WINN.AI is a real-time AI sales assistant built for sales reps, sales leaders, and revenue operations teams who want consistent execution on customer calls. During a meeting, WINN listens to the conversation and shows the rep, in real time, which playbook topics have been covered and which still need to be addressed, surfacing cues, suggested questions, and battle cards so reps stay on message and handle objections consistently. Sales leaders can encode their playbook and align it to common methodologies such as MEDDIC, MEDDPICC, SPICED, Challenger, and BANT so that the same process is reinforced across the whole team. Beyond live guidance, WINN automates the administrative side of selling: it takes notes, captures structured data from the conversation, updates CRM records including custom fields, and can draft follow-up emails and help with meeting preparation. It integrates with CRM and meeting platforms including Salesforce, HubSpot, Zoom, and Google Meet, syncing captured data automatically to reduce manual entry. WINN.AI is positioned as a revenue execution platform that combines real-time meeting coaching with automated note-taking and CRM hygiene, making it best suited to B2B sales teams that run structured discovery and demo calls.
