Having someone feeling passionate about the team or project is the most important screening step. The simple fact that someone in your firm is willing to spend more time finding out more about the project speaks louder than anything else at the early stage of evaluation
Ultimately, a team discussion determines what moves forward. We won’t proceed unless an individual raises his or her hand to lead the effort, because ultimately that individual will have to spend a day a week or more with the company if we make an investment. If there isn’t that individual passion, we won’t proceed.
