Yup just sharing my experience to help others who are so desperate to prove a market and or have the amazing opportunity to make a living building awesome tech by selling their tech to a big behemoth.
The OP says they are trying to show a market for their tech by winning this contract. After meeting with Google... all tech company's came out of the wood work and one .. Black & Decker wanted to become a customer. Though they refused to sign any type of NDA and or IP agreement yet were willing to pay a very small fee. My mentor (guy who created Xbox headphones) at the time said if they don't sign anything forget it. Ultimately I did, yet it was the crushing blow to the SpeakerBlast team and me personally for awhile.
I think the guy I met with is still the head of Chrome Audio, yet his boss at the time Regina Dugan was just in the news. She was heading up Facebook's secretive research lab, Building 8.
Our experience if I was you is to be weary. Google just wanted to see our secret sauce and once revealed kick us to the curb.
They need to pay you or you walk away!
