About CrowdMate
CrowdMate is a free iPhone and Android app for finding live concerts and planning the night with friends. It is built and published by ClairAI SASU, a company registered in Paris, France.
What we build
Most concert apps tell you what is playing. The gap we kept running into was the part that actually decides whether you go: whether anyone you know is going too. CrowdMate puts friend activity on the event page — who is interested, who already has tickets — before you buy, and tells the friends who follow you when you mark a show. From there you can start a crew for that show: a group for the night, with a group chat and a pinned plan for where to meet and when. Keep it private and invite friends with a link, or make it public on the concert page so other people going to the same show can ask to join.
Behind the app is a concert catalog we assemble ourselves, sourced directly from venues rather than resold from a single upstream feed. That is deliberate: the shows you hear about from a friend rather than a listings site are exactly the ones the big aggregators leave out, and a catalog built on someone else's feed would never surface them.
Where we operate
- Live in 105 cities across ten countries: the United States, Canada, the United Kingdom, France, Germany, Spain, the Netherlands, Belgium, Denmark, and Australia.
- 70,000+ upcoming concerts at 1,700+ venues, as of August 2026.
- On the App Store and Google Play. Android shipped in August 2026.
- Free to download and use, with no subscription or in-app purchases.
Coverage changes as we add venues, so the app itself is the authority on where it currently has events.
Who we are
Laurence Mertens
Laurence owes her taste in music to her older brothers, who brought her along to shows from the late 90s on. That is where the love of indie started, and it never left. She lived in Logan Square, Chicago before moving back to Belgium. Always on repeat: Kevin Morby, Aldous Harding, and LCD Soundsystem. She cofounded CrowdMate and leads the venue research behind the app.
Nicolas Mathieu
Nicolas lived in Wicker Park, Chicago before moving to Paris. In both cities he has spent more nights than he can count in small, intimate venues — the kind you hear about from a friend rather than a listings site. He cofounded CrowdMate and builds the product: the iPhone and Android apps, the concert catalog behind them, and the ConcertAPI data platform.
