Hi, I've got this product idea which I've recently started to build:
A SaaS which brings all your cloud storages together, So you can easily surf through all your files on Google Drive, Dropbox etc. at a single place. In addition to this, the users can easily move files between different clouds right from the app and also take advantage of the total combined cloud space they get.
I don't want to build something which won't be used by anyone. Do you think it's useful and you'd use it? or it isn't helpful and doesn't seem like people will be using it?
i saw somebody had built a similar idea with a chrome extension and later they pivoted. Also most of the business user usually uses one provider.
You need to figure out who can be your potential users and ask them. I don't think many indiehackers are among them. This category could be pretty specific.
