AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
Akkadu, built by Akkadu Technology, is a platform for breaking down language barriers in live and recorded settings. It listens to a speaker's audio and produces real-time AI live captions and subtitles in more than 90 languages, and can deliver an AI voice translation that voices a speaker's words in another language. Beyond automated transcription and translation, Akkadu also offers remote simultaneous interpretation (RSI), connecting human interpreters to events, plus human live captioning for higher-accuracy needs. It is available as a desktop and web-based application and is designed to work alongside common video conferencing tools such as Zoom, Microsoft Teams, Webex, and Google Meet, as well as on-site and hybrid events. The company states it does not store voice data and gives users control to delete transcripts. Akkadu targets event organizers, conferences, corporate meetings, universities, content creators, and language service providers who need multilingual accessibility. It is offered on a pay-as-you-go hourly model with a free limited demo tier.

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.
