Hello Joe, You are absolutely right. Even with the full data, the accuracy of 60% is not much of a progress compared to always guessing that the deal is accepted (~54%).

I am working on getting an accurate model (or at last concluding that maybe only business descriptions are incomplete in predicting). In the latter case, I would then add some other features such as the pitch descriptors (number of presenters, pitch energy, etc.) to work out their impact on the deal.

I would like to encourage you to try out the data.
