Yev here -> we HAVE to be cash-flow positive since we're not VC-funded. When we started the company it was bootstrapped, so "making enough money to survive" has always been a part of the equation!
But that means you are an unhip "lifestyle business" and obviously if you're profitable, you must be doing something wrong. How do you ever expect to have an enormous exit and make your investors rich?
But your response was quite informative. Backblaze is one of the few smaller tech companies I admire from a business side along with Fog Creek, JetBrains and Base Camp.
(I only noticed it a few weeks ago when I was surprised to see their address was Austin, TX)
