The following sentence is very not true and quite misleading:
> Similarly, you don’t work on great technology at a startup. .. They are about business model discovery...
If that is true, then why do technology startups exist at all? Isn't discovering business model very much connected to discovering new technologies (new, more efficient ways to solve problems)? In other words, if a technology startup is not planning to invent something, then it not should probably exist in the first place.
It is true there are some Web 2.0 startups which are not about technology at all, but these startups are anyway not looking for great engineers.
