Mark Scott, CEO of Cello Health, said: “The social listening industry is undergoing a wave of consolidation, and its value is moving from simple brand tracking to creating an ongoing feed of audience insights into organisations.

“Francesco is the ideal person to lead Pulsar during this industry shakeout phase, bringing to the table a mix of excellence in product design, big data, and audience research.”
