Not sure where you're getting those numbers. I've been a Backblaze customer for 10+ years, and I was contacted about the directed share program. Have not heard about price or volume yet.
Not who you replied to but I got an email October 22nd "Pre-Registration for Potential IPO Directed Share Program
" telling me to express interest, did, then October 28th got an email from Fidelity "Backblaze Directed Share Program - Account Opening Invitation" giving me until the 9th to open a Fidelity brokerage account.
