How about a meal kit company?
Words mean what people who use them intend them to mean, so we end up with things like this:
noun
a new business venture, or a new commercial or industrial project.
adjective
of or relating to the beginning of such a venture or project, especially to an investment made to initiate it

NB: dictionaries are not authoritative sources for living languages, rather they can only be historical records. Thus, words mean what people who use them intend them to mean.
Meal kits are not that revolutionary. Frozen meals have existed for decades, adding some different ingredients and shipping isn't a big innovation on it's own and is more of a standard evolution of food retail.
In my book, a VC money is not a prerequisite for being a startup (although that tends to be how things go these days)
