Campbell Lanier III, a veteran entrepreneur and investor, is joining the venture capital firm as senior director.

Kinetic has offices in Atlanta and in Maryland.

Lanier was the original investor in Internet service provider Mindspring, which later was bought by EarthLink.

Earlier in his career, Lanier helped form Interstate Communications (Telecom*USA), which was the fourth largest long-distance carrier in the U.S. MCI acquired the firm in 1990 for $1.2 billion.

“Joining Kinetic Ventures was an easy decision for me,” Lanier said in a statement. “We like the same kinds of investments and we share the same values. They are smart guys who are focused on their business. I like that.”

Most recently Lanier served as chairman of ITC Holding Company. As an investor he has worked with telecom, technology and financial services startups.

Kinetic investments include Broadware, Calix, Cerent, Ciena, Corvis, Metricom, NetCore, Peace Software PlaceWare, and Vertical One.

“We are delighted to have Cam as a member of our team,” said Nelson Chu, managing director of Kinetic Venture’s Atlanta office. “He brings a truly unique and proprietary deal flow to Kinetic Ventures. What’s more, entrepreneurs who have worked with Cam will tell you that his support and involvement in their companies changed the arc of their trajectory and amplified the success they might otherwise have had.”
