Enterprise solutions to Poverty, Health and Climate Change

Our focus

Startle is an impact innovation incubator that identifies, tests, launches and grows enterprise solutions
in the WatSan, Agriculture and Renewable Energy sectors.

By turning challenges into attractive commercial opportunities, we create scaleable pathways to sustainable growth.
Water, Sanitation & Hygiene

Lack of safe drinking water, sanitation and hygiene cause much disease worldwide.

In Madagascar, a Startle venture provides safe water through low-cost drilling techniques.

Globally, a new Startle venture sells an innovative handwashing solution especially suitable for refugee situations.

Renewable Energy: solar & solid fuels

Clean & affordable energy is key to sustainable economic development.

Startle is scaling two ventures that produce sustainable charcoal used as a cooking fuel by low-income consumers in Kenya and Madagascar.

A startup in Kenya provides prepaid (solar) electricity to off-grid households.

Agriculture & Food Security

Improvements in agriculture can have large positive impact on food security, poverty and climate change.

Startle is presently undertaking market research into two exciting agri-ventures.


Startle measures its performance against financial as well as social & environmental metrics.
