. Membership adds connection and access; donations still move capital and make loans possible.
-
Yes. donations made to ReCirculate Collective are fully tax-deductible to the extent permitted by law. Contributions are routed through ReCirculate Collective’s LLC, which is treated as a disregarded entity for tax purposes, means that donations qualify under S3IDF’s 501(c)(3) charity status.

-
Yes—absolutely. You can donate without becoming a Collective member, and your tax-deductible gift matters a lot: it directly helps us make more 0% interest loans to the circular and regenerative initiatives doing the real on-the-ground work. We could do this without you! description

We take impact tracking seriously. Borrowers share structured updates so we can understand what’s being built, what outcomes are emerging, and what’s being learned along the way.
We share these insights in a few ways:
Public-facing impact highlights and periodic reports (so anyone can see what the work is achieving), and
Donor updates by email with news, milestones, and stories from funded initiatives.
Members also receive access to additional detail through The Inner Circle—such as deeper project updates, borrower check-ins, and other behind-the-scenes learning—while donors still receive meaningful updates that show how their support is being put to work.
