Katie Cline never saw herself as an entrepreneur. But when the real estate bubble burst, right after she finished her MBA, she learned from personal experience how to spot a need and fill it. And she learned how to live out her values with each new successful venture. She began her career at Lockheed Martin Aerospace in communications and business development, and then in project management overseeing $15-million projects. An embryo donor, she co-created Prebornkids.com, matching donors to adoptive parents.
