ProtonMedia, a Lansdale company whose software allows for 3-D online training and meetings, says it has completed $2.5 million Series A venture financing.

The privately held firm said this round of financing came from Originate Ventures of Bethlehem; Osage Partners of Bala Cynwyd, and individual investors.

ProtonMedia said it would use the financing to accelerate research and development of a second-generation platform for online collaborating.

The funds also will be used to expand ProtonMedia's sales force.

"We are pleased to complete this initial round of financing, as we work to roll out the next version of ProtoSphere, and build on our profitable model," said Ron Burns, ProtonMedia's chief executive and founder.
