Successful crowdfunding techniques?

This is a Business question, so this thread is moved to the Games Business and Law forum. @devbot , I recommend you read other recent posts and questions about crowdfunding in https://www.gamedev.net/forums/forum/23-games-business-and-law/​

What are some successful techniques that AAA studios or indie developers use to crowdfund their games?

I don't believe AAA studios use crowdfunding. But if they do, the fact that they already have AAA standing would certainly be a big factor in any success they might have in crowdfunding.

for sure, AAA studios do not use any crowdfunding - they use direct sales methods from platforms for downloading games, in support, like everyone else, they use marketing

people do not understand that a studio or company is an object and in some way does not belong to anyone - or rather, the company belongs to a person or group of persons, and the game - as a software product, belongs to the company, and not to a private person, and when selling a company, everything that belongs to the company also resold together with the company including the game or many games owned by the company

and more often the name "studio" means a more private professional variation of soft development
