I signed with a big one with great terms a year or so ago, a week into I had major regrets, for a few weeks I would ask/tell my "manager" about some big ideas and how to work together and be a team, but it was always crickets on the other end. But I was doing this as a full-time living and these MCNs often don't realize this is your 'baby', this is your livelihood. It's what we think of 24/7 and to them it's just another channel. So I asked to leave and thankfully they were good enough to let me go back to being independent. No one will grow or care about your channel as much as you, it's up to you, they don't really offer anything you can't get as an independent (premium ads are pretty much a farce), you can get your own brand deals and there are brand agencies to work with too if you'd like, you can do your own collabs, sell your own merch (lots of companies will do it all for you nowadays), and if you study all the stuff YouTube offers as resources to grow and strategize your channel, you'll know more than your manager just from what you immerse yourself in with resources on the web. That's not to say MCNs can't be beneficial for some creators, but it's more about your disposition and whether you feel independent or want to at least 'feel' part of a team whether it's a placebo effect or not. If you go in as a big channel, already know your stuff, negotiate 100% Adsense pass-thru so the MCNs motivation is not to take your earnings, but to share branding and other opportunities with you as a win-win, know what you're after, etc., the resources of a big MCN 'could' be of benefit. But there's a lot of fine print in those contracts and they aren't in your favor. And with so much in flux, I don't want to lock down into a restrictive contract and lose some potential opportunities. With MCNs everything pretty much has to go through them. We do other platforms too, including mobile rewards videos, that we couldn't just say "yes" if we were with an MCN, we'd have to run it through them and most likely 'share' the revenue. Same when brands contact you to work with you, you don't have the freedom to go with the flow spontaneously, you have pages and pages of fine print in a contract to be concerned with. I'm a proponent of getting it done independently, you have everything you need to go huge. I'm also anti-huge paragraphs, which I seem to quickly type frequently, ha ha!
