When did people start paying for your SaaS?
How many times did it take before you got it right? I don't suspect most people get it right on their first go, so what have you taken from your failures and what have been the biggest factors in your success in terms of gaining traction with your SaaS?
In particular, what marketing/promo tactics have served you best?
I think people who are pre-business vastly overestimate the difficulty of getting the first sale and probably vastly underestimate the difficulty of reaching scale. Gail Goodman has a presentation on the Long SaaS Ramp of Death. When you say those words in a group of SaaS entrepreneurs you'll see pained recognition on everybody's faces, even those (of us?) whose businesses are fairly successful. Dear God does figuring out the scalable marketing piece take time. (I've got it figured out for Bingo Card Creator, but have only isolated bits and pieces of the orchestra playing in disjointed fashion for Appointment Reminder.)

I kind of feel like I beat on these drums to death, but organic SEO, AdWords, lifecycle emails, and an optimized first-run experience are sort of my favorite arrows in the quiver for increasing sales. That and a whole lot of just grinding it out.
Also, tie a string around your finger for Rob Walling's presentation from Microconf 2013 where he takes HitTail, a SaaS he acquired, from ~X to ~30X in recurring revenue over the course of a year. (There are numbers in the presentation but I remember him asking us to be circumspect about them.) He goes into month by month detail of what he was doing, and you'll understand the level of sheer frustration involved until hard work and ingenuity starts to reveal "flywheels" (his word for scalable/repeatable acquisition channels). As far as I know, this isn't on the Internet yet, but I expect it will be late this year.
