Well, what is the difference between a hobby project and a startup? Is a startup something that brings in money? If so, I am definitely planning to monetize all the 12 startups. Does a startup need someone who works on it full time? If so, I am working on these things full time. These products may be small but they are real products which will have real customers.
You seem pretty sure you'll have real customers.
Yeah, The first app that I am building has a lot of competitors. So, it is not really a question of whether the market is there. I definitely need the confidence If my startups are going to be successful :)
It's more like building 12 startup MVPs, to test the market, in 12 months
