Since I started working with post-demo and win loss surveys, I increased my win ratio by 8%! Imagine what that could mean if your average deal size is 50-100k ARR?
In the interest of transparency, I have presented my own client meeting results below (how do you make a sales person feel naked...?) How does showing this help me? It allows me to provide proof of my own performance and abilities, and helps me to improve and sharpen my skills even more through customer feedback! The result: more constructive customer meetings, higher conversion rates, higher revenues (and for me, higher commissions!).
