What sets Kolet apart is its B2B2C model, which has gained traction with major travel players like Air France, KLM, Kiwi.com, Exoticca and Wego. These companies integrate Kolet into their customer journeys to enhance connectivity for travellers.
Kolet aims to fill a gap left by traditional telecom providers, who have often neglected the unique needs of travellers.
By offering instant and universal mobile connectivity, Kolet ensures users stay connected as soon as they land—while helping travel brands stay engaged with customers throughout their journey.
This funding will help Kolet focus on three main areas of growth. First it will enhance the mobile app by adding new features tailored for travellers, addressing telecom needs that are often missed by traditional operators.
Second, Kolet plans to drive wider eSIM adoption by launching freemium offers and making the installation process easier for first-time users. Lastly, the company will expand its team by hiring around 10 new tech, product, and business professionals over the next year, both in France and abroad.
Mario Gavira, VP of Global Growth & Brand at Kiwi.com, says: “Kolet has impressed us with their dedication to helping Kiwi.com’s customers stay connected seamlessly while traveling. Their conversion rates are excellent, and we’re excited about the new growth opportunities this solution unlocks.”
In just one year, Kolet has gained over 300,000 travellers and is on pace to hit 1 million users by the end of the year.
“This Series A validates our vision: to build a tech service that truly simplifies travelers’ lives. At Kolet, technology is not an end in itself – it’s a lever for creating a seamless, reassuring, and deeply human experience,” Anne-Carole Cöen, Co-founder & CMO
With this new milestone, Kolet aims to strengthen its position as a leader in global mobile connectivity, while staying true to its core mission of making internet access accessible to everyone.
