From idea to scalable digital product

Custom approach

After initial talks, we propose a dedicated team for your needs.

With the start of a partnership, Lunar's team focuses on understanding your product and its current setup. Once we are aligned, our experts deliver high-fidelity designs and scalable code.

We integrate into your team and take ownership of our initiatives. Thanks to a short feedback loop, we all stay on the right track to the next iteration.

Diverse team

Collective intelligence as a core

Why would you care? One of the reasons — better results.

As academic research and our experience show (ask Pawel, he is a real geek), teams in which members care and listen to others are better-performing teams than those composed of superstars and individualists.

Simplifying, women increase the collective intelligence of teams.

Today, women make up 60% of our technical team.

What industries do we have experience with?
Lunar teams focus on our partner's niche and self-educate accordingly. For 19 years, we have help design and develop products in various areas.More under NDA.
Do we work on fixed budgets?
No. Our goal is to help our partners by delivering the best value. Product development is a complex process. Even with proper initial research and discovery work, we will learn more about the product and its users over time. That influences priorities, the shape of the product, and amount of features.
Committing to what features will be in the product a few months before handing it over for a fixed price is far from optimal for everyone. We never recommend that.
Of course, we prepare a forecast, so you know what to expect.
