Nautilus Biotechnology, Inc.
A maker of life-sciences tools that study the human proteome — the vast collection of proteins in the body — by counting individual protein molecules one at a time, a field called proteomics. Its commercial instrument, the Voyager platform, is designed to give researchers a far more complete picture of proteins than older methods, opening doors for drug discovery and diagnostics. Founded in 2016 by Sujal Patel, the entrepreneur behind the storage company Isilon Systems, and Stanford scientist Parag Mallick, the firm borrowed its name from Jules Verne's Nautilus submarine — a nod to its mission of exploring hidden "treasures" deep within biology.

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: -4.97M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
