Technology Review has published an interesting, in-depth article examining the foundation and operations of PayPal, a small company founded in 1998 that now dominates the person-to-person Internet payment industry. Beginning by profiling PayPal’s 26-year-old co-founder and Chief Technology Officer Max Levchin, the article looks at the brain’s behind the company’s anti-fraud task force team, dubbed Igor, how the company has carved out its successful niche, and why credit card companies such as Bank One and Citibank are becoming increasingly anxious about PayPal’s growing number of daily transanctions.
