Backblaze, Inc.
A cloud storage and backup company whose platform holds over a trillion files, it sells two main services: B2 Cloud Storage for apps and AI workloads, and Computer Backup for automatically backing up people's devices. It started in 2007 in a one-bedroom Palo Alto apartment when the founders wanted to stop losing data, and it famously built and open-sourced its own cheap "Storage Pod" servers instead of buying pricey equipment. The founders even filmed early promo videos using actual flamethrowers, a theme that still echoes in its "Flamethrower" startup program.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -3.10M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
