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.
Airspeed, formerly known as Glyphic, is a sales conversation intelligence and revenue-team platform that records, transcribes, and analyzes calls and connects them with email and ticket history into a persistent memory of each customer account. It integrates with meeting platforms such as Zoom and Teams to capture conversations, then surfaces key themes, generates pre-call and post-call intelligence, and provides contextual answers about accounts grounded in actual interactions. For coaching, Airspeed identifies coachable moments with specific post-call scorecards, tracks metrics like talk-to-listen ratio against team benchmarks, delivers automated coaching plans before standups, and offers a practice simulator with buyer personas to build specific skills such as pricing-objection handling and champion building. It scores live calls during conversations and tracks rep improvement over time. On the workflow side, Airspeed auto-syncs data to Salesforce, HubSpot, and Outreach, works within Gmail, Outlook, and Slack, and uses agents that detect signals like champion changes or stalled deals to draft outreach for rep approval and maintain CRM hygiene. The company is based in London and New York and rebranded from Glyphic to Airspeed in 2026; it is a live, operating product. Pricing varies by plan. Check the official website for current pricing.
