Business Insider's Pot Startups in Denver Now Have Their Own Coworking Space provides a nice profile of Green Labs, a Denver coworking space that is focused on the cannabis industry.
The space is targeted at companies and independent workers that provide industry support roles such as financial management, marketing services, etc.
Key quote from a Green Labs blog post:
We provide startup marijuana companies with a collaborative work environment, access to necessary business resources and a forum for ongoing, industry-specific conversation ... and hope to create a centralized space for marijuana professionals to speak and collaborate.
Green Labs is an excellent example of the growing number of vertically oriented coworking spaces/accelerators that focus on a specific industry or type of work.
The growth and success of vertically oriented spaces such as Green Labs is one of the reasons we are forecasting the continued rapid growing of coworking.
