What is an Incubator?

Incubators “typically charge monthly program fees or membership dues in exchange for office/desk space and access to program offerings. Incubators offer programs to member companies that typically include mentoring, education/training, and informal learning opportunities. Incubators also host events to provide networking and learning opportunities for both member companies and the local community. Member companies are usually required to apply to ensure they meet the Incubator’s criteria or mission … Incubators usually have graduation policies based on achievement of agreed-upon milestones, growth metrics or time-based stipulations. Typically, companies join Incubators on a rolling basis and are able to reside in the Incubator for 1-3 years." (InBIA Industry of Terms, Version1.0, Feb. 2017. Pg. 1.)

What is the definition of Cleantech Startups?

“Cleantech Startups” are companies whose primary business meets MassCEC's definition of "clean energy":

“…advanced and applied technologies that significantly reduce or eliminate the use of energy for non-renewable sources, including, but not limited to energy efficiency; demand response; energy conservation and those technologies powered in whole or in part by the sun, wind, water, biomass, alcohol, wood, fuel cells any renewable, non-depletable or recyclable fuel…" MGL c. 23J s.1.

Can my incubator be located outside of the Commonwealth?

Incubator applicants must be located within the Commonwealth.

How long after submitting my IncubateMass application should I expect a response from MassCEC?

It typically takes anywhere from two to three months for MassCEC to make a funding decision. Staff may be in touch with follow-up questions shortly after an application is received.

The Clean Energy Incubator Network is a national network of cleantech incubators, launched by the U.S. Energy Department's National Renewable Energy Laboratory (NREL) and the Electric Power Research Institute (EPRI) in February 2015. The program aims to improve the performance of and provide nationwide coordination among existing and new clean energy business incubators. The network also connects critical industry and energy sector partners to advance clean energy startups and their technologies and serves as a portal for identifying industry best practices. The Clean Energy Incubator Network is currently developing additional resources, such as funding, laboratory and event resources, an evaluation toolkit that specifically guides start ups and a program called SmartIncubationTM​. SmartIncubation is a clean tech business incubator best practice program that will collect metrics from start-ups and incubators and publish the results to identify and recommend best strategies and practices.
