I recently hacked together a manual MVP to test demand for a privacy service (to separate your phone numbers in the same way you can separate your email addresses).
I want to find my first 10 users for it.
I feel I am too early to post on ProductHunt, reddit etc. because I couldn't handle a ton of inbound interest. But equally I need to find a way to get it into the hands of at least 10 people who I don't know in order to understand what to build and focus my (very limited) coding skills on working on the right thing.
Should I approach this in a different way? How have you handled a situation like this before?
How about reaching out for a few people on Twitter? Send them a DM or just hit a reply to one of their tweets.
Without giving access to everyone, you can also post your product here: https://www.reddit.com/r/alphaandbetausers/
I think it's also great to do some early functional testing with someone you know. Just to see if everything works as it should.
