My interview with Gabriel Weinberg was originally published Sep-8-2010. He was doing research for what became his fantastic book Traction. We talked for the better part of an hour and a half and I can remember he kept returning in different ways to what was needed to close your first dozen enterprise customers.
He recently reorganized his site and made a fresh start on his blog. I have made some small formatting changes and added links to other blog posts I have written since the interview that elaborate on some of the points that I made.
