Sentilla makes technology designed to guard against wasteful IT energy use. The startup's sensors and software detect how much electricity is used by servers, disk drives, and other data-center equipment, then suggest such money-saving measures as switching off idle machines or combining the work of several computers onto one. "By reducing your energy, you're immediately reducing your operating expenses," says Polastre, Sentilla's co-founder and chief technology officer. Sun Microsystems (JAVA) and the Mozilla Foundation, the maker of Firefox, have bought in, as have companies in other energy-intensive industries, such as metal working.
Lessons learned: "You have to adjust your business model as quickly as possible," says Polastre. "A lot of companies aren't able to articulate [return on investment], but that's what people are buying, particularly in the IT space."
