🚀 About Us
We’re a Nordic iPaaS product company — not a traditional outsourcing agency.

We’ve built our own product: Frends, a modern low-code integration platform that helps solve digitalization challenges for both global enterprises and smaller organizations. Frends is used across various industries and in private and public sectors. We deliver integrations that automate business processes — making our customers’ operations easier, more efficient, and more effective.
