Episode notes

In this episode of The Indie Hacker Podcast, Lucas and Luna dive into the story of James Chen, a solo developer who built a Slack-native productivity bot called FocusFox. Starting with a simple script to block distracting channels during deep work, James turned it into a paid product that reached $10K MRR in under a year without any marketing spend. We break down how he identified the pain point, leveraged Slack's viral loop inside teams, and priced it at $5 per user per month. Plus, we discuss the challenges of building on a platform that could change its API overnight. If you're a solo dev looking for a distribution channel that's already inside your users' workflow, this episode is for you. #SlackBot #FocusFox #JamesChen #SaaS #IndieHacker #SoloDeveloper #Productivity #MRR #ViralLoop #APIRisk #PlatformDependency #Bootstrapping #Technology #Business #FexingoBusiness #BusinessPodcast #IndieHackerPodcast #SideProject Keep every episode free: buymeacoffee.com/fexingo
