On some level it's the role of the publisher to pick winners and guide them over the finish line. See for example the hit machine that is Devolver: https://www.devolverdigital.com/games

I'm not an indie dev, but if I was I would happily give up a chunk of my potential profit to be listed on there, knowing the size of the market that says "oh yeah... a Devolver title, I would blind-buy this, it's probably pretty good."
