I just found a great source of market research in a unexpected place and you probably can take advantage of it too
So, I just discovered a great source of market research at of all places my library. Now, not all libraries have access to the same databases, but thankfully a library in my state let me get a library card. The market research database that I found is called Reference USA. I've been really stuck when it comes to trying to find a large and growing market, but hopefully this new information source can help. If anyone has used it before or wants to learn with me I'd love to hear from you. Also, if any Indie Hackers here live in PA you can get a library card at freelibrary.org like I did.
County and city libraries will have different access. Get a card from both. There's even some libraries which have access to a leads database. you can search by business category and find names of businesses, locations, and phone numbers.
I agree with you completely and that's exactly what I did. :) Have you used any of those tools to do market research?
The county I live in and the counties surrounding have some program that lets people get library cards. So, I have two library cards. I haven't used them for accessing different programs. However, they do come in hand when borrowing digital audiobooks. You can have twice as many out essentially and since they are digital you just download them - never have to drive anywhere.
