edit: I should clarify again based on sibling/nephew comments... I think it's too far off topic to go into this in depth, but clearly running at a loss is expected and appropriate for companies at a certain stage of their growth profile. Even big companies (like Amazon, like someone noted) can do this if they prefer to invest in pursuing large enough growth opportunities out of cash flow vs selling debt or shares. Regardless, the revenue growth has to show up at some point, and spending in sales has to show ROI.
What?
Anyway, Amazon has razor-thin margins on some products but they're not loss making.
For example, Amazon has 'razor thin' margins and is operating at a slight loss. Does anyone really argue that they are not 'Profitable'?
