Customer experience
Anchoring the future of digital products in useful, sustainable and desirable experiences
We help our clients build products that reach their audience and live up to their promises.

We create experiences that are informed by use and designed for impact.
At Theodo, we help our customers transform complex needs into useful, seamless, and truly adopted experiences. We rely on real use — observations, feedback, and usage data — to reveal what creates value, guide trade-offs, and reduce the risks of developing what won't be used. We mobilize AI to map the field of solutions very early on, then explore promising paths through rapid prototyping and confront them with users through regular tests. Thanks to the close collaboration between designers and developers and lightweight design systems, we design experiences that are realistic, consistent and simple to integrate into the product.

Our lean design approach
Trained in the Lean Tech® approach, our teams combine the expertise of strategic design, product design and data-informed design to support our customers throughout the life of their product. They are involved both in the definition of new experiences — paths, interfaces, design systems and associated organization — as well as in the optimization of existing tools in the face of adoption, performance or time-to-market challenges. Among our achievements: the framing and design of new B2B tools, the redesign of B2C applications under severe time constraints, the structuring of digital factories and the implementation of instrumentation and measurement devices to manage the continuous evolution of products.
