AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
Efficlose is an AI meeting platform that captures, transcribes, and summarizes conversations through a combination of a Chrome extension, a desktop app, and a web platform. Its Chrome extension is positioned as a way to record meetings without a bot joining the call, capturing audio locally in the browser so no extra participant is announced or shown in the meeting; users can choose to capture a single tab, a specific window, or the full screen, and start or stop recording manually rather than relying on calendar triggers. For users who prefer automated joining, the desktop app and platform can connect to a calendar and send a bot to scheduled meetings on Zoom, Microsoft Teams, and Google Meet. Recordings are transcribed automatically with speaker identification, and the platform generates summaries with key decisions, next steps, and assigned action items. It also offers meeting search across past recordings and an AI assistant for querying conversations, plus integrations with business tools such as Salesforce, HubSpot, Slack, and Notion. Efficlose is aimed at teams across sales, customer success, recruiting, engineering, and project management who want flexible recording options and structured meeting outputs synced into their existing tools. Pricing varies by plan. Check the official website for current pricing.

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.
