Looking for a contact information of Muse Audio chief engineer - Kevin Halverson

Does this help?  (scroll down)

Thanks a lot! Sent them a request to share Kevin's contact information.

Why would you expect them to share Kevin's contact information? He no longer works at that company and has no obligation to do anything not even answer a quick email. He may choose to make contact but that's his choice he is under no obligation.

 Well, I'm in situation, where I have not much options to chose from, so every opportunity counts. 

May I suggest finding out if there are any forums in which he participates and reaching out for his help. No one should be providing his contact information without his permission. People should have an expectation of privacy or even just to unplug from work.
