I took part in one, made by remute. And it was awesome, but at least one game has to be "famous" otherwise I don't see many people chipping in

How did you find someone who wishes to make such bundle with other developers?

I was contacted by the organizer via email. I guess if you search previous bundles and email the organizers maybe they can have you in mind for their next bundle.

Thanks for the advice :)
