Who we are

From idea to delivery

I set up Sponge Hammer to provide programming services to video games companies.

The company fosters an environment where people feel appreciated, solve exciting problems and be open with each other.
We are focusing on backend services and video game development using the Unity engine.

As we’re a small company, we all have a personal interest in the company’s growth and how we manage our relationships. We do everything to ensure each project run smoothly, and you’re happy with the results.
