How we work

We are organized in teams and each team is responsible for one or more customers or services. The team has the overall responsibility for requirements, design, testing and delivery. Some teams focus on delivering telecom and fintech services to our customers, while other teams focus on our core services and operations. A team consists of all the roles needed to build and deliver our services and products, typically back-end, front-end, UX design, QA and a team lead.

Our product stack

We create SaaS and PaaS services for telecom and fintech companies. On top of that, we build native, hybrid and web apps that are regularly used by hundreds of thousands of our customers' users.

Handelsbanken, Resurs Bank, Skandiabanken and Nowo are some of our satisfied fintech customers. We are proud that they have turned to us and pleased to see that the cooperation is constantly deepening. We have created a flexible stack of services and apps that utilize Open Banking frameworks, payment intermediaries and PFM. Our fintech solutions also win prizes, such as Handelsbanken - App of the Year 2018 by magazine Privata affärer, and Skandiabanken - Best Mobile Bank by magazine Mobil.

Telia, Telenor and Tre are some examples of telecom customers. Their prepaid card business rests heavily on our services and apps. We handle subscriptions, payments, loyalty and bonus programs as well as customer communication, content and product configuration. We are already the biggest in our field in the Nordic region. The next step is to show the rest of Europe how much better the prepaid card business will be with our stack.


We are looking for skilled system developers with long experience of building distributed services that are consumed in commercial contexts. Smart Refill provides platforms and builds engaging apps for fintech and telecom customers. We are an unusual team of designers, app and system developers as well as business developers. On the one hand, our services handle hundreds of millions in payment transactions, while our apps are praised as well-designed, innovative and useful.
