Many aspects of running a startup are incredibly hard. With a startup like InstantCab where our goal is to massively improve a fundamental, real world service like transportation – the challenge of scaling up to serve tens of thousands of drivers and hundreds of thousands of customers is especially hard. At some of our hardest moments, I get asked why I do what I do. The answer is straightforward: I get to lead a remarkably smart team of men and women to solve real problems for thousands of people every day, using technology and empathy, and I get paid to do it. There is really nothing else I can think of doing that would afford me this unique combination of privileges.
