On the other hand-- man, it would really be great to have $500k in the bank to hire some people so we could grow really fast. But we're not there yet-- that would be a bad investment because we're still doing customer development, we're still trying to discover our business, so to speak.
I feel like, if I go down the path of trying to raise money now, I'll be spending a lot of time doing something that doesn't help us discover that business. But if I don't, who knows what things will be like in a while, if it turns out that we really could use that money.
In the end, though, I side on the idea that money can be a nice accelerant, if it is gotten on good terms (terms are more important than valuation) from good people (and how in the hell do you figure out who those people are? I have seen a lot of damage done by investors in my career.)
But at the end of the day, if the company is profitable, you can plow %100 of those profits into growth. If the company isn't profitable, the only way to survive is outside investment.
I don't want my companies future in the hands of other people, so I'm pursuing a highly profitable business that is super capital efficient and doesn't require outside funding to launch.
I strongly recommend others consider this approach as well. Yeah, you might get into YC and then not need this, but if you don't, find a business model that makes you ramen profitable right away.
