Lyft has scaled rapidly to become a successful company, valued at over two billion dollars and recently raising a billion dollars from General Motors. In 2013, passengers might have struggled to get a Lyft on a Friday night due to the limited number of drivers available. To overcome this challenge, Lyft focused on self-onboarding and mentorship to enable rapid scaling. This approach allowed them to increase both driver numbers and passenger demand simultaneously, ultimately breaking through bottlenecks and achieving success.
