Fintech startup Revolut has been growing like crazy and now has 6 million customers. The company has to scale its support team accordingly. That’s why Revolut just announced plans to open a customer operations centre in Porto, Portugal.

There are already 70 people working for Revolut in Porto. Eventually, Revolut plans to hire 400 people in the country. They’ll work on customer support, complaints, investigations and compliance.

And Revolut has been quite successful in Portugal so far. There are currently 250,000 Revolut customers in Portugal, and the company is adding 1,000 new customers per day in the country.

It should help when it comes to hiring local talent. The company is also hiring a growth manager, a communication and PR lead and a community manager in Portugal. Ricardo Macieira, the new growth manager, is the former country manager for Airbnb in Portugal. Rebeca Venâncio, the communication and PR lead, has worked for Microsoft in Portugal. And Miguel Costa, the community manager, has worked for Mog and Nomad Tech.

Earlier this summer, Revolut also announced plans to open a tech hub in Berlin. Originally founded in London, Revolut is slowly building multiple offices across the U.K. and Europe in order to attract local talent.
