I continued to think about this a bit..

Do people really have this problem though? And can you reach these people at scale?

So (cold) emailing, asking people at meetups/Twitter/..., reaching out to old employers maybe etc. to figure out if "they" have a similar idea about the "problem" as I do and would be interested in a service to solve that problem right?

I would think this is easier when I have a simple MVP to demonstrate what I have in mind. Am I wrong with this or should I prepare to give a quick demo?
