Costello helps you answer sales objections in real-time, capture notes, and sync everything to your CRM after a sales call ends.
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.
The extension is designed to work wherever you go. It’s smaller on-screen footprint allows SDRs/BDRs to have it open inside their sales engagement tool or CRM.
It’s available to anyone with a Costello account. Learn more at andcostello.com.
