AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
Acta.ai is an AI meeting assistant developed by Agilean Solutions Private Limited, an India-based company. It connects to a user's Google or Microsoft account and calendar, and its agent automatically joins scheduled meetings on Google Meet, Microsoft Teams, and Zoom. After a meeting, Acta.ai records and transcribes the conversation and then analyzes it to generate a concise summary, a list of decisions, and actionable tasks. A distinguishing element is its persona-based approach: the platform offers domain-specific agents oriented toward business functions such as Sales, Engineering, Recruiting, Project Management, Finance, Customer Support, and HR, with the ability to convert discussions into role-appropriate outputs like product requirement notes, ticket-style items, deal briefs, or assessment reports. It also includes an 'Ask Acta' assistant for querying meeting content and provides a Chrome extension. Acta.ai is positioned for cross-functional teams that want meetings translated into structured follow-up work rather than only a raw transcript, and it markets itself around moving from 'what was said' to 'what needs to be done.' The product is actively operating, offering a free trial alongside paid tiers. 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.
