> I just offer a very well designed link in bio tools, which is quite rare to find (only a few handful companies are able to pull it off), then maybe there's a chance to capture the market - here the USP will be a well crafted product....but still, I am unsure.

It really depends what a "handful" here means. If there are several companies doing a good job already, it will be tough for you to catch up. If you could find one feature that current tools are bad at, and an audience that feels intense pain about that, then you could potentially get big. Try to own a niche if you are playing catch-up, instead of trying to outcompete the biggest players.
