I thought this may be a good place to tell a relevant story.
I created a company with 2 co founders. I quit my day job doing support for a company in a specialized b2b accounting software industry, and started competing with them soon after.
A year of development later and we had some barely working software, and had already snagged our first client by promising them the second part would be done in the next 3 months. We hustled and got it done enough and just keep 1 step ahead of what was needed.
3 years later, we have around 10 clients, and are almost about to make a positive month and start paying off debt we incurred, towards being profitable. We sold shortly after for around 6 million split 3 ways, and had the option of doing what we were for good pay. We had been living off savings and debt for the last three years so that sounded mighty fine.
