NZ Entrepreneurs

After seeing Posse founder Rebekah Campbell interviewed on the evening news, I wanted an excuse to talk to her. I registered the NZ Entrepreneurs domain that night, emailed her, and landed an interview within the week to ask all of my questions. It began a long series of interviews including Rod Drury (several times), Vaughan Rowsell, Morgo founder Jenny Morel, and nearly every other founder in New Zealand. We sold ad space to Chorus within five months of launch, and eventually sold the magazine as a cash-generating asset.
