This was actually the thing that leapt out at me - I don't really have experience of investors except watching Dragon's Den(!) but they've always been super-harsh on those that misrepresent their figures [or at least are caught doing it].

1.4^5 ~= 5.4

Make sure you're being truthful about your figures with yourself - like don't assume you're making a profit just because you're taking revenue, especially not if you're not paying wages yet.
