Michel DevisscherGeneral Manager

We use PieSync to synchronize our Google G Suite account with our CRM and Marketing Automation platform. PieSync was crucial to whether or not we went ahead with our projects. Without PieSync we would have abandoned the projects and all the benefits we’ve gained from it. It was a real situation of “to sync or not to sync".
