There is a big difference in efficiency across people and startup teams, in terms of what they might achieve in <X> amount of time. A solo founder with no experience as an entrepreneur, little technical prowess, and few useful connections would generally take longer to be successful. For example, look at YC companies' varying degrees of progress at demo day. They usually have at least two founders -- if they are working 80 hours/week, they would roughly be putting in 1,000 hours per founder after 3 months.
