You realize you're responding to a solo founder of a standalone startup that sells
bingo card creation software, right? I have mad respect for Patrick (he's sitting right next to me at the moment), but if you were under the impression that being a Bingo Card Mogul meant Cristal and Rolex watches, uh, no.
How much more credible a testimonial can you get than "I built my business in 5 hours a week, I sell bingo cards to school teachers, and I easily expect to recoup the investment I'm making in KISSmetrics"?
For what it's worth: I sell enterprise software at a price point several orders of magnitude higher than Patrick's, at a company with more employees than most established YC companies, and KISSmetrics isn't worth it for me right now, because I'm simply not prepared to feed it the data it needs or to make the decisions it's expecting me to make.
I don't take it personally that KISSmetrics is pricing me away from paying for it. In fact, I appreciate it; it's preventing me from wasting time.
