I wrote the company profiles myself. I found all kinds of companies with jobs that weren't posted on any other job boards. Growing an initial audience was the easy part for me because my site was very different from other job sites. Monetizing while continuing to grow the site was what killed me. I relied too much on SEO, and one of Google's whims essentially put me out of business. Most of the startups in the space that I saw fail couldn't even get an initial user base.
