If you run any sufficiently large organization, one of the biggest threats to your business is runaway costs. The largest companies can use upwards of thousands of suppliers for everything ranging from software technology to building materials, and how much you spend on all these suppliers can be the determining factor over whether you're profitable or unprofitable.

That's why most large businesses employ procurement specialists – people whose job it is to oversee and negotiate services with outside companies. It's not the sexiest job in the world, but it's incredibly important, and it's the reason why the procurement services industry is worth $6 billion.

Philip Ideson runs a media company that covers this massive industry. After spending 15 years as a procurement specialist himself, he launched The Art of Procurement, a news and information resource that caters to procurement specialists. Over the past seven years, he's built it into a business that's monetized through live events, sponsorships, and consulting.

In our interview, he talked about his motivation to launch the company, how he built his audience, and why he struggled so long to find a viable business model.
