I think it's a combination of: - common sense (you should have a business plan) and - avoiding premature optimization If you can build an unprofitable business that is growing like crazy and has a clear path to profitability (i.e. the fundamentals of the business are not based on unscalable factors), it shouldn't matter so much how close you are to profitability.
