Can I just say, I wish I thought of this first? Here's a startup that focuses on connecting people with what they love to do. Of course people will be willing to pay for the opportunity. The business model relies on fundamental human passions and cultivating meaningful relationships. This is what "the daily grind" really should be about: doing what you love with those who believe what you believe. (Simon Sinek, anyone?)
Anyway, I hope it sees more global availability soon. If Lifetramp is really all about doing good for people, I expect it will be quite successful. My only concerns are that A) the price may be inhibitive, and B) the quality of the mentors may be low. Solve those two problems, then integrate with mobile, and I bet it'd be well on its way.
