Global migration is a 21st-century reality. Whether people are fleeing from something or racing towards an exciting opportunity, following love or seeking new experiences, more and more people are living in different places and in new ways. 

We connect ambitious people abroad with their families and friends back home so they can support each other, lose less of what was left behind, and lead more enriched lives.

With international calling, mobile top-ups, international money transfers and more, we design products with the needs of modern migrants in mind.

Our ambitious team reflects our international audience. We are a diverse group of people from all over the world that come together every day - to create meaningful products that bridge the distances created by national borders.
