(Editor’s note: Niel Robertson is the founder and CEO of Trada. He submitted this story to VentureBeat.) I’ve been building venture-backed businesses for over 11 years now.

Almost all problems (and most opportunities) come from understanding how to take advantage of these functions – rather than fight against them.

With a bifurcated distribution you will have to sell differently. eBay provides a different example. Highcharts - Interactive JavaScript charts for your webpage. Use Gmail and Google Docs to budget.
