I think the presentation does an amazing job informing entrepreneurs how to sell to companies once they're in your sales pipeline. How do you get their attention in the first place? I asked Bill Campbell and Ben Horowitz this question at an entrepreneurship forum and they responded press and business connections. I imagine that SEO, search marketing, conferences, trade shows, print ads, and viral marketing could be helpful. Has anyone had success using other marketing methods to sell to large companies?
