Are you bootstrapping your business? Why?

I want to hear from my fellow founders who are boostrapping their ventures. In a world where raising funds, burning cash, chasing exits get all the limelight; bootstrapped founders rarely get attention.

I've personally known several founders who are happily running their $20 - $100K MRR businesses either as solo founders or with a small team and highly profitable.

So my question is: What is your main reason to bootstrap and not chase funding?
