I can't remember the name of the bias, but you are not seeing their perspective. The investors might have encountered many techie CEOs who have failed. It is worth considering that this prejudice exists for a reason.

Now, I am not saying it is true, but being a CEO for a start-up requires a bit (lot) of salesmanship. I do not have that gene. A lot of techie people do not have that gene.

On the other hand, at one company I worked with the CEO was so non-techie he had very little credibility. There were times we had to have follow-up meetings with investors without him to have more meaningful conversations.
