Gong

gong.io
Gong is a revenue intelligence company founded in 2015 by two Israeli entrepreneurs, which records and analyses every customer conversation a sales team has across calls, video meetings and email. Rather than relying on what representatives type into a customer relationship system, it derives pipeline health, deal risk and coaching signals directly from what was actually said, which is what made the category credible to sales leaders. Headquartered in San Francisco with research in Israel, the company sells to thousands of business-to-business sales organisations and has extended from conversation analysis into forecasting, prospecting workflows and autonomous sales agents.
