People, including 'pg, like to point out that "startups" scale and small businesses are structured to take steady income. But those lifestyle "small businesses" can flip a switch at any time and plow investments into any product idea to shoot for the hockey stick curve. They can even do it more than once.

To answer your question more objectively: we are ~4 years older and substantially larger than most of the companies discussed on HN as "startups". But our product team is roughly the same size as (I think) most of the YC'W11's.
