I still build out everything required to realise the vision, and that usually takes at least months to build. There's an analogy in startups that you should build a great skateboard first if your vision is to build a better car, but I just don't agree. If you have a vision for a better car then you need to deliver a better car, not a skateboard, because, well a skateboard just isn't a car. https://blog.crisp.se/2016/…
If you have a vision for getting people to move from one place to another in a better way, you should build whatever achieve moving people from one place to another in that better way. Getting rid of everything that is not necessary for you to test if you are really getting people from one place to another in a better way.
