Xometry, Inc.
A maker of custom parts on demand, Xometry runs an online marketplace where engineers upload 3D CAD files and get instant quotes for CNC machining, 3D printing, sheet metal, and injection molding, then a network of vetted factories fills the order. Founded in 2013 by Randy Altschuler and Laurence Zuriff as NextLine Manufacturing, it rebranded to Xometry in 2015 — a mashup of "geometry" and the techy "X" — and later bought Thomas, the company behind the industrial directory Thomasnet. Its AI quoting engine analyzes a part's geometry against millions of data points to price it in seconds.

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 5 years: -1.44M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
