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.

LevelAI is a SaaS company focused on improving the quality and consistency of customer conversations, particularly in contact centre and support environments. Its product sits around the day to day work of customer facing teams, using conversation data from calls and digital channels to surface what is happening in real interactions, where processes break down, and how teams can coach and improve. The underlying problem it addresses is familiar to any organisation with a large support or sales operation, it is hard to review conversations at scale, hard to spot patterns early, and hard to turn feedback into practical changes without adding more manual work for managers and agents.
