About Imagine H2O

Founded in San Francisco in 2008, Imagine H2O is a global nonprofit set up to accelerate innovation in water. In its sixteen-plus years it has backed more than 80 startups, a portfolio that, by its own account, captures about a tenth of all early-stage investment flowing into the water sector. Three programmes anchor its work: the flagship Imagine H2O Accelerator, an Asia edition described as Southeast Asia's first water-tech accelerator, and the Urban Water Challenge, which puts water-resilience solutions into cities.

Running over eight months, the accelerator equips early water startups with a development curriculum, ecosystem access, marketing and visibility, and warm links to mentors, end-users, and investors. Structured as a 501(c)(3), it takes no equity from the startups it backs, choosing instead to grow the wider water-innovation field through partnerships with industry leaders, utilities, and development bodies around the world.

Early-stage water-tech startups everywhere, Indian ventures in treatment, distribution, monitoring, conservation, and sanitation included, are the natural fit, especially founders serving water-stressed regions who value the network, investor introductions, and the no-equity model. It is online at imagineh2o.org.
