Shortlist FlashRev when outbound teams running high-volume parallel-dialing campaigns matters most, and Substrata when coaching sellers on social dynamics in high-stakes conversations matters most. Run both through a week of actual calls to see which suits your workflow.

AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
FlashRev is the AI go-to-market product from FlashLabs (previously branded FlashIntel) that pairs outbound calling with conversation intelligence for B2B sales teams. Its AI parallel dialer places multiple outbound calls at once and connects reps instantly when a prospect answers, skipping unanswered calls and answering machines so sellers focus on live conversations. The platform records and tracks calls and analyzes each connected conversation in real time, automatically generating intent labels, converting transcripts into concise summaries, and identifying conversation sentiment at scale to support review and coaching. FlashRev positions itself as a broader revenue platform that combines prospecting data, omnichannel engagement across email, SMS, social, and calls, and AI sales-development automation, with the parallel dialer as one component of that suite. It integrates with common CRMs and sales-engagement tools such as Salesforce, HubSpot, Salesloft, and Outreach. The product is live and marketed to outbound and revenue teams; FlashLabs publicly announced an unlimited parallel-dialing capability and continues to develop the platform into 2025 and 2026. 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.
