How a Solo Dev Built a SaaS for a Single YouTube Channel

Episode 23: How a solo developer built a $12,000 MRR SaaS serving exactly one YouTube channel — and why hyper-niche is the new indie hacker strategy. We break down the product (a real-time merch inventory tracker for a 5-million-subscriber creator), the revenue model (a flat $1,200/month retainer plus a 2% rev share on merch sold), and the surprising lesson: the developer didn't build for 'everyone' — he built for one specific customer and scaled from there. Plus, we discuss the risks of customer concentration, the power of deep integration over broad features, and how this approach could be replicated. No-code tools, API-first design, and a founder who treats his single client like a co-founder. #SoloDeveloper #SaaS #IndieHacker #YouTube #NicheMarket #MerchTracking #APIFirst #NoCode #Bootstrapped #SideProject #MRR #CustomerConcentration #CreatorEconomy #RevenueShare #Technology #FexingoBusiness #BusinessPodcast #IndieHackerPodcast Keep every episode free: buymeacoffee.com/fexingo
