Petit Duc
Redesigning a sustainability platform’s digital presence to make complex climate data easier to understand—and easier to trust.
Petit Duc is a digital platform by Merisia that helps event organizers measure, understand, and reduce the carbon emissions associated with participant travel.
My team redesigned the website from the ground up to create a clearer, more trustworthy experience that could help event organizers quickly understand Petit Duc’s value and take the next step.




About the Project
A strong product was being communicated through an unclear experience.
Petit Duc addresses a complex problem: helping event organizers understand and reduce the environmental impact of participant travel
But the existing website made it difficult for a first-time visitor to quickly answer:
What exactly is Petit Duc?
How does it work?
Why should I trust its results?
What does this mean for my organization?
What should I do next?
The challenge wasn't simply to make the website look more modern.

DESIGN GOALS
Clearly communicate Petit Duc's sustainability value proposition
Reduce cognitive friction for first-time visitors exploring the platform
Increase conversion from landing page to booking inquiry
Make environmental data legible and emotionally compelling
Build trust through transparent impact metrics and social proof
RESEARCH AND DISCOVERY
User Research
Before designing the new experience, we wanted to understand how potential users think about sustainability, how they evaluate software like Petit Duc, and where the existing website was creating friction.
What we wanted to learn
We went into research with four main questions:
01 — Understanding the problem
How do event professionals currently think about measuring sustainability and participant travel?
02 — Understanding users
What information do they need before considering a sustainability platform?
03 — Understanding trust
What makes a B2B sustainability product feel credible and trustworthy?
04 — Understanding the existing website
Where do users become confused, and what information feels missing or difficult to find?
Research methods
User interviews with people connected to event planning, sustainability, and business decision-making
Competitive analysis
Review of the existing Petit Duc experience and existing website audit
Information architecture analysis

Research Findings
What we learned
01 — The value proposition needed to be clearer
Users needed to understand what Petit Duc actually does before they could understand why it mattered.
Design implication:
Lead with a simple explanation of the product and its value rather than sustainability terminology.
02 — Trust needed to appear earlier
Because Petit Duc deals with environmental data and business decision-making, users wanted evidence that the platform was legitimate and reliable.
Design implication:
Introduce credibility signals, product visuals, testimonials/case studies, and supporting information earlier in the journey.
03 — Too much technical language created friction
The subject matter is inherently complex, but users shouldn't have to understand carbon-accounting terminology before understanding the product.
Design implication:
Use plain language, progressive disclosure, and visual explanations to make complex information easier to digest.
04 — Users wanted to see the product
A marketing website can explain a product, but showing the product creates a much stronger understanding of what someone is actually getting.
Design implication:
Bring product UI and data visualization into the marketing experience rather than relying primarily on written descriptions.

Moodboard
We created an initial collaborative moodboard, where we collected inspiration from existing websites, including interface patterns, color palettes, typography, imagery, illustration styles, and other visual elements that could inform the redesign.
We then organized our references into four visual directions: illustration-focused, imagery-focused, typography/content-focused, and our team's recommendations. Grouping the inspiration this way helped us identify common visual themes and compare different approaches rather than committing to a direction too early.
After exploring a range of possibilities, we created a second moodboard to narrow down the visual direction with the owner of Petit Duc. We presented a more focused selection of styles and discussed what felt most aligned with the brand, product, and goals for the new website.





DESIGN SYSTEM
From Wireframes to a Visual System
Once the structure was validated, we began exploring the visual direction.
The goal was to create a visual language that felt:
Credible · Sustainable · Modern · Data-driven · Approachable
Rather than relying on generic "green sustainability" visual language, we used the interface itself to communicate the product's data-driven nature.

Creating a reusable visual system allowed us to maintain consistency across the marketing site while giving the product a distinct visual identity. Components were designed to work together across different content types, from educational sections to product screenshots and conversion points.
WIREFRAMING
Low Fidelity Wireframes
With the content hierarchy established, we moved into low-fidelity wireframes to test how information could be prioritized across the experience.
At this stage, the goal wasn't to make the website look polished. It was to answer structural questions:
Is the value proposition immediately understandable?
Does the page tell a logical story?
Are important trust signals appearing at the right moments?
Can users scan rather than read every section?
Does the content naturally lead toward the next action?

Homepage
The homepage was designed as an introduction to Petit Duc's value, gradually moving visitors from understanding the problem → understanding the solution → seeing the product → building trust → taking action.

About / company story
The About experience was redesigned to give visitors more context about Merisia and the people behind Petit Duc, strengthening credibility and helping users understand the broader mission.

From Information Overload to a Clearer Story
The final design wasn't simply a visual refresh. It was the result of translating research insights into a more intentional product story.
Before

The value of Petit Duc was difficult to understand quickly
Information felt dense and required more effort to navigate
Product capabilities were not immediately tangible
Trust and credibility were not established early enough
The experience did not clearly guide users toward the next step
After

The value proposition is introduced immediately
Information is organized around user questions
Product UI demonstrates the experience instead of only describing it
Trust-building content appears throughout the journey
Clear CTAs create a more intentional path toward conversion
A consistent design system creates a more credible and cohesive brand experience
The Key Takeaway
We shifted the website from simply explaining Petit Duc to helping visitors understand, trust, and
engage with the product.
TESTING AND ITERATIONS
Once we had a high-fidelity prototype, we tested the redesigned website with users to understand whether the new experience was clearer and easier to navigate than the original site. We focused on overall comprehension, visual clarity, navigation, and whether users could understand Petit Duc's purpose and value.
What we heard
The experience felt clearer and more straightforward
The visual direction resonated with users
The information was easier to understand
The flow still had opportunities for improvement

FINAL IMPACT
Project Outcome
We delivered a complete high-fidelity redesign of the Petit Duc marketing website that created a clearer connection between the product, its value, and the people it serves.
The redesigned experience:
Clarifies Petit Duc's value proposition
Makes complex sustainability information easier to understand
Builds credibility through product visuals and supporting evidence
Creates a more intentional information hierarchy
Establishes a cohesive and scalable visual system
Gives users clearer pathways toward learning more and engaging with the product
The final prototype gave Petit Duc a stronger foundation for communicating as a credible, approachable, and data-driven sustainability product.
What I Took Away
This project changed how I think about designing for complex products.
My biggest takeaway was when a product deals with complex information, the designer's role isn't to simplify the product itself. It's to create a structure that helps people understand the complexity without becoming overwhelmed.
I also learned the importance of connecting research directly to design decisions. The strongest parts of the final experience came from asking why users were confused, identifying what they needed to build confidence, and then translating those findings into hierarchy, content, flows, and UI.
What I would explore next
Test the redesigned experience with a larger group of event professionals
Measure conversion and engagement after launch
Continue refining the content based on real user behavior
Explore how the marketing experience could connect more directly with the product itself
