Including the latest funding round, the company has so far raised $47.5 million, Chief Executive David King told Reuters in an interview on Monday.
He declined to disclose the company's current valuation.
Founded in 2014, FogHorn is one of the first companies to make software in the little-known area of fog or edge computing that locally analyses data collected from sensors deployed in industrial equipment to increase speed and save costs.
Edge computing eliminates the need for sending the data to the cloud, instead processing the information where it was generated, in milliseconds.
Many industrial companies are deploying sensors or so-called Industrial Internet of Things, which enables machines to talk to each other and detect problems before they occur.
California-based FogHorn said Honeywell Ventures also took part in the latest funding round, joining existing investors March Capital, GE, Dell Technologies Capital, Robert Bosch Venture Capital, Yokogawa and Darling Ventures.
FogHorn's computing engine can run big data analytics and machine learning on devices that have lower processing power.
The company has forged partnerships with Intel, Dell, GE and other technology companies to get its technology integrated in their products.
FogHorn, which has dozens of customers including Saudi Aramco, GE (>> General Electric Company), Dell and Hewlett Packard Enterprise (>> Hewlett Packard Enterprise Co), is in the early revenue generation stage, King said.
