About this episode

Antoine van der Lee discusses building RocketSim and the challenges of indie development.

On the podcast: Antoine shares how he built RocketSim from an internal tool into a thriving business, the challenges of scaling as an indie developer, and the key marketing insights that drove growth—without relying on traditional ads or influencer campaigns. Top Takeaways: ⏱️ Solve time, and they will pay you There are countless solved problems in the world, but if your tool gives developers back their most limited resource—time—the sales pitch writes itself. 🧱 Build what your users ask for, and the trials will follow Releasing the number-one voted feature on a public roadmap is the most reliable way to turn dormant users into active trials. 🐢 Some problems take years to solve Not every technical hurdle can be Googled; sometimes you have to sit on an open issue for two years until your skills grow enough to crack it. 🤝 Embrace your competitors Cross-promoting with competing apps and newsletters actually grows your audience faster than trying to dominate a niche alone. ⛓️ Constraints are a feature, not a bug Going full-time indie can actually hurt productivity if you lose the strict prioritization habits that made you effective when time was scarce.
