I would recommend building sharing into the platform and the process in contextual locations (when you signup/save/finish or go to do something else in the app as a popup for example), we also built a referral program into our MVP so users can earn real bitcoin if someone they refer becomes a subscriber to https://BitBank.nz
The referral program helped build links and we should have leveraged adding contextual hints to share and earn because for me the marketing has been a difficult process even harder than building the product and creating machine learning systems...
The ability for people to easily share and a strategy for building links is essential really to spread your product, there is often an initial spike of media attention and press and if your not properly prepared to capitalize on that then your out of luck when the traffic and hype tapers off as it does with the press, one risky thing about releasing an MVP really... although i think releasing an mvp is the way to go.
Do the marketing first. Build it and they will come is bullshit.
That should let you ship early, fail early and not waste a bunch of time. If that doesn’t happen, you know you’re on to something and it’s a fantastic problem to have!
