I am confused about the dates. If they are doing $3.6M revenue run-rate, that means revenues are $300k/month. Why bother wasting the time to raise what amounts to 6 weeks of earnings?

Revenue is Sales
Revenue > net profit
Revenue > cash flow
net profit != cash flow
Edit: I missed the bullet point about their 97% margin. 97%! Probably gross margin, but still...I am in the wrong industry.
