"It's like a high-quality Ikea building in a kit, but it's hurricane strength," says Ann Hand, CEO of Project Frog, a technology-meets-high-design startup. The firm creates low-energy prefab buildings that reduce both cost and waste while optimizing performance for the users inside. Hand -- who spent 20 years at BP, most recently as SVP of global brand marketing and innovation -- says that the VC -- backed Frog approaches buildings as tech platforms: a structure composed of "smart" parts that can be optimized depending on size, use, and location. And because all the parts arrive flat-packed and ready for assembly, what once took two years to build can now go up in less than a month. Hand has helped expand the potential for "Frogs" from schools and parks to the health-care industry and retail structures. She is determined to revolutionize the entire $400 billion U.S. -- commercial-building market. "I won't rest," she says, "until we shake up the industry and attach some guilt to wasteful construction."
