I'm wondering if it says more about the companies or the people judging them :)
Kidding aside, I'de be surprised if specific words correlated with the probability of success. So there's a good chance this is measuring only if there are key-words that please the reviewers.
I'm sure you've looked at prediction models for individual partners and compared them (or at least considered it, what with days only having 24 hours :)
It'd be fantastic to see you write about the results of that - maybe once the company has launched.
The reason this has me so curious? If the predictive models are not partner-specific, this could indicate that there are very specific things that successful companies/founders say and/or do. Sharing that might or might not mess with the models, but it has a good chance to increase the likelihood of success.
