StartupDigest is a guide to the startup technology world that provides insights on high tech startup events. It is curated by Brendan McManus and Chris McCann. The document discusses the concept of a minimum viable product (MVP), which is the simplest version of a product that allows it to be deployed and tested with customers. An MVP should get early feedback, test if there is demand, and prove initial traction before further development. Examples of MVPs include email newsletters, online ads, and basic landing pages. The goal of an MVP is to test hypotheses about problems and solutions through quick, low-cost experiments.
