Does sponscribe work?

I’ve been trying to get sponsors for my channel for a while and wasn’t having much luck, so I recently tried this website called sponscribe, It did help get my channel seen by brands and I started getting a few replies, which is more than before. I’m still not fully sure how it works long term though, so I wanted to ask if anyone else here has used it and whether it’s actually legit or worth sticking with. For me it seems legit but want to know what you guys think.
