Running a company is like being a good coach, at least that's the way I like to look at it. Herb Brooks (coach of the 1980 US Ice Hockey Team) was known for saying "I'm not looking for the best players, I'm looking for the right ones". Likewise, you can have the 8 best engineers in the world but unless they work well TOGETHER, your company isn't going to go very far at all.
Bottomline: More VCs should pay attention to the entire team--not just the founders--and especially way more than the 5yr business plans, financial models, etc. because these will most likely change a fair amount, the team won't as much. If the brains are there and those brains work well together, you've got a recipe for success.
He seems to have been part of the original founding team and CTO but no mention of him in the past ~1 year.

He's not mentioned in the OP-- which seems to list everyone in the company by name-- nor anywhere on Vidyard's website.
