You don't know which one is the best idea, so just pick one you most want to finish and build it. Market it. And if it doesn't work pivot or move on to the next idea.
The way I look at it is you build ideas into products and sell those products. Always charge. That way it is relatively easy to turn a small, but meaningful profit. Then, keep building products until you find a "hit".
Even if you don't get to your home run you have some nice cash flow so you can keep doing what you love.
Think of yourself as a band. You love making and performing music. The first record might not be a hit but you keep making music until you come up with something that resonates. Your startup is a band. Keep cranking out albums until something resonates.
I hear so many people saying "just build it". Do these people have so much time in their lives that what they build is irrelevant because they will have time to build everything anyway?
Time is a precious resource to me and if I must build something, I'd rather increase my chances of success by picking the one people need more.
You can do a fair bit of work up front to get a pretty good idea though I think. At least about which of them don't stand a chance. People just don't like doing it, including me, because it's hard.
I have gotten opinions both ways.
People who do not want to critique an idea until they see something they can lay their hands on aka demo.
And the other side where people who want to make sure the idea has market before they write a single line of code.
I am not sure which one works.
Being a coder and as someone who tends to code before evaluating, I would like to know specifics on how to do evaluation before execution.
If a prototype is trivial to build then absolutely. But I don't think there's ever an excuse for not going out and asking people who might have these problems some good questions. "Would you pay for this?" being one of them.
You don't need to build all of them and could still see which one people would buy. You could make 5 websites with some decent SEO, set up a little pitch/video for each application with a download button and see how many people click download on each. You just have an error message when they click download saying sorry, the product is currently unavailable. But you collect the data and see which one wins. Also you could have a comments/suggestion on each to let customers tell you if you're close but they really want something else.
One at a time.
Until you win.
