TEC has been enabling business leaders to outperform since 1957.

TEC was founded by Wisconsin businessman Robert Nourse after his lawn mower company lost a big contract with Montgomery Ward. The failure of his business gave him a chance to implement an idea he had thought about for a long time.

"If other executives had problems like mine, they might see the value of talking them over with their peers," wrote Nourse. He called on several CEO friends and started the first TEC group. The idea proved its worth, and TEC has since grown into a movement that is now embraced by more than 10,000 executives around the world.

The percentage of TEC member companies achieving a moderate to high growth rate is five times greater than the US average.
