How VeryChic accelerates experimentation with PBX

For over 15 years, Verychic has established itself as the leading platform for premium travel flash sales in Europe. Founded in 2011, the brand has established a strong reputation through its expertise in negotiating exclusive hotel partnerships and luxury experiences. Today, it brings together a community of 12 million members and has already helped over 4 million travelers discover new destinations.

A New Experimentation Strategy

With 1.5 million sessions per month and 100% of its revenue generated online, optimizing the customer experience is a major strategic priority for Verychic. By the end of 2024, experimentation was still underused and not fully connected to the company’s broader strategy, mostly limited to UX-focused tests.

• On the marketing side, tests were rare (barely ten per year), and teams were heavily dependent on Product and IT roadmaps.
• On the Product and IT side, priorities centered around managing a complex backlog, technical debt, and compliance — often at the expense of execution speed.

In June 2025, Kameleoon invited Verychic to become one of the first brands to try Prompt-Based Experimentation (PBX). With this new approach, an idea can be turned into a complete test, including variation, targeting, and analysis, in just seconds. What once took half a day can now be done in a single minute: 87% time saved and newfound autonomy for marketing teams.

A Merchandising Banner Generated in Seconds

The marketing team took the initiative with a simple first test: a prompt to highlight specific themes on listing pages. This scenario had already been tested a few months earlier without AI making it a perfect benchmark for comparison.

‍
Within seconds, the test was ready: same targeting, same safeguards, same KPIs. This time, the entire process which used to take two full days of preparation was completed in just 10 minutes. In only a few more minutes, six campaign variations were ready to launch.

The results came quickly: +31% more clicks on promotional banners over the summer, confirming both the effectiveness of the approach and the ease of deployment.

Adding a Search Bar in Full Autonomy

Building on the success of the first merchandising banner test, Verychic took experimentation with PBX one step further. The team decided to add a search bar to the Circuits page — a page originally designed for inspiration. Since more than half of customers already use search on Verychic, the idea was to make it even more accessible.

The prompt was simple: “Add the search bar from the homepage to the bottom of the header on this page (Circuits page).”

In just 10 minutes, the test was ready, no developer resources needed.
Result: +7% increase in visits to the quote request page.

A Refined Test Governance

The accelerated testing pace doesn’t come at the expense of rigor. By adopting PBX, Verychic established the foundations of a clear experimentation governance:

• A quality charter was introduced (supported by the built-in Q&A process in PBX),
• A shared backlog was created across Marketing, Product, and IT.
• Validation criteria were defined to help scale and industrialize successful experiments.

Conclusion

With Prompt-Based Experimentation, Verychic has transformed the way it works — and the benefits are immediate:

• Autonomy: with tests launched directly by the marketing team, free from technical dependencies.
• Speed: as what once took hours now happens in just seconds.
• Efficiency: since each team focuses on its core role — boosting productivity and reducing costs.

But beyond these tangible gains, PBX has also reshaped Verychic’s entire experimentation culture. Success is no longer measured by the number of tests run, but by their real impact on customer experience and business performance.

This mindset now extends across the organization, supported by a shared roadmap and aligned priorities between Marketing, Product, and IT. PBX has enabled Verychic to redefine its standards, empowering faster, more autonomous, and more strategic decision-making.
