Growing up poor and hungry tends to turn some people into hustlers. That's how it worked for me.
Then it was just "right place, right time."
First startup was acquired after Series A by a publicly traded company. Second startup was bootstrapped by the founding team of the first startup and was acquired by a publicly traded company. Third startup was acquired after the Series A by a competitor. Fourth startup was acquired after the Series B by a publicly traded company.
I had incredible co-founders and worked with some amazing teams. I only had one bad investor and was lucky enough to work with some incredible board members. But most of all, I had incredible timing and I embraced the grind.
