> Should I too turn every other weekend project into a startup?
They even have a term of it now apparently - Micro startups.
Looking at his own numbers https://indiepa.ge/marclou it's hard to call most of these startups. He's embellishing at best.
As someone who has been involved in a couple startups but not founded one myself, my first impression is that it depends. 16 startups in 2 years is impressive in some sense, but less so if none of them brought it any revenue (I have no idea what the case is with the OP).
if the weekend project has a buy button and a product, yes
Does that qualify as a startup? I'd call that a side project but to each their own.
