Cuadrilla Capital-backed Chartbeat, a content analytics software platform, completed the acquisition of Lineup Systems, an advertising & subscription revenue management software platform, and Tubular Labs, a social video measurement & intelligence software platform. Financial terms were not disclosed. "Our clients increasingly tell us that the silos are collapsing, and teams are working together on a singular goal. These teams need to deeply understand reach, engagement and impact. Adding Lineup and Tubular to the Chartbeat toolkit fully equips our clients' teams to answer every part of the reader journey. We're excited to help our clients reach more readers and grow their business," John Saroff, Chartbeat CEO.
