MyTime raises $9.3M to build mobile-first local business scheduling

The biggest problem is consumer mindshare. Google and Yelp are where consumers go to find small businesses and they've got integrated scheduling capabilities that's either launched or launching. Getting consumers to come directly to you costs a ton of money in marketing and advertising. Just look at how much Angie's List has advertised and how little mindshare they've gained.

The second problem is on the business side. In most of the verticals that it looks like you're addressing, it's typical to use a practice management system which will hold the authoritative calendar. Without integrations to those management systems, you're never going to be accurate in determining availability. Building integrations is a long-tail problem that often involves integrating with archaic software vendors who have no interest in helping.

Sorry for being so negative, but I've seen plenty of scheduling companies jump into the game because they believe that poor UX is the reason no existing player has become dominant when the reality is that it's just a horribly complex problem where every vertical market has different scheduling needs and there's often very little consistency between providers. And even if you nail the technical problems, you've still got the two biggest problems I described above, which will require some serious BizDev and Marketing, which will often be at odds with each other (i.e. no one wants to partner with a company trying to build a consumer destination).
