Full summary
Have you ever frozen on a cold call? It’s easy to do. Not asking the right questions, stumbling on objections, or forgetting to tell the right customer story can keep you from booking a meeting. In the past, SDR/BDRs had to use Google Docs, Post-It Notes, or pdfs as a back-up plan on calls. Scrolling through docs distracts us from the conversation we’re having at the moment. What if there was a better way? The extension is designed to be used during SDR/BDR calls. It provides a real-time co-pilot that: -Keeps you confident with immediate answers to objections and questions about competitors -Helps you build trust by providing relevant customer stories to tell -Ensures that you earn your buyer's respect by always asking the right questions After a call concludes, the Costello Chrome Extension pushes notes to your CRM, sends a call summary to Slack, and can even create a sales opportunity — all from the push of a button.
