A minimum viable product forces you to find the features that are most important for your product. Prioritizing features and deploying quickly sets a strong foundation for any project.
Quick deployment means you're also able to swiftly introduce your products to your prospective users. Start your customer relationship soon and get their feedback as you introduce new features.
Put the focus on your product's core mechanics and reduce the risk of building features that have a bad market fit. Add features based on the feedback you get, when you get it. Adjust and improve.
