2025 has been a defining year for Wiremind. The company turned 10 years alongside the flagship Revenue Management solution, CAYZN. What started with its first deployment at iDTGV in 2015 has grown into a platform used by more than 17 transportation operators across rail, bus, and airline markets.

We thought it is the best time to sit down with our CEO, Colin Girault Matz to understand why CAYZN was created in the first place, how has it evolved over the last ten years, and what is upcoming.

He spoke with us about Revenue Management, real-time optimization, and building tools that actually help analysts think.

What sparked the idea to improve Revenue Management?

It started very simply. When I was a student, I used to take the train between my hometown and my university. Sometimes fares were very high, yet the train was half empty. That disconnect always bothered me. It felt like a kind of injustice — unused capacity on one side, frustrated customers on the other.

Post university, I ended up working at SNCF and especially in the Revenue Management department. Once I was in, I quickly realized how much could be optimized. A lot of the tools and workflows were outdated, sometimes over-engineered, and not really adapted to the reality of the market. There was clearly room to do so much better.

Why did you decide to create CAYZN?

At SNCF, I met Charles Pierre, Co-founder and CTO of Wiremind. Charles had the full-stack technical ability to actually build what was needed. Working with him, I discovered how powerful it is when you combine a clear product concept with the ability to execute technologically.

Suddenly, building a real product (beyond just talking ideas) became possible. That’s when the mission of optimizing trains and capacities truly began, and that’s how CAYZN was born.

What is the core concept of CAYZN?

CAYZN is designed to be the perfect steering tool for Revenue Management analysts.

For analysts, it’s a cockpit that helps them manage their perimeter precisely, extract the maximum value from it, and meet their objectives with confidence. For the company, it becomes a commercial control tower, distributing performance signals throughout the organization.

And ultimately, the goal is very clear: outperform other Revenue Management tools, both in terms of revenue and traffic.

What makes CAYZN different from other RM tools on the market?

The real difference lies in balance.

Revenue Management performance depends heavily on how well an analyst understands the market and specific situations. That understanding comes from visualization and strong UI and UX. If the interface isn’t clear, performance suffers.

At the same time, automation is essential. AI and business rules must complement the analyst’s steering, not replace it. The key is knowing when to automate and when to leave control in human hands.

CAYZN is built around that balance between human insight and intelligent automation.

Technology-wise, what are you most proud of?

CAYZN is the only tool on the market that fully leverages real-time data. It can micro-optimize a flight, train, or bus at any moment of the day, reacting to behavioral changes within seconds.

This is possible because of our scalable architecture: AI flows through engineered data pipelines and fuels the entire ecosystem. In a world where booking peaks and last-minute reservations represent a huge part of the business, reacting in real time isn’t optional, it’s critical.

How is the CAYZN team organized to support this pace of innovation?

We’ve built a very strong, diverse team, and I’m extremely proud of it. We have product teams, QA, data engineering, data science, GenAI specialists, software engineers, and platform engineers all working together.

We operate in nine-week sprints, and during each one we deliver dozens of features. That includes small, delightful quick wins as well as major new modules. The rhythm is intense, but it allows us to keep improving continuously.

Why are users such a central focus for CAYZN?

Revenue Management analysts are experts who care deeply about their work. Over time, we have built a strong user community through webinars, user groups, and daily interactions. We organized our first International User Group in April this year, hosting 80+ attendees over 32+ sessions.

User feedback plays a direct role in shaping the product. Ideas, challenges, and real-world use cases inform our roadmap and help ensure that new features solve practical problems rather than theoretical ones.

Looking ahead, how do you see CAYZN evolving?

The philosophy behind CAYZN remains continuous improvement. The name itself is derived from the Japanese word Kaizen, which means “continuous improvement,” and that mindset continues to guide product development.

We are investing in areas such as ancillary optimization, continuous pricing, network optimization, and the integration of GenAI where it delivers clear value. As markets continue to evolve in speed and complexity, CAYZN will continue to evolve with them.
