I'd definitely be interested in knowing more about your company, davideous. I have no doubt that not paying commissions
can work for some companies. And getting comfortable with paying commissions to salespeople took me, personally, a really long time. (Too long, from the perspective of being a good CEO and doing what needed to be done to move my company forward.)
The arguments in the Fog Creek post sound right, and really resonate with those of us who are engineering/product people. But they don't match the reality of my own experience. At least for the high-cost, high-touch, long sales cycle stuff that I have the most experience with, the best salespeople all want their compensation to be heavily weighted towards commissions. So if you want to hire the best sales reps -- and, just as with engineers, you really, really want to hire the best -- you have to recognize and understand that preference.
But I'd be happy to be wrong about this! In addition to Fog Creek, I remember reading another blog post about a startup that doesn't pay commissions. Maybe a Foundry Group company: Moz? I can't find that post now, though.
