Ceribell, Inc.
A maker of a portable EEG headband system that lets doctors quickly detect seizures at the bedside in hospitals and emergency rooms. The device, worn like a headband, records brain activity and uses AI to flag seizure patterns in minutes, replacing bulky traditional EEG setups. The company was founded in 2014 by a Stanford neurologist and an engineer who wanted a faster, simpler way to spot non-convulsive seizures, and it went public in 2023.

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 the last 6 months: -415.2K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
