Gong

Gong is the world's most-used revenue intelligence platform and the de facto standard for B2B sales teams. It's built by the company of the same name, which turned it into a category of its own, and it's used by thousands of firms from HubSpot to LinkedIn. It's made for sales teams, managers and revenue leaders who want to know what's really happening on calls with customers.

It works by automatically joining scheduled calls or recording phone conversations, transcribing them in near real time and analyzing hundreds of signals in every conversation. It tracks talk ratios, sentiment, objections, competitor mentions and buying signals, and from that it predicts which deals will close. The input is a call or email thread, the output is concrete data and recommendations.
