More than visual design, more than interactions.

We take pride in our craft. Drawing on our deep expertise in design, our Product Design team cares for your users’ experience over the entire customer journey, at every touchpoint with your company.

Building on the work of our Mobile Product Strategy team, we shepherd your product through the entire design process. We aim to achieve your strategic goals while delivering exceptional interactions with visual polish.

We also collaborate with our Software Engineering team to ensure our designs are technically feasible within the constraints of the project. At the same time, we’re watching for innovative new technologies that can make the experience more seamless.

Motion design

Small screens leave less room for you to make your mark. That’s why today, major brands include animations in their style guides. From loading screens to feedback to transitions to branding, Motion Design orients and guides your user while keeping your brand front and center.


Whether you need to validate your ideas with users, get buy-in from your executive team, or demonstrate your concept to your sales staff, we’ll create a prototype that clearly shows what your product can do.

  • Sales prototype
  • Concept video

Design Systems

Design systems are the key to constant iteration and evolution of a product. They promote a cohesive, lightweight user experience by defining not only patterns and styles but how designers use them appropriately. A good system is not just a collection of assets and components; it is the embodiment of a system of concepts.

Voice, Chatbots & Multimodal UI

Give Your Apps a Voice.™

Humans read at ~250 words per minute and speak at ~150 words per minute, but can only type at ~40 words per minute (in English). We all are on a never-ending quest to transmit data to our devices via speech and receive information visually on a screen. The increasing adoption of home assistants like Amazon’s Alexa and Apple’s Siri show a bright future for voice just around the corner. WillowTree champions deeply integrated text, voice, and screen-based experiences—which go by many names, including multimodal, immersive UX, and blended UX—to bring our clients into this new world of voice enablement.
