Overview
Raf Mertens founded CrazyGames in 2013 while studying computer science at Stanford. He identified an opportunity when Flash gaming was declining and major platforms like Miniclip and Kongregate pivoted to mobile, leaving a large audience without accessible browser-based games. His brother Tomas co-founded the company initially but left in 2015 to pursue other projects.
CrazyGames operates on an ad-supported model, monetizing through programmatic advertising and in-game purchases via a partnership with Xsolla. The company grew organically for nearly a decade, achieving profitability early and reinvesting revenues to expand the catalog and improve the platform. Year-over-year growth consistently exceeded 100% during the bootstrapped period.
In September 2023, CrazyGames raised its first external capital in an undisclosed venture round led by Belgian growth equity firm Smartfin. By 2024, the platform had reached approximately 35 million monthly active users and facilitated over 300 million gameplays per month across action, puzzle, driving, and multiplayer genres. The company joined the incubator Start it @KBC in 2017.

In the news
- Last week, around 60 of us descended on Leuven from every corner of the map for our latest team week. Cue five days of the good stuff: big ideas, hackathons, and raising a glass to 60 million monthly players. There was ice sculpting. There was a beluga. There was Ziggy. And a lot of exciting plans for 2026-27, for the millions of players and thousands of devs we hold dear. We were Leuven it. (sorry, not sorry) 💜
- One more from the Gamescom afterglow. 💜 Right before the show kicked off, our VP of Partnerships Rafael Morgan handed Imagine Island the PocketGamer.biz Best Web Game of the Year award. The team behind it? Magic Potion Games featuring some of the original Club Penguin creators, back with a new world for players to get lost in. And it's exclusively available on CrazyGames. 👀
- You tell 'em Rafael Morgan! 💜 Gamescom then: "Why web?" Gamescom now: "How fast can I get my game on CrazyGames?"
- Thank you to all our partners and our tireless CrazyGames team for making this gamescom a blast 👏👏👏
- We owe you a coffee gamescom. ☕ Our new brand, out in the wild for the first time. It landed. A booth that never emptied. Thank you. Ziggy is asleep. We should probably join him. Until next year! 💜 #Gamescom
- Just one of our many gamescom highlights (we'll share more next week)... The Best Web Game award (sponsored by us) went to Imagine Island and the Magic Potion Games team! Have you played it on CrazyGames yet?
- Visit our booth and unleash your crazy genius with us at #gamescom2026. 17 of us are heading to Köln (yes, we really love gamescom) next week. Product, mobile, partnerships, marketing, publishing, finance... catch your breath. If you're building for the web, thinking about the web, or just curious about how 60 million players a month found their way onto CrazyGames, come say hi. Hall 4.1, Belgium Booth. Ingmar, Rafa, Dan, Milica, Yusuf, Lada, and the rest of the crew will be waiting. Ziggy too... 👀
- The perks of remote work. We hope your Monday is going as well as Ziggy's. 🌴
