Outsell your competition by doing your best work every single time

Real-time guided selling software that helps you have great sales conversations


CRM wasn’t built to help reps sell

A CRM is a system of record, the foundation of your sales stack. But it was not designed to help reps navigate sales conversations, create a business case, and manage multiple deals from start to close.


Reps must rely on ‘ad hoc’ tools 

These note-taking tools do not help reps prep for calls, guide conversations, and sync key insights back to your CRM.  

Ad hoc tools lead to ad-hoc execution.

A negative chain reaction occurs, and it starts with the rep.

Reps don’t consistently ask the right questions or reliably capture key deal insights in CRM.

Sales Managers don't have visibility into deal quality and are forced to coach reps reactively.

VPs don’t have confidence in the pipeline and can’t explain major win/loss drivers.

Which leads to bad outcomes

Meet Costello.

Costello helps you be great in the sales moments that matter. Instead of saying "I'll do better next time," have the right conversation on the call the first time around.

Your reps know what to do. Costello just helps them remember in the moment. Prep for calls, ask timely questions, tell relevant stories, and easily sync key insights back to your CRM.
