A "boot" in the context of a startup refers to the initial phase of launching a new business. This stage involves developing a business idea, creating a plan, and securing funding. Entrepreneurs often seek to validate their concept through market research and early customer feedback. During the boot phase, founders may work with a small team to build a minimum viable product (MVP) that demonstrates their idea. This process helps attract investors and customers, setting the foundation for future growth. Successful bootstrapping can lead to a sustainable business model without relying heavily on external funding.
