When our friend Imran Ahmed approached us to design a T-shirt for his Harvard Business School Class of 2002, 5th-year reunion, it seemed like a sign.

Over the years Imran had talked a lot about Harvard B-school and how eachstudent sat in the sameseat next to the sameperson every day and lessons consisted of case studies wherein a business is researched and analysed; how there were live link-ups with the chief executive of said business (Harvard University has the world's second biggest endowment after the Vatican) and discussion about what the company was doing wrong, how it could improve, etc. This had always sounded familiar to us. After all, we have been sitting next to each other for three years and all our learning has come from discussions. And anyway, starting a business from scratch is like one long case study, only real: real risk, real money, real consequences.
