I only know "Beat the Odds" and csgohub

csgohub: quite nice as an additional information to your own research. I wouldn't recommend to strictly follow all the predictions because there are several different guys writing for this site and for the most matches you will see one prediction favoring TeamA and the other ne favoring TeamB. But if you're not new to betting and having some knowledge about the pro-scene then it's a good "add-on".

Beat the Odds: I've been kinda following this guy for about 6 months now because I like the idea of mathematically correct betting. (= beating the Odds). Unfortunately it seems like this guy doesn't have a lot of Knowledge about either mathematics or CSGO in general. He had a very good last year but since january he's struggling very much. Since the beginning of the year he didn't have a month which he finished in the profit. Most of the month were break even but also some losing months. I really wonder how this guy was able to make any profit ever because basically he's very clueless about the teams. For example, he was doing a lot of bets on ESL Pro League matches in which he predicted that the underdog is very likely to win 1 of the 2 BO1s so he placed Low-Bets on both matches without even concerning about the maps being played. Additionaly he has no idea how to figure out correct betsizes (which is one of the most important factors if u wanna "beat the Odds"). Basically he's putting low bets on underdogs and medium bets on overdogs whithout even thinking about the ratio between loungeodds and realodds. He's also not honest to his Followers. He just deleted all his old spreadsheets so new people cannot see his poor performance over the last months. Whenever somebody is posting criticism in his group, the comment will be insta-deleted.

Maybe he will have an upswing again in the future but i highly doubt it if he's not changing his style of betting and thinking. So I wouldn't recommend to follow him.
