”It was a pleasure to work with Balint and LEAP during our latest design sprint. Balint was very proactive, emphatic and all in all a very funny dude who’s an expert in his field. The final output was all that we asked for and could be used for the development immediately.

”Recently I worked with Bálint on an UX/UI project ... he really gets digital products like our FinTech SaaS. Some of the solutions he came up with surprised me in their simplicity. So working with him is really recommended.“
