A maker of the nearly invisible teeth-straightening trays known as Invisalign, plus iTero scanners and exocad software that let dentists plan treatment on screen instead of using metal braces. Founded in 1997 by two Stanford business students, the idea grew from co-founder Zia Chishti noticing that a series of custom retainers could gradually move teeth. Its name blends "invisible" and "align," and its trays have treated more than twenty million patients worldwide.
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.
