Rearden Commerce is looking to add roughly 250 employees to its current 600,

according to a spokeswoman. It remains to be determined how many total personnel will handle account management and sales in travel services, new senior vice president of travel services Andrew McGraw said. According to the former American Express executive, "a lot of the expansion will be in the offers area," a new service based on Rearden's September HomeRun.com acquisition that presents what Rearden calls "highly relevant offers to consumers based on their identities, locations and context." The company is growing its Scottsdale, Ariz., location, where it expects to house half of the new personnel, to support the initiative.
