What Kolet does
Kolet is a Paris-based eSIM platform company founded in January 2024 by three telecom experts led by CEO Eduardo Ronzano. The company operates a consumer mobile application (iOS and Android) and e-commerce website that sell prepaid digital data plans to international travelers, providing connectivity across 190 destinations without physical SIM swapping or roaming fees. The core technical differentiator is a Universal eSIM that is installed once and can be topped up for any country through the app, with the platform aggregating multiple local carriers per destination rather than locking users to a single network. Additional in-app features include data transfer between users, conversion of unused data into Koins (in-app credits), VoIP international calling, regional multi-country plans, and data hotspot sharing.
Kolet's revenue model is prepaid and transactional rather than subscription-based: customers purchase one-time data packages ranging from $3.99 (1 GB) to $33.99 (20 GB), with no auto-renewal. Distribution is hybrid — a self-serve product-led motion through App Store, Google Play, and kolet.com is layered with a channel-led motion through airline partnerships. Named enterprise distribution partners include Air France-KLM Group (including Flying Blue loyalty miles integration via dedicated storefronts), Transavia France (embedded in the airline app), and Philippine Airlines (myPAL eSIM co-brand). A separate Kolet for Business tier targets corporate travelers.
The company has raised approximately €14 million to date across a €5M seed round (January 2024) and a €9M Series A led by Daphni in June 2025, with participation from ex-Expedia executive Peter Kern and ex-Apple executive Jon Gieselman. The team is small (15 self-reported employees), the company is B Corp certified, and it claims over 500,000 cumulative users with 4.9/5 app store ratings. The Privacy Policy references Ody SAS as the operating entity, though Kolet is the primary trade name.
