LOL - We need historical information back to 2008 - so grant money now won't help unless I can get a time machine too. They're both equally likely to come by...
You're right talking to Folio and LC makes sense. Folio can't release any of that kind of data without LC approval. LC doesn't respond to any requests like that. I've heard similar from large third party platforms (like lendacademy, nsrinvest, etc...).
Given the above - we're trying to see if individual investors might have scraps of data (screenshots or blog comments) with time stamps that we could use.
