VC Red Flags - New tool

Curious: what red flags have people found trigger VCs to say no? The one I hear the most in deep tech is, "You're too early." But there are scores of others.

I've put together a tool to help founders identify some of the big ones I've come across. You can check it out here: https://www.deeptechdirt.com/assessments/red-flag

What am I missing? What have I called a red flag that you think isn't that big of a deal for a founder?
