Wiremind, the Paris-based artificial intelligence software company behind the revenue-management systems used by some of Europe's largest rail and air operators, has closed a €35 million funding round — its first external capital since being founded in October 2014.
The round brings three new investors onto the cap table: IronWave (formerly Wendel Growth), Bpifrance Investissement through its Large Venture fund, and Seaya Andromeda. Crucially, co-founders Colin Girault-Matz, the company's chief executive, and Charles Pierre, its chief technology officer, remain majority shareholders and retain control of the business.
Twelve years without outside capital
Wiremind's story is unusual in an era of venture-fuelled software growth. The company was founded by Girault-Matz and Pierre, who first met at SNCF, France's national railway, where they spotted a gap for machine learning-powered tools to help transport operators manage revenue and capacity more effectively.
For more than a decade, the company funded its own expansion from earnings. According to company figures, it has turned a profit every year since launch, grew revenue 67 percent in 2025, and added 23 new customers during the year. It now counts more than 80 clients across passenger transport, air cargo, and live events.
Software that prices the train ticket
The company's flagship product is CAYZN, an AI-first revenue management system for passenger transport operators that, according to Wiremind, has delivered revenue gains of between 5 and 15 percent for adopters. In 2025, CAYZN's annual recurring revenue grew 81 percent year over year.
Wiremind's portfolio has since expanded to PAXONE, an inventory and distribution platform, CARGOSTACK for air cargo management, and EVENTORI, an AI-driven ticketing and revenue management platform for sports clubs and event organisers.
Why take money now
The €35 million will be deployed on two fronts. First, geography: Wiremind plans to deepen its footprint in South America while strengthening its position among transport businesses in the Middle East and Asia-Pacific, building on traction it has already achieved in Europe and North America.
Second, artificial intelligence. Wiremind builds its own machine learning models and optimisation algorithms, and the new funding will expand its research and development team while introducing large language models into the platform — both inside the decision engine that generates pricing recommendations and in tools that simplify how customers interact with the software.
"Today, we're accelerating our efforts given the speed at which the market is adopting artificial intelligence tools," Girault-Matz said in the company's announcement. After twelve years of saying no, the timing is the market's, not the balance sheet's.
