As someone who is officially a UI/UX Designer but plays many roles in a small startup, I agree with you, particularly in the case of very successful startups like Square. Perhaps the reason it isn't more common is that often times it takes an in-house designer or other advocate of design to get the rest of the company on board with good design as a company priority.
