Nicolas Simon

Hello, I'm Nicolas, a Product Designer & Builder based in Paris, formerly at Yousign, Microsoft, Voyages-sncf, AXA.

I design digital products in complex environments:

Contexts where speed is key, but mistakes are costly.

I help ambitious companies transform their vision into impactful products by contributing to their high growth, increasing their revenue, and accelerating learning cycles. I work in both B2B and B2C, with a preference for products where users are also the customers.

My approach is simple: clarify, don't complicate.

Understand user behaviors and business challenges. Align the two. Design creative and realistic solutions, with a focus on results.

I now design and deliver functional prototypes using generative AI to reduce feedback loops and accelerate decision-making.

Contact me to benefit from my 15+ years of experience.

I design and build digital products where complexity is the norm:

Contexts where speed matters, but mistakes are costly.

I help ambitious companies turn vision into impactful products by contributing to their high-growth, increasing their revenue, and accelerating learning cycles. Working across B2B and B2C, with a preference for products where users are also customers.

My approach is simple: clarity over complexity.

Understanding what truly drives user behavior and business outcomes. Aligning both. Delivering solutions that are creative & feasible, with a strong focus on results.

I use genAI tools to build and ship functional prototypes to put in users’ hands early, reduce feedback loops, and accelerate decision-making.
