Forming a company is the best way to "putting a buffer between you and the business." But you can't just pretend to be a business, you have to be a business. "Being a business" means separating your personal and business records, separating your personal and business bank accounts, treating the business as a real entity, having board meetings, taking board minutes, doing major activities via board resolutions, following "due process." If you don't behave as a real business, you could find yourself in a situation where someone, most commonly someone who is suing your business, can come after you (and your business partners) personally. And then you are going to say "but what about the liability limitation the business provides?" It may not be there for you.
