about us

Who we are

Duet is led by a multidisciplinary duo with expertise in design & user experience coupled with mobile development. It’s been over 10 years since we’ve started building quality products with established companies and great startups.

We share your entrepreneurial spirit and have experience as founders ourselves. We've helped build apps that have been acquired as well as apps that have grown to over 10 million downloads. We understand your journey.


The values that drive our company


We challenge teams to think beyond the obvious. Although difficult, we believe that this is where true innovation lies: in the struggle that rises by asking the right questions.


We care about finding the right solution and implementation for our products. That is why we stay on top of our industry and its developments, working with the latest technologies.


We collaborate with our clients sharing ideas and working together.

You know the market.
We know how to build products.
Together we think about value.
