Edtech startup Citelighter left the Big Apple for Baltimore city in 2013. Now another edtech company is trading New York City for Baltimore.

Three Ring will move its headquarters to an undetermined location in the Inner Harbor in order to “be closer to Maryland’s schools and districts where its mobile application has been adopted,” according to a press release.

“We’re finalizing a space in the Inner Harbor, so we can’t share the address just yet, but it will be a brand new space,” said cofounder Michael Lindsay by e-mail.

The six-person startup, founded in 2011, develops an app that creates “digital files” of students’ work, including papers, tests, video presentations and other material. Some 35,000 teachers across Maryland currently use Three Ring’s app, the company said.

“We’re not sharing revenue yet, but we have strong relationships in multiple Maryland counties,” Lindsay said. Among them: Baltimore, Howard, Harford, Anne Arundel and Frederick counties, as well as Baltimore city.

Right now the startup is buttressed by $1 million in equity funding it finished raising in November 2013, said Lindsay.

“For an education company like ours, being located at the center of Baltimore’s growing edtech ecosystem connects our team with top-tier collaborators and forward-looking school systems poised to integrate new technologies that help students learn,” said Three Ring chief education officer and cofounder Steve Silvius.
