Great article. Btw, I wonder why we see so many blogs from SaaS companies revolve around the business side of things. For example Groove does the same thing on it's blog, go into how to run a successful business.
On another note, I've unfortunately stopped using Olark for a completely free service called https://tawk.to. It even came with an Android app, and I just couldn't believe that it was completely free. It was enough for me to completely ditch Olark (even though it was well made), because it was free.
