As someone who works with a legacy codebase from c. 1990 as well as a more modern codebase [that is still 10 years old], both of which lack unit tests... I work for a healthy business that has annual revenues of about ~4 million in gross per developer. So if we can make code that old work, you can make your stuff work. It just sucks. Tbh, if I was you and you honestly believe growth is too slow for the startup to survive, I'd seriously consider jumping ship and finding a new job. I also second the find better programmers than you and learning from them. Tbh, I tried to avoid that to get greater job security and I think that was a mistake.
