> Mark Ranalli is the founder, president and CEO of BioSqueeze Inc., a Butte, Montana company that uses biomineralization - natural soil bacteria that grow limestone - to seal microscopic leaks in oil and gas wells and stop fugitive methane. A serial entrepreneur who previously built and led companies in publishing and telecommunications with workforces topping 700, he holds an electrical engineering and computer science degree from Stanford and an MBA from Dartmouth's Tuck School, and has served as a business-school dean.
