Nobody dreams of building a laundry app — yet laundry quietly became one of the most durable on-demand businesses out there, with weekly purchase frequency and customers who stay for years. This presentation breaks down why the "simple" laundry app is secretly a brutal engineering challenge, and what it actually takes to build one properly. Across 10 slides, it covers the multi-stage custody chain that separates laundry from ride-hailing, the three business models (aggregator, asset-heavy, hybrid) and how each changes your build, the features that genuinely drive retention versus the ones that can wait, the four interfaces every serious platform needs, a battle-tested tech stack, and honest cost breakdowns from MVP ($25K–40K) to multi-city scale ($70K–90K+). Built for founders and operators evaluating laundry app development — with practical budget rules and the vendor-evaluation lens included.
