Bowmark Capital completed the acquisition of Pirum Systems, a London-based provider of post-trade market infrastructure technology for the global securities finance industry, from Five Arrows Principal Investments. Financial terms were not disclosed. “Twelve years of uninterrupted revenue growth is a great testament to Pirum’s management team. Having known the company since 2011, we are delighted to be backing Rajen and his colleagues as they capitalise on the significant opportunities opened up by continued product innovation and regulatory change. We are also delighted to be working with Pirum’s chairman, Donal Smith, and its founder and non-executive director, Rupert Perry, both of whom will continue in their current roles. Previously, Donal was chief executive of Data Explorers when it was backed by Bowmark,” Julian Masters, Bowmark Capital Managing Partner.
