The Contacts team is a core team at Wise, dedicated to making adding, finding, and managing your recipients as easy as possible. We own this experience end-to-end: from the scalable platform securing tens of millions of bank accounts customers send to, to the intelligent search algorithms and local integrations (like Pix) that power discovery, all the way to the customer-facing screens where users interact with their counterparties. The team is integral to Wise’s day-to-day operations — if our services go down, Wise goes down.
