Some get traction, or maybe growth early on, but actual startups don't seem to "make money in a short amount of time"
But overall, I think a startup's job is to validate an idea, then grow. If you can't make money at first, you probably don't have a valid idea. The next phase is pure growth--and I'm sure very few new businesses can make money AND grow at the same time.
Lightning in a bottle is 1-2 months to break-even under the bootstrap scenario. 6-8 months is closer to reasonable depending on cost of living for where someone is living. Anything much beyond that time-frame means something is very, very wrong (or it's a particularly unusual business being formed, requiring years of build time).
Four years to get to a few thousand dollars per month in sales? I don't think so.
I totally agree that it's very easy to get to a few thousand dollars a month in sales. It's getting beyond that which is hard.
How long did it take you to get to a few thousand dollars a month cheez? Out of interest, how far into your career was that?
I'm not sure I'd class getting to a few thousand dollars as "very easy", certainly do-able for a lot of businesses with a few months to a years hard work, but I wouldn't call that "very easy", personally.
The one thing I did right was find the market first, then built a product for that market.
