One of the most underrated metrics to look at:
Your demo request → opportunity conversion rate
Without spending more, you can get more pipeline created just by improving this metric!
Want to find the failure points? Break down request to opp further:
Demo request → Meeting scheduled
Meeting scheduled → Meeting attended
Meeting attended → Opp created
Your breakdown might look different if BDRs meet with a prospect before an AE, if you demo in a second meeting, etc.
Which area of breakdown have you seen the best improvements in?
