A Finnish-Polish software company built on expertise

Practical, senior-level engineering in AI, data, and product development — since 2020.

The Story So Far

Polar Night Software started in 2020 with a clear goal: to bring together Finnish and Polish expertise to build reliable, modern software. Since then, we’ve focused on AI, data platforms, and product development, helping companies turn ideas into working solutions.

From the start, our approach has been straightforward - small, senior teams working directly with clients, without unnecessary layers or overhead. We prefer practical solutions over buzzwords, and we stay close to the code from concept to launch.

Our Workplace

With roots in Finland and Poland, we combine remote flexibility with a collaborative way of working. Our teams are compact and focused, which means faster decisions, clearer communication, and results that stand the test of time.

For us, building products is not just about technology. It’s about trust, long-term collaboration, and making a real difference for our clients.

OUR CORE VALUES

What we stand for

Trust in practice

We believe trust is earned through what we deliver, not what we promise. That means staying transparent in our process, accountable for our choices, and fully aligned with our clients' goals - every step of the way.

Global roots, local precision

Born in Finland and Poland, we carry both cultures in how we work: Nordic simplicity blended with Central European attention to detail.

Small teams, big responsibility

We keep teams lean so decisions are fast and ownership is clear. Without layers of hierarchy, every engineer, designer, and PM takes responsibility for the outcome - and that makes the work stronger.

The Polar Night Team

Our work is always as good as people behind it. We all share the vision that motivates us to develop the best possible solutions for your business needs.
