Organizational Context

The United Nations World Food Programme (WFP) is the 2020 Nobel Peace Prize Laureate.

Around 20,000 people work for the organization, most of them in remote areas directly serving the hungry poor.

ShareTheMeal is WFP’s fundraising and awareness-raising app. Free to download, the award‑winning app is a pioneering way for people to join our efforts in creating a world with zero hunger. ShareTheMeal was launched in 2015 as the first pilot of WFP’s Innovation Accelerator which supports start‑ups and innovators in developing their ideas for zero hunger.

ShareTheMeal currently has more than 1.9 million users worldwide who have shared more than 290 million meals (US$ 200 million). WFP is pursuing an ambitious growth strategy for individual giving and ShareTheMeal is a key driver for this strategy going forward. The team in Berlin and remotely is focused on increasing the funds raised to help reach zero hunger by further developing the app to include new and innovative features, increasing engagement of existing users and growing the user base through marketing and communication initiatives.
