Want advice on your startup? Come to Silicon Valley and sit in the seats occupied by the founders of Pinterest, Yelp, LinkedIn and Skype, among others, and get advice on your startup or startup idea from two partners at one of the Valley's oldest venture capital firms, Bessemer Venture Partners.

If they don't warm to your idea, don't worry, you're in good company. Over the course of their history, they did pass on investments in Apple, FedEx, eBay and Google, instead investing in a wig company, a french-fry company, and the Lahaina, Ka'anapali & Pacific Railroad.

But okay, they had a few winners - and not just the tech firms in the first paragraph, but also Staples, Sports Authority and Blue Nile.

Surely you could use their advice as well?
