Maybe I missed it, but WHY does your startup have 30 days to live? You ran out of money and have no raise potential? How could your employee and cofounder not know this already?
No raise potential as metrics are nowhere near where they should be. Solid IP and team that might make for a good acquisition, provided investors will OK it (they've rejected one some time ago)
If you give employees 30 day notice, most will look for other jobs and leave. You will then have no hopes in turning the company around.
