Radian
For nearly 50 years, Radian helped lenders say yes to buyers with less than 20 percent down. Now a $1.67 billion bet on Lloyd's insurer Inigo is turning that familiar mortgage specialist into something broader - and changing which risks it wants to keep.
PulteGroup
PulteGroup turned one teenager-built bungalow into a national portfolio of home brands. Its real product is not a floor plan, but a system for matching land, lifestyle and financing to buyers at nearly every stage of adult life.
