SalesDirector.ai is a revenue data platform that helps B2B sales organizations scale by capturing and delivering intelligent sales data and analytics to the entire revenue stack. We capture email and calendar data from sales rep activity and cross-reference it with CRM data to deliver predictive insights about their pipelines, behavior and customer interactions. These insights are delivered directly to their CRM or can be visualized in their favorite BI tool (such as Tableau, Domo, Google Data Studio, Power BI or even Einstein Analytics). Armed with these predictive insights, sales organizations can accelerate and optimize their opportunity pipelines, increase their win-rates and power their entire revenue stack with reliable, intelligent sales data. SalesDirector.ai is used by leading software, technology and financial services companies like MongoDB, JD Power, Digital Map, Wicresoft and DeltaData.
