Building a SaaS App With Claude in 8 Hours

Justin Edwards had a hyper-specific problem: he wanted a better way to drill German grammar, but the tool he wanted didn’t exist. So he described it to Claude and, roughly eight hours later, had a working app. In this episode of SaaS That App, Aaron Marchbanks and Justin use Schleifer as a real-world experiment in what happens when AI makes small, niche software ideas cheap and fast enough to build yourself. They get into why this could put pressure on micro-SaaS products, why trust and expertise may become the new moat, where vibe coding stops being safe, and why the same technology could turn thousands of people who never considered themselves founders into software entrepreneurs.  **What You’ll Learn:** - Why AI makes software ideas that were previously too niche or commercially impractical worth building - Why relationships, trust, and expertise may become stronger competitive moats as software itself gets easier to create - Why handling personally identifiable information changes the security equation for AI-built applications - How a product built for "five other people" could uncover a much larger underserved community This podcast is brought to you by Delta Systems, your one-stop shop for front-end, back-end, and full-stack software development. At Delta, Justin and Aaron share the same philosophy when it comes to clients: they treat people like colleagues, not just customers. Maybe that’s why Delta typically spends years working with the same companies: how many software engineering firms can you say that about?
