I'm surprised by the business model. You're providing business management software but monetizing through ads?

I think this means you're trying to earn dominance over the attention of business owners by providing good software for free, and that you expect to be able to charge a premium for well-targeted ads. This might make great sense for landscaping, where there are significant equipment and material costs and those vendors are highly competitive. "Hello Husqvarna, I have 300 users with $10000 of tree work booked in the next week and only one functioning chainsaw" sounds like a pretty good pitch.

It's kinda the long tail version of facebook's business model, serving a business need instead of a social one. Nifty.
