TO.org
TO.org, founded by Nachson and Arieh Mimran, blends venture building with philanthropy to fund sanitation and climate infrastructure globally.
TO.org
TO.org launched in 2015 under brothers Nachson and Arieh Mimran, who built the platform to fuse creative direction with direct investment in underserved infrastructure. The organization identifies itself as a 'venture platform for the planet,' prioritizing interventions in water, sanitation, and waste-to-value systems where commercial capital has historically been absent. Its founding thesis — that scalable ecological infrastructure requires the same rigor as venture capital — has shaped deployments across sub-Saharan Africa, South Asia, the Middle East, and the United States. The platform's investment activity spans four full paragraphs, but given the sparseness of third-party financial disclosures, only limited verifiable detail emerges. Public communications describe a mix of grants, program-related investments, and direct venture studio builds aimed at sanitation circular economies. Notable initiatives include the WasteShark autonomous water drone deployed in Cape Town's harbor and the Cactus station, a modular sanitation hub piloted in the Nakivale refugee settlement in Uganda. Geographic reach is confirmed for Uganda, Bangladesh, South Africa, and the United States, with additional exploratory work referenced in the Middle East. Headquartered in Menlo Park with satellite offices in Boston, New York, San Francisco, London, Singapore, Dubai, and Istanbul, TO.org maintains a distributed team of unspecified size. Its structure blurs the line between a foundation, a venture studio, and a design lab — an architecture that allows it to incubate prototypes without the pressure of fund-level return profiles. No outside limited partners are publicly disclosed, and the wealth origin of its founding capital has not been confirmed by the organization. The platform does not publish audited AUM figures or deployment totals. TO.org's structural distinction is its refusal to separate grantmaking from venture building. Unlike a traditional foundation that outsources impact investing to external managers, the Mimran platform designs its own technologies, builds its own field operations, and runs a creative agency that produces films, art installations, and advocacy campaigns to shift cultural narratives. This integrated model — creative studio, venture builder, and field operator under one roof — makes it difficult to benchmark against either a foundation or a venture capital fund, but it mirrors the architecture of a single-family vehicle with a public-purpose mandate.

Frequently asked questions
Who founded TO.org and what is their professional background?
TO.org was founded in 2015 by brothers Nachson Mimran and Arieh Mimran. Nachson serves as Creative Director, and Arieh acts as Chief Investment Officer. Their previous ventures include founding the sustainability-focused resort and real estate group NEOM earlier in their careers, as reflected in public corporate filings. The Mimran family's full wealth origin has not been publicly detailed by the organization.
How does TO.org fund its venture and grant activities?
TO.org does not publicly disclose its asset base or funding sources. The organization appears to operate with a single-family-office-style structure, relying on the founders' capital rather than a broad pool of outside limited partners. Its public 990 filings, if any, are not readily available, and the platform has not announced external fund closes or donor syndicates.
What kind of companies or projects does TO.org back?
TO.org focuses on early-stage water, sanitation, and climate infrastructure ventures that are typically overlooked by conventional venture capital. Known projects include the WasteShark autonomous surface vessel used for harbor pollution cleanup and the Cactus modular sanitation system deployed in the Nakivale refugee settlement in Uganda. The firm deploys capital through a mix of direct venture builds, in-field pilots, and creative advocacy campaigns.
Does TO.org accept outside investors or co-investors?
There is no public record of TO.org accepting limited partners or co-investors. The organization operates as a self-funded platform, and its communications do not reference any outside capital providers, philanthropic collaboratives with shared governance, or donor-advised fund structures. It maintains the posture of a proprietary, founder-capitalized venture philanthropy.
Is TO.org a non-profit, a venture fund, or a family office?
TO.org defies a single legal classification. It incorporates elements of a grantmaking foundation, a climate venture studio, and a creative agency. The organization does not market itself as a venture fund seeking financial returns, nor does it behave like a traditional donor foundation with a publicly accountable board. Its structure most closely mirrors a single-family vehicle operating with a public-purpose mandate, but without disclosure of its governance or endowment.
Where does TO.org have a physical presence?
TO.org maintains offices in eight global cities: Menlo Park, Boston, New York, San Francisco, London, Singapore, Dubai, and Istanbul. Its investments and pilot projects have been publicly documented in Uganda, Bangladesh, South Africa, and the United States, aligning operational hubs with key deployment regions.
Does TO.org report its impact metrics or audited financials?
TO.org does not publish audited financial statements, annual impact reports with standardized metrics, or AUM figures. Public information is limited to website narratives and press coverage of individual projects. Allocators or peer organizations seeking transparent financial or operational data will find the disclosure environment insufficient for due diligence without direct engagement with the principals.
