I often had startups offer me a number of shares with no explanation for the percentage ownership or the number of total shares.

I said I have to value them at zero without more information and they would act all offended when I asked for more (happened at least 3 times).

This suggests to me that founders either don’t understand the mechanics themselves or are preying on lack of financial understanding.

It’s the latter.

Ignorance is a big problem too. One time I had someone offended when I asked if their insurance plan qualified as a high deductible - they didn’t know it was a legal classification and thought I was accusing it of being expensive.

I’m not anti-startup but the VC backed startup culture of the last 10 years or so has been pretty souring.

It's kinda both sometimes haha
