I don't think HBS would be the best dataset to use though: 1. The CTO position probably didn't exist until the 90s so you'd need to restrict your dataset to something more recent 2. HBS doesn't generally attract tech people. All of the people that I know that went to HBS(~20) work in finance/consulting/non-profit. Some came from a tech background. Stanford may be a better choice. That was the vibe I got when I attended MBA info sessions at HBS and Stanford. Columbia had sort of a mix.
