How John Giamatteo Started His Career

RealNetworks and Solera Holdings
After leaving Nortel Networks in 2005, Giamatteo joined RealNetworks. The company operated in digital media and internet technology, providing him with an opportunity to expand his experience beyond telecommunications.
He eventually became Chief Operating Officer of RealNetworks in 2008. In April 2010, he moved to Solera Holdings as Chief Operating Officer. Solera provided software and technology services connected to the automotive insurance and claims-processing industries, adding another specialised technology sector to his professional background.
