Episode notes
In this episode of The Indie Hacker Podcast, Lucas and Luna dive into the story of a solo developer who built a SaaS product that connects to a major API and reached $10,000 MRR in just 90 days. They break down the specific tactics used: how he identified an underserved niche within an existing platform, built a minimal viable integration in two weeks, and leveraged the API's own documentation and community to acquire his first customers. Lucas explains the numbers behind the rapid growth, including a $29 per month pricing tier and a referral loop that drove his viral coefficient to 0.7. The hosts also discuss the risks of platform dependency and how the solo developer mitigated them by diversifying his feature set and building direct relationships with users. Packed with actionable insights for anyone building a SaaS on top of a third-party API. #API #SaaS #SoloDeveloper #IndieHacker #10KMRR #PlatformDependency #Bootstrapping #ViralGrowth #ReferralProgram #PricingStrategy #Technology #Business #FexingoBusiness #BusinessPodcast #IndieHackerPodcast #SoloDev #SideProject #TechEntrepreneurship Keep every episode free: buymeacoffee.com/fexingo
