Klaviyo, Inc.
A maker of marketing software that helps online stores send personalized email and SMS campaigns, using customer data pulled from platforms like Shopify to trigger automated messages such as cart-abandonment reminders. Founded in 2012 in Boston by Andrew Bialecki and Ed Hallen, the company takes its name from the Spanish word "clavija," a mountaineering piton — a nod to supporting businesses as they "climb the mountain" of growth.

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: -9.85M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
