We are a digital product design studio with the desire to improve people’s lives through technology. We are driven by curiosity and passion, putting humans first and crafting relationships between people and brands. We approach every challenge with the wonder and curiosity of a child.

Our north star

We believe that the best solutions are created when designers and researchers are both integrated throughout the human-centered design process. At Dupla we built our processes with that in mind. We approach each problem from both perspectives and create a richer point of view, as well as an understanding and empathy for the end user.

The dynamic Dupla

Here's some of what Dupla can do for you.

User Experience Design

We help individuals and corporations go from observation and insights to designs that meet real user needs.

Strategic Research

We uncover habits and practices of target users, identify their explicit and implicit needs, find out what delights them, generate scenarios and analyze trends.

UX Strategy

We choreograph interactions between a brand’s products and services, and people over extended periods of time.


We help organizations develop their brand’s personality and how it relates to its target audience. Based on those insights, we develop a visual identity in a way that enhances the brand.

Usability Research

We perform usability studies with products and services to discover user experience issues and recommend solutions.

Baseline and Benchmark Studies

We perform baseline and benchmark studies to establish a scorecard that describes the experience of a product, how it ranks to user needs and the competition.
