Sonny Tessier

While your competitors advance, your teams spend their time rebuilding what should already be working.

This loss of efficiency is not inevitable and can be corrected.

I am Sonny Tessier, a Product Designer with over 5 years of experience, specializing in Design Systems for SaaS B2B.

For 2 years, I have been helping early-stage CEOs and scale-up CPOs create products where simplicity, scalability, and collaboration become business assets.

Too many freelance Product Designers forget the real business impact: every initiative must prove its value (reduced Time-to-Market, increased conversion, reduced churn, increased LTV, team productivity).

This is my core business: I think like an entrepreneur: my priority is the ROI of your product investments, for your clients as well as for your teams.

👉 Here are the missions I most often carry out:

1- Creation of MVDS (Minimum Viable Design System) for early-stage products

2- Redesign/optimization of Design Systems in scale-ups

3- Creation of B2B SaaS MVPs (web & mobile)

4- Optimization of products and user journeys, and creation of new user journeys

5- Co-design workshops (Design Thinking, needs & team alignment)

💪 How it works:

1- First contact: 5 questions to understand your context

2- 30-minute discovery call: business framing, KPI definition, then a clear proposal

3- Launch: one-shot or recurring mission, depending on your objectives
