I still remain optimistic about this companies prospects. However, my single greatest concern is that when the time for a capital raise arrives, the amount raised won't be sufficient to keep the company viable until sufficient revenues are made.

At present, the company can only sell 15% more shares.
At present the share value is such that a 15% placement would not raise very much money.

I am assuming that the company thinks there will be sufficient progress between now and then to raise the share price, but this cannot be guaranteed.
Another option would be to take out a loan to last until sufficient revenues are made.

To be honest, I couldn't in good conscience invest any further in this company until I am sure that the company has some contingencies planned in case the share price remains low at the time of capital raise.

I've asked the company if this is the case and, if so, what contingencies they have in place. I'll let you know how they respond.
