Now six months later, I can see who invested as it says as of May 19th...

I also don't see them mentioned in their latest 10Q

When did they start showing them on financial sites, I don't know. If you email IR, maybe they can answer rather than wishing.

Notice they announced great revenues and the market cap moved down

They have 15 institutions and mutual funds.
