What is the first stage of startup development according to Brian Chesky?

According to Brian Chesky, the first stage of startup development is survival. This critical phase is characterized by immense challenges where founders face skepticism, with everyone telling them they're crazy. During this stage, entrepreneurs struggle to raise money, maintain co-founder commitment, and simply keep the venture alive. Chesky emphasizes that startups aren't meant to survive naturally, making persistence crucial. He defines success in this initial phase simply as 'not dying is working on it' - suggesting that continuing to push forward despite obstacles represents achievement. This survival stage forms the foundation upon which all future startup growth depends.
