Flex-office startup Industrious has nabbed $80 million in Series D funding, with investments from landlord-partners, Fifth Wall Capital, Equinox, and others. Industrious is up to 80 locations in 45 cities since launching in 2013, and has raised $222 million overall. The company is inking more management partnerships with landlords, where it designs and operates an office and its amenities, but doesn't pay a traditional lease. Its CEO said that's key to turning profitable.
