InLighten, a digital media communications company in Clarence, has agreed to acquire land from National Fuel Gas Co. for possible future expansion.

The company is buying 2.4 acres next to its headquarters at 9645 Wehrle Drive, said David Saleh, vice president of new business ventures and general counsel. The sale price was not disclosed; the deal is expected to close in the next 45 days.

InLighten has not yet decided specifically how to use the additional property, which is just east of the facility, Saleh said. “It is to make sure it is available when we are ready.”

InLighten moved to Clarence from Depew in early 2011, after acquiring a 45,000 square foot building that Greatbatch Inc. had leased for its headquarters. The offices are east of Gunnville Road, and just north of Dunn Tire Raceway Park.

InLighten has about 70 employees and said it expects to increase its work force by about 20 percent in the next 18 to 24 months. The company’s digital media lineup includes signage and self-service kiosks.

Location is one of the company’s assets, said Dan Snyder, InLighten’s president and chief executive officer.

“It’s convenient for both air and ground travel and the Clarence community is very attractive to the highly skilled professionals we seek to recruit,” he said in a statement.

InLighten has just relocated two software professionals from the New York City metro area for its newly formed Android development unit, “and the community and surrounding amenities played an important role in their decision to join us,” Snyder said.
