Lyft board members had discussed replacing current Chief Executive Officer Logan Green, who was not aware of those talks, according to Lyft’s former chief operating officer in a court filing obtained by Reuters on Friday. Ex-COO Travis VanderZanden eventually left Lyft and became vice president of international growth at rival car service Uber. Lyft sued VanderZanden earlier this week, alleging he improperly kept Lyft’s proprietary information after leaving the company, including financial projections.
