Firefighters found Mr. Mundy and Erin Johansen, 26, of Ontario, Canada, on the kitchen floor. A spokeswoman for the Atlanta Fire Department said the cause of the fire had not been determined but that arson had been ruled out. Insurance investigators said the cause was electrical.
Mr. Mundy was every bit as hard-charging as a businessman as he was as a football player and trackman for Ryan, where he still holds a school record.
He was chairman of EzGov, a company that he cofounded with Edward Trimble in 1999. The company, which employs 150, provides Internet software to governments. The technology, which it has sold to more than 60 governments, allows online payment of parking tickets, property taxes, and other governmental fees.
Trimble said that Mr. Mundy was the one who came up with the idea, adding that he had a "mental and physical toughness about him."
"He was a force of nature," Trimble said. "Everyone who knew him would agree that he was, without a doubt, one of the most passionate people on this planet. In difficult situations, Bryan was never one to lose faith, abandon his convictions, or ever doubt himself, much less consider giving up. He lived for challenges."
Before launching EzGov, Mr. Mundy worked for Unisys and was one of the early employees of Citysearch, a firm that developed local Internet guides. He then worked with Trimble on an e-commerce solutions company called InterArch Technologies, serving as its chief strategist.
The son of a retired Philadelphia police officer, Mr. Mundy was a 1982 graduate of Archbishop Ryan High School, where he was a running back in football, captain of the track team who ran the 400 and 800 meters, and vice president of the Student Council. He holds the school record in the 600 yards, an indoor event no longer held, of 1 minute, 13.66 seconds. He also led Ryan's indoor team to the 1982 Catholic League championship.
He began running long before he competed for Ryan. Starting at age 11, he covered his three-mile route delivering The Inquirer in the Northeast by running.
Ed Ulmer, a history teacher and longtime track coach at Ryan, said Mr. Mundy was "super-dedicated" and a "fierce competitor. He had that aggressiveness from football. He was into lifting weights, and he had huge biceps. We used to kid him about flexing them as a way to give people directions."
Mr. Mundy went on to Lehigh University, where he competed in track. He earned a bachelor's degree in accounting in 1986. He received a master's degree in business administration from the University of Georgia in 1995.
Mr. Mundy was a man of many passions. He wanted to climb the highest mountain on each continent, finishing with Mount Everest. He had scaled five of the seven. He also enjoyed a less arduous pursuit: climbing into a cart for a round of golf.
He is survived by his parents, Mary-Ellen and Paul; his grandmother, Alma Heap; brothers Paul and Michael; and a sister, Donna Steinmetz.
