Darren Dittrich is CEO of Sell.com, inc., a Dallas-based company he founded in 1999.

Sell.com is an "interactive classifieds" e-commerce solution that models the traditional process of negotiation. The site allows buyers and sellers to communicate one-on-one, and eliminates many of the headaches inherent in online auction communities such as eBay.

Prior to launching Sell.com, Darren founded Emphasys Technologies in 1989. Since 1995, Emphasys has been focusing on Internet solutions, providing hundreds of clients with custom web design, database-driven sites, and managed hosting.

Darren holds a M.S. and B.S. in Computer Science from Virginia Tech.
