I often wonder why they don't do some shopping around for corporate sponsors/advertisers in addition to the folks on their Patreon sponsor $500 tier. Seems to me like it'd be an easy way to expand their cash flow a bit and grow things out more without compromising their content. Get the right deals and you could be looking at a very substantial boost to their monthly budgets. Are they just intent on Patreon being their only direct funding source?
A possible problem with this is that some people will stop their patronage if they do something like this. It's the same as the reactions to kickstarted games that afterwards were funded by a big publisher or kickstarted games that were put on the site by big publishers. Not everybody agrees with doing it like that.
The other (and probably bigger) problem is, how do you differentiate between those sponsor tiers and make it so that both of those tiers still want to invest?
Do you put the corporate sponsors (who fund more) bigger on your website? Do they appear on more videos?
At the moment the difference is that you appear on a show that's every week or once per 2 weeks, but with corporate sponsors like that you should at least feature them on both or so.
But is that enough for them to not just pay the $500 tier? What extras do they get over the $500 tier that doesn't upset the people paying $500 per month?
I am not sure if there is an easy solution for this.
That said, I wouldn't mind it myself if the way those corporate sponsors are shown is not too obnoxious and maybe they can find a way to work it out so most people are happy (but I am not sure how to do this).
edit:
Just to be clear, I don't know anything about marketing and there probably is a way. I just don't think it's as easy as mailing or calling a few bigger companies for their support.
