Why win-loss analysis?

As serial entrepreneurs, Julien, David and Anne-Sophie founded successful startups in various industries. However, they were facing the same problem over and over : « as a B2B company, you lose around 80% of your deals and you don’t know why. Even funnier, you don’t understand the 20% you win either because you are too busy drinking champagne! »
The fact that many companies pay sales & marketing to create a pipe that doesn’t convert well was a huge aberration for them.
At some point they were wondering: What if we stop guessing and start asking our buyers why they are choosing us or not?
They also realized that best B2B companies were giving this practice a name: Win-Loss Analysis!
Despite the significant added value, win-loss analysis is very challenging to scale only with internal resources. So they created a solution that brings to the market a way that makes this process available to everyone. It was the birth of Diffly!
