He became CEO of Internet Marketing Inc. (IMI), the first web mapping service on the Internet. He also established the Laurel, Maryland-based iAtlas. IAtlas established the first database on businesses on the Internet, compiling information that could be purchased by third-party groups for 5000 dollars. It also established a search engine that enabled casual users to locate businesses in specific locations, the first search engine that was able to do that. Initially relying on a business incubator provided by Doug Humphrey, within a year it had secured three million dollars of venture capital. On August 3, 1999, iAtlas secured a partnership with Ameritech (then the largest telecommunications company in the Midwest), allowing Ameritech's yellow pages search engine to use the iAtlas Registry.

In 2005, he founded the startup company TalkPlus, based in San Mateo, California. TalkPlus serves as a mobile phone service that allows multiple phone lines to be used from a single mobile phone, as well as make calls from an existing landline phone number. The service allowed for new phone lines to be created for as much as one-tenth the cost of creating a new landline. Applications were also seen for use in conjunction with online dating services and online auction sites, to prevent callers related to those services from gaining access to permanent personal or business phone numbers.
