88: SwiftLee – Antoine van der Lee

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.About Antoine van der Lee:🚀 Indie Developer and Creator of SwiftLee, a platform for iOS developers, and RocketSim, a tool that streamlines testing and simulating apps in Xcode.👋 LinkedIn  🌐 Learn more about RocketSim🎧Learn more about the Going Indie Podcast 📖 Read Antoine’s developer blog at SwiftLeeFollow us on X: Charlie Chapman - @_chuckycRevenueCat - @RevenueCatLaunched - @LaunchedFM Episode Highlights:[0:00] Introduction to Antoine van der Lee and the story behind RocketSim[2:15] How Antoine started in iOS development and his early career journey[5:05] The creation of Swiftly: Antoine's approach to writing and sharing knowledge[7:40] The launch of RocketSim: From an internal tool to a public product[10:12] The challenges of developing a useful Xcode simulator tool[12:31] Antoine's approach to growing RocketSim without focusing on traditional marketing[15:22] The evolution of RocketSim: Expanding features and listening to users[18:05] How Antoine used his blog and newsletter to support RocketSim's growth[21:40] The balance between RocketSim as a product and maintaining a sustainable indie business[24:25] The impact of the App Store: Sales model and challenges[27:11] RocketSim’s transition into enterprise sales and selling to teams[30:03] Hiring for RocketSim: Bringing in the right people to scale without losing focus[33:20] The evolution of the RocketSim website and customer experience improvements[36:05] Antoine's experience with creating a full-time indie business alongside a family[39:00] Dealing with the growth of RocketSim and managing multiple projects at once[42:10] Insights into Antoine’s shift from a full-time job to an indie developer[45:35] The role of personal branding and community connections in RocketSim's success[48:10] The value of networking and connecting with others in the iOS community[51:05] Moving from product development to managing a business[54:01] Reflection on growth, work-life balance, and achieving indie success[56:22] Key takeaways for indie founders and AI product builders today
