How a Solo Developer Built a SaaS in Public for 100K Followers

In this episode of The Indie Hacker Podcast, Lucas and Luna explore the 'building in public' movement through the case of a solo developer who grew a Twitter following of 100,000 by live-streaming his SaaS build from scratch, hitting $80,000 in annual recurring revenue within 18 months without any marketing spend. The hosts break down the specific tactics he used—daily transparent revenue screenshots, honest failure posts, and engaging his audience as co-builders—and examine why this approach works better for some niches than others. They also discuss the psychological toll of constant transparency and whether building in public is a sustainable long-term strategy or just a trend. Tune in for a grounded, example-rich conversation about the real costs and rewards of putting your work—and your numbers—on display. #BuildingInPublic #SoloDeveloper #IndieHacker #SaaS #TransparentRevenue #TwitterGrowth #AudienceBuilding #Bootstrapping #ARR #RevenueScreenshots #CommunityBuilding #SoloFounder #NoMarketingSpend #Tech #FexingoBusiness #BusinessPodcast #IndieHackerPodcast #SideProject Keep every episode free: buymeacoffee.com/fexingo
