PREUNINGER BROTHERS BUY BACK MANAGEMENT DYNAMICS FROM CELARIX

PREUNINGER BROTHERS BUY BACK MANAGEMENT DYNAMICS FROM CELARIX    Jim Preuninger and John Preuninger, two brothers who in 1990 founded Management Dynamics, a provider of tariff and contract management systems, have bought back the company from Celarix Inc., a builder of online business networks.
   The Preuningers participated in funding the buyback along with Cross Atlantic Capital Partners, in Radnor, Pa.; the New Jersey Technology Council Venture Fund, in Mt. Laurel, N.J., and the Megunticook Fund in Boston.
   Although the terms of the buyout were not given, the partners said Monday they had provided an additional $6.7 million in financing for Management Dynamics to expand product development and penetrate new markets.
   “The buyout of Management Dynamics provides us with the opportunity to operate as an independent company again,” said Jim Preuninger.
   MD’s flagship product is RateExplorerT, which produces calculable service contracts for reckoning freight totals.
   Glenn Rieger, founder and president of Cross Atlantic Capital Partners, said the buyout was “an opportunity to invest … at a time when new venture capital deals are very rare.”
