Growth and long term vision or lack of interest in an exit are not mutually exclusive. At any rate, I'd be curious to hear how companies like Mailchimp are doing these types of compensation.
By "growth-oriented," I'm referring to those companies who eschew any profit in deference to further growth (even if they could show reasonable profit at a slighter lower rate of growth). For these companies, they lack the immediate value to works of a profit-sharing plan, which, IMO, is one of the most valuable aspects of it.
