Company Description

When co-founders Lynn Jurich and Ed Fenster first got into the residential solar energy business in 2007 with Sunrun, solar energy was not a mainstream way for homeowners to power their property. But Jurich and Fenster recruited customers by pitching savings, not just sustainability. "You have to explain how customers will save money or get higher quality or performance," Furich told Inc. The company claims that it will help homeowners reduce their electric bill by about 20 percent. Clients don't have to pay for the installation of solar panels upfront--instead, they can pay a fixed monthly fee depending on how much energy the panels produce. In terms of Sunrun's future, Furich and Fenster borrowed a lot of money to get the company up and running, and it still needs to get costs down to become profitable. Note: employee count as of Dec. 31, 2015

Company Description

It hasn't been a great year for high-tech gadget makers, as Fitbit and GoPro can attest. Yet both are financially outperforming other tech companies that went public when they did, according to EY benchmarks, and pursuing a remarkable rate of innovation. Fitbit's success is due to its breaking into a smartwatch market that could amount to $10 billion globally. The San Francisco company, which CEO James Park co-founded with CTO Eric Friedman, has been scooping up rival smartwatch makers and pursuing patents related to more advanced biometrics tracking, such as whether a device wearer is properly hydrated. In December, Fitbit partnered with medical-device maker Medtronic on an app that tracks physical activity and glucose for diabetes patients. "People might perceive us as kind of a nice-to-have," Park told investors this year. "What I'm most excited about is really transforming Fitbit into a must-have." --Victoria Finkle

Company Description

Medical device company Penumbra first turned a profit in 2012, but co-founders Adam Elsesser and Arani Bose waited until 2015 to take their company public, when they knew they had a solid portfolio of products. "We did that very much on purpose, to ensure that the foundation that we had built at the company, not just financially, but culturally, was very strong," Elsesser told Inc. The company currently designs and manufactures medical devices to treat a variety of illnesses, primarily neurovascular diseases and blood clots, and plans to add new products for at least the next decade. But Penumbra's competitors--Boston Scientific and Medtronic, to name a couple--have well-financed research divisions. This could prove challenging to Penumbra's history of innovation. Note: employee count as of Dec. 31, 2015

Company Description

Imprivata, founded by David Ting, is helping business ditch user names and passwords. The company provides its enterprise-level customers with a variety of single sign-on methods--such as fingerprint analysis and smart identification cards--that employees can subsequently use to access various databases more quickly. Imprivata maintains that its authentication technology is secure, but could take a hit if any of its business customers were to experience a security breach. The security company's customers are primarily health care organizations, but Imprivata also works with banks, energy companies, and government organizations, and is exploring other highly regulated industries that it can service in the future. Note: employee count as of Dec. 31, 2015
