To be fair, I’m not sure blatant lying in investor updates alone constitutes fraud. There needs to be harm (or the intent thereof) AFAIK. The other party needs to be using that information to make a decision. If you give me a dollar and then later I tell you I’m actually Beyonce, is that fraud? Or am I just a lying sonofabitch?
If I give you a dollar and you say it’s being spent wisely, Beyonce loves the product, you’re about to land Taylor Swift as pro bono public ambassador… yeah that’s fraud.
It's encouraging future investment on a false pretext. I'd say that's fraud.
Lying in investor update was merely the tip of the iceberg. There was lots more, fabricating customer traction pre-investment, paying oneself back-pay for months spent twiddling thumbs pre-investment (before I was involved), etc.
My lesson from the whole kerfuffle was that investors (at least the ones I’d dealt with) prefer hustle over integrity and execution abilities.
