The McKinstry Innovation Center recently landed four new tenants at the clean-technology incubator at 850 E. Spokane Falls Blvd., says McKinstry Co., the landlord at the center.

A startup called H-Source has leased 200 square feet of space in which to launch its corporate headquarters, says Murray Walden, H-Source's president.

H-Source is a hospital-to-hospital network that provides a single point-of-contact platform for communication to reduce loss from expiring, overstocked, or unneeded inventories, Walden says. H-Source enables hospitals to achieve flexibility in purchasing and prevent waste from entering landfills, he says.

Two people work at the office, and the company has a sales force of five people throughout the western United States, Walden says.

H-Source also has software partners in the Seattle area, he says.

Another tenant with longtime entrepreneurial roots in Spokane is Tom Simpson, a venture capitalist, angel investor, and former investment banker. Simpson focuses on working closely with emerging companies in the Spokane region to help them grow and become profitable, McKinstry Co. says in a press release.

He is president of the Spokane Angel Alliance, which has invested more than $3.1 million in Spokane-area companies over the last few years.

Simpson also is co-founder of GreenCupboards Inc., an online retailer of eco-friendly products for homes and businesses. In August, GreenCupboards was the first tenant at the McKinstry Innovation Center.

KOA Ventures is another startup that focuses on helping spur entrepreneurial growth in the Spokane area, McKinstry Co. says.

Peter Chase, the company's founder, is the former chairman and co-founder of Purcell Systems, a telecommunication equipment maker.

Another new tenant, Energy + Ecology Innovation Lab, doing business as E2i, specializes in working with emerging technologies in building and site reuse, designing networked building and site components, and integrating energy, water and food systems, McKinstry Co. says.

E2i formed earlier this year as a public-private partnership with McKinstry and the Washington State University Institute for Sustainable Design.

The McKinstry Innovation Center takes up 38,000 square feet of space in the historic 68,000-square-foot Spokane & Inland Empire Railroad Building. McKinstry Co., the Seattle-based construction and energy-efficiency contractor, bought the building in 2010 and redeveloped it to house its Spokane operations and to spur like-minded businesses.
