As someone who worked as a CTO at what I like to call a "zombie" startup I agree with the poster above me, and it hurts just to recollect the history. You can keep this shit up indefinitely. We're in a weird environment where, with enough endurance, a startup, even one with a miserable high touch sales cycle and poor business model, can live month to month like some sort of crime family looking for the next big score.
If you go this route you'll score a contract or two, and you'll think you're growing. You'll hire on a brilliant employee and then fire them a few months later when the money dries up. Your heart will break. Your workload will increase.
You'll start leaning on contractors because FTEs need consistent revenue, and your shit investors insist on offshore labour because they don't know any better. Contractors suck and their code sucks unless supervised, so you'll decide to do it yourself. Your investors will get unhappy and your partner will find another naive low tier investor to buy them out and start the cycle over. Your share in the company will drop each time you do this.
Your counterpart will spend 1/3rd of their time appeasing the investors and the other 2/3rds attempting to be a top shelf B2B sales exec / account manager which they are not. They will get absolutely abused in the sales cycle and concede to shit they shouldn't. You will continue to burn the candle at both ends like a good technical leader in a crisis and then burn out, believing the entire time that technical superiority alone will win the day.
I'm painting a really bleak picture here, but only because I got out after three years of this when I finally realized the nature of the endless cycle of a cockroach startup. The company I worked for is still going, against all odds. Fuck maybe they go forever. I know people who still work there, and from all accounts it's an endless groundhog day of zero growth and pain.
Don't be that startup, if the business model is in peril this early on don't extend the pain, just pull the ripcord and, above all else, try to learn from the experience.
