One guy. Five helpers. $30 million a year in revenue. 97% profit margin. Zero UA. 700 million lifetime downloads. The most successful solo developer in mobile gaming history is Swedish and you've probably never heard of him.
Matej Lančarič, Jakub Remiar, and Felix Braberg return with another One Man Wonder episode — this time on Robert Topala (RobTop Games) and Geometry Dash. The game launched in 2013 as a premium $1.99 title, spawned a free-to-play Lite version, and has been compounding ever since. Active users just hit an all-time high of 10 million DAU — double where they were in October last year. Daily revenue is $75K, with 2025 trending toward $27M after a record $33M in 2024.
The most uncomfortable part isn't the revenue. It's that Topala has literally one UA creative running, his entire growth engine is organic, and his profit margin has stayed between 93% and 97% every single year since 2015. He's still in Sweden paying full Swedish tax because he can't be bothered to relocate. The lesson for everyone else? Either build something so good that creators on TikTok and YouTube market it for free for a decade — or accept that you'll never operate at this margin profile.
