Guidewire Software, Inc.
A maker of cloud software that property-and-casualty insurers use to run their daily operations — handling policies, claims, and billing through products like PolicyCenter, ClaimCenter, and BillingCenter. Founded in 2001 by six software-industry veterans, the company takes its name from the thin medical guidewire that clears a safe path for procedures, a nod to guiding insurers through change. Early on, the team drew on an old Chinese "Farmer and His Son" parable to keep perspective through startup ups and downs.

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 year: -232.5K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
