Founders should seek revenue when it suits their business and aim to become default alive, while recognizing that the right metrics depend on the company and its market. He discusses how innovation spans both adapting proven models to local markets and developing new platforms, with areas such as telehealth and smarter software gaining momentum. He also expects remote YC participation to continue in a hybrid form, particularly because it makes the program more accessible to founders outside the Bay Area.
