Butterfly Network, Inc.
A maker of handheld ultrasound devices that plug into a smartphone, Butterfly Network builds its whole-body imaging probes around a semiconductor chip rather than traditional lead-based crystals. Its products include the Butterfly iQ3, iQ+, and Butterfly Move, used by doctors, vets, and health systems. Founded in 2011 by DNA-sequencing pioneer Jonathan Rothberg, the company got its name partly from the butterfly-shaped signal-processing networks his team studied. Its compact probes are famously small enough to fit in a coat pocket.

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 3 years: -2.83M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
