Case Study

Zero App

Innovation, Derisked

When serial entrepreneur Mike Maser wanted to reimagine his fasting app, Zero, he knew he needed deep product expertise to create something people love and use every day. He knew beautiful design alone wasn’t going to cut it — he was looking for a team to think with and answer the big, important questions. He came to AJ&Smart.


Time-to-market accelerated

Our team used Design Sprints to identify and solve the product’s biggest challenges, design a beautiful prototype, and validate it with customers — compressing the design timeline from several months into just two weeks.

From prototype to market leader

After the Sprint, Mike had everything he needed to build the new version of Zero — which went on to help users do over a 100 million fasts, while getting over 20k downloads per day!

The Design Sprint was crucial for speed and not getting into analysis-paralysis. [...] Working with AJ&Smart compressed the timeline for me from maybe months to a few weeks.
