Context

Context

Nelio is a curated food delivery marketplace founded in Lyon in 2016, offering high-quality meals from handpicked local artisans, delivered by cargo bike in Lyon and Paris.

After an initial external launch, the product required a stronger in-house design direction to support retention and brand differentiation.

My role

My role

I led product design across mobile and web, collaborating directly with the CEO, CTO, product owners, marketing, and developers. I introduced structured UX processes and aligned design decisions with measurable retention goals.

Experience gaps

Experience gaps

Despite high-quality partners and products, the application struggled to attract and retain the right customer segment.

The experience did not fully reflect the platform’s premium positioning.

Weak premium differentiation

The interface felt interchangeable with mainstream delivery apps, weakening brand perception.

Limited guidance during decision

Users received little contextual support during browsing and checkout. Higher cognitive load, smaller baskets, and fewer repeat orders.

Low contextual relevance

The platform lacked seasonal or event-based content tied to real-life moments. Missed emotional and commercial opportunities, limiting engagement.

Our users

Our users

Our users

To understand real needs beyond assumptions, we ran user interviews with frequent customers and a guerrilla test in the streets of Lyon. This mix of in-depth and spontaneous feedback helped us spot patterns, refine hypotheses, and reveal why someone would (or wouldn’t) choose our app over others.

Why would users choose to buy from our platform
instead of others?

A/B testing

Key design decisions were validated through A/B testing, giving the team objective data to back creative choices. This approach not only secured stakeholder buy-in but also boosted confidence in the final direction.

We tested two ways of handling closed artisans when users selected a “deliver as soon as possible” option, aiming to reduce confusion and friction during the ordering flow.

Option A — Restrictive: closed artisans are hidden or blocked.

Option B — Informative: closed artisans remain visible with clear availability messaging.

I advocated for the informative approach, aligning UX transparency with long-term retention goals.

Integrating design into Core team practices

As the first in-house designer, I introduced collaborative workshops, design thinking methods, and UX-centered improvement cycles.
The result: design became part of the team’s DNA, not just a deliverable.

What we learned

What we learned

This project reinforced three key lessons:

Iterative, business-aligned releases outperform large redesign bets.

Prioritizing and addressing design needs in manageable, focused batches is essential to drive efficient and continuous improvement.

Collaboration goes beyond the core team

Meaningful progress only happens when everyone is involved, not just designers and developers, but also stakeholders, end-users, and teams working on related physical products.

Clarity before perfection

Aiming for pixel-perfect UI components from the start can be counterproductive. Making the interface clear and usable should come first. Refinement can follow once the user need is met.

This is hands down one of my favorite projects, not just for the impact on the product, but for the team journey. We went from “design as decoration” to “design as a driver,” and that transformation was incredibly rewarding.
