The Indie Hacker Podcast with Fexingo: Solo Developers, SaaS Side Projects, and Independent Tech · 2026-06-07 · 10 min
Episode notes
In this episode, Lucas and Luna explore how solo developer Sarah Chen turned a frustration with poorly documented APIs into a SaaS tool called DocBridge that now generates $45K MRR. They break down how she identified the pain point, built a minimum viable product in two weeks using just one API integration, and grew it to over 2,000 paying customers without any marketing spend. They discuss the specific metrics that mattered at each stage — from initial customer interviews to pricing iterations — and what other indie hackers can learn from her approach. A concrete look at how technical founders can find product-market fit in developer tooling. #SoloDeveloper #SaaS #APIDocumentation #ProductMarketFit #Bootstrapping #DeveloperTools #MRR #IndieHacking #NoMarketingSpend #SarahChen #DocBridge #MinimumViableProduct #CustomerInterviews #PricingStrategy #Technology #FexingoBusiness #BusinessPodcast #IndieHackerPodcast Keep every episode free: buymeacoffee.com/fexingo
