WeFarm uses AI to connect small-scale farmers to crowdsourced farming information.

Labelling itself 'the internet for people with no internet', it uses simple mobile phones to connect some of the 500m smallhold farmers around the world; many are offline and miles from the nearest village.

The service has 191,000 users in Kenya, Peru and Uganda and has sent more than 5.2 million texts, hosted 57,000 questions and received 97,000 answers.

Earlier this year it received $5 million in additional seed funding, taking its total to $6.6 million.
