Jumpstart is the perfect starting point to build your new product idea. Skip weeks of development on things like authentication, teams, payments and billing, social login, admin areas, staging, etc, etc. Instead, focus on building and launching your product.
Jumpstart takes away the common features that new SaaS apps all seem to require. With the "standard" features done I'm free to focus on exactly what gives the app value. This makes taking a new product to a usable MVP faster than ever. Highly recommend.
