Knovvu Analytics by SESTEK is an enterprise speech-and-text analytics platform that transcribes and analyzes 100% of customer voice and digital interactions for contact centers.
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.
