There are four types of startups: seed, early-stage, later-stage, and growth.
A seed startup is the earliest stage of a company and is typically founders or a co-founder working on an idea. They typically have very little revenue and are oftenbootstrapping their company.
An early-stage startup is a company that has launched and is starting to generate revenue. They typically have a working product, but it is still early days and they are working on refining their business model and growing their user base.
A later-stage startup is a company that has proven its business model and is now focused on scaling. They have a large user base and are growing rapidly.
A growth startup is a company that has reached a level of maturity and is now focused on becoming a large publicly-traded company.
