Ask HN: Raising capital when under NDA regarding business agreements?

So our company is raising capital and some of the strong points are our B2B contracts. All these contracts are under NDA, but as business achievements they belong in the pitch. I cannot expect VCs to neither honor verbal confidentiality agreements nor sign NDAs.

What is the industry standard about talking about NDA-ed contracts when pitching to VCs then?

"We have a contract with company we cannot name in a space cannot quite describe that is about something we cannot talk about"?
