Three more companies will receive help through Digital Sandbox KC, which provides advice and proof-of-concept funding for area startups.

The three companies—AddVenture, Bulletyn, gr8box—are coming to the Sandbox through a partnership with the University of Missouri-Kansas City’s E-Scholars program for young companies.

“These three exciting companies join the three E-Scholar companies selected in June, and all six show great promise to grow and create new jobs for Kansas City,” said Jeff Shackelford, Digital Sandbox KC’s director. “This was a great example of two Kansas City programs collaborating and together producing higher results.”

What do the new Sandbox companies specialize in?

AddVenture builds short online games that also function as advertising.

Bulletyn is developing a smartphone app that’s designed to replace bulletin boards on college campuses by making it easier to get event listings, want ads and other information.

And gr8box is a subscription service that ships boxes of allergen-free snacks to customers each month.

“We’re honored Digital Sandbox KC has selected gr8box to receive this funding to complete our development,” founder Terri Jordan said.

If you’re a startup interested in Digital Sandbox help, the program is taking applications for companies in Missouri and Olathe. The Sandbox can help young companies pay for some expenses related to prototyping, market validation and testing. For more information, visit this website.
