CallCoach is a sales rehearsal tool that allows users to practice their sales calls with an AI prospect. The tool works by first having the user describe the call, including the industry, role, and potential objections. The user then has a conversation with the AI prospect, who will interrupt, stall, and push back in a realistic way. After the call, the user receives a score and feedback on their performance, including the moments where the call turned. The tool also allows users to replay their calls, identify areas for improvement, and track their progress over time.
