MentorMob had sprung from the passions—for web development and for online communities—of the company’s co-founders, Kris Chinosorn (CEO) and Vince Leung (COO). The company pursued the ambitious goals of reinventing the way people learn and becoming the world’s utility for learning about anything. The website leveraged a crowdsourcing model for information sharing, teaching, and learning. By enabling participants to learn—and to crowdsource from each other while learning—the site sought to both engage users at different stages of learning and to develop a compelling experience unobtainable without a crowd.

Chinosorn and Leung needed to prioritize in order to achieve the growth and scale needed to become world’s utility for learning. What should they do next to keep MentorMob’s growth on track? What issues should get their greatest attention?
