One Acre Fund lends farmers a bundle, not money

Over 50 million families in sub-Saharan Africa earn their living from small farms, producing 80% of the continent's food, yet most remain in a poverty trap: they cannot afford improved seeds and fertilizer without credit, cannot get credit without a harvest to pledge, and cannot produce a surplus harvest without improved inputs and the knowledge to use them. Development programs traditionally addressed one gap at a time — seed subsidies, microcredit, extension training — but solving one bottleneck without the others merely shifted the constraint.

Andrew Youn, a Yale graduate and former management consultant, visited western Kenya in 2005 and observed that a small plot of land with improved seeds and proper fertilizer could triple a family's harvest within one season. He founded One Acre Fund in Bungoma, Kenya, in 2006 with co-founder John Gachunga to deliver everything a farmer needed in a single bundled service.

Delivered all four as one bundle through village groups, because each input is useless without the others, and flexible repayments plus insurance kept defaults low.

The four inputs are complements: without credit, farmers can't buy inputs; without inputs, training has nothing to apply to.

Delivering them together through village groups and field officers keeps transaction costs low and creates social pressure for repayment.

Flexible micro-installments aligned to the growing season, plus crop insurance, keep default rates low because no single drought triggers a cascade of defaults.

When customers need several interdependent inputs to succeed, bundle them into one product delivered through one relationship, so no single gap leaves them stuck.

A registered RCT in western Kenya found the bundled program raised maize production about 26% and profits about 16% against a control group. One Acre Fund won the 2023 Hilton Humanitarian Prize ($2.5 million) and was a 2006 Echoing Green Fellow. The bundled-service model became a reference point in agricultural development, influencing how NGOs and governments structure smallholder support programs across East and West Africa. The model was profiled in Roger Thurow's The Last Hunger Season (2012).
