In this episode, Lucas and Luna explore the story of a solo developer who built a SaaS product around a single API integration—specifically, integrating with Stripe to streamline invoicing for freelancers. They discuss the strategic decisions behind choosing a narrow focus, the technical challenges of building on a third-party API, and how this approach led to a lean, profitable business. The episode provides concrete advice for indie hackers considering API-first products, including how to handle rate limits, versioning, and customer onboarding. #SaaS #APIIntegration #Stripe #IndieHacking #SoloDeveloper #Freelancers #Invoicing #Bootstrapping #MRR #API #Technology #Business #FexingoBusiness #BusinessPodcast #IndieHackerPodcast #SaaSProduct #APIFirst #LeanStartup Keep every episode free: buymeacoffee.com/fexingo
