The Social Business Deal

Your capital funds one pilot hub. If the model performs as projected, capital is recovered over 20–30 months. After recovery, surplus remains with the community.

This is not a dividend investment. It is pilot capital for a Social Business model that must prove uptake, operating discipline, and measurable groundwater demand reduction.

How to Get Involved

Three ways to support the pilot.

01

Hub Investor

Fund one hub. Get your capital back.

Why Now?

Jakarta needs practical groundwater alternatives.

01

2026 Groundwater Ban

Jakarta's groundwater restrictions increase the need for practical alternatives. RainBank focuses on one realistic replacement category: non-potable daily water demand.

02

Capital Relocation

As Indonesia moves its capital to Nusantara, Jakarta shifts focus to urban renewal and climate resilience. Water infrastructure is at the top of the agenda — and community solutions are being actively encouraged.

03

Known Technology

Rainwater harvesting is established technology. RainBank's pilot tests the operating model: local management, transparent pricing, and service continuity across seasons.
