Substrata is an AI sales coaching and deal intelligence platform that takes a different angle from typical conversation intelligence tools: rather than focusing on transcription and summaries, it analyzes the social and emotional signals beneath sales conversations. Its core function is to model buyer psychology, attitudes, and momentum across interactions to help professional dealmakers understand intent and power dynamics. A central component is SoundWave, a real-time conversational analytics engine that listens to sales calls and analyzes voice tone, pace, pauses, interruptions, and the push-pull of social dynamics, surfacing the why behind what is being said rather than just the words. Substrata applies this signal analysis across conversations and email exchanges to gauge buyer sentiment and engagement, giving sellers and revenue leaders a read on how deals are actually progressing. The platform is aimed at B2B revenue professionals and leaders, and is positioned for smaller and mid-sized dealmaking teams that want behavioral insight into negotiations and high-value conversations. It has been recognized as a high performer across sales coaching, AI sales assistant, conversation intelligence, sales analytics, and revenue operations categories. Pricing varies by plan. Check the official website for current pricing.
