WILLIAMSTOWN -- A Williamstown native who operates a syndicated radio talk show in Florida has sold his software company for $5 million.

Phil Grande said he sold Spot Link Inc., which develops online trading software, to Florida entrepreneurs Charles E. Gitler III and Donald W. Cogswell.

Gitler is the co-founder of the Money Show, the leading producer of investment advice shows and trading expos. Cogswell is a software developer whose clients include Las Vegas casinos and cruise lines.

Grande, who is 69, said he sold the company because he is planning to retire. But he said he will continue to host "Phil’s Gang," a nationally syndicated radio talk show that is based out of Sarasota, Fla. The show is broadcast in several major markets that are located mostly in the western and southern United States, Grande said.

"We do investment and political talk and everyday national stuff," Grande said.

Spot Link Inc., which helped sponsor Grande’s show, develops online products to invest and trade. Grande said he also marketed Spot Link’s products through his radio show. Grande founded Spot Link with his wife and business partner, Marta, around eight years ago. Grande will remain on Spot Link’s board of directors.

Grande and his brother Stephen, who lives in Williamstown, were well-known professional skiers who grew up in North Adams. Phil Grande later developed land and owned the Grande Oil Co., which was sold to O’Connell Oil.
