Business incubators make it possible to fail fast, fail often.
I'm sorry for paraphrasing. These incubators allow for that to happen. It involves trying an idea, holding meetings and discussing with other people who are also innovating to come up with promising ideas that will produce a change. These incubators make it possible to try these things out at a very acceptable risk level. You don't have to mortgage your life to test out an idea and start a business.
