This month's Harvard Business Review features a report that looks at the ways start-up founders can go too far, and the imbalance of power between investors and founders. Steve Blank, Adjunct Professor at Stanford University and author of the report, says investors giving are giving up control for the ability to buy into unicorns. This power imbalance can ultimately impact employees, customers, and investors, negatively. Blank says a case study in this situation is what led to the ousting of Uber Founder Travis Kalanick. Now, Uber's deal with Softbank for a multi-billion dollar investment is in jeopardy with a disagreement over Kalanick's role. Historically Google and Facebook are examples when founders realized they needed help to grow into the job, says Blank. The reason this was accomplished was that the balance of power existed between founder and investors, according to Blank.
