Money doesn't magically show up at your doorstep even if your product is focused on developers. How do you think SaaS companies are able to hire developers? Do those $350k bay area salaries magically come from nothing? Yes, they often initially fueled by VC dollars, but eventually customer revenues pay for them.
The "anti sales" drivel from engineers on HN who are largely some of the highest paid positions in the world always puzzles me.
It's OKAY to be okay with Sales & Marketing in companies. It isn't some evil function, and discounting it means future entrepreneurs are doomed to fail.
