Federal contracts (USAspending, awards started in the last 180 days)

No contract award starting in the last 180 days was found for a recipient named exactly "Klaviyo, Inc.". Subsidiaries and differently-spelled recipients are not matched — search contracts.

Lobbying (Senate LDA, as client)

No LDA filing posted since October 2025 names "Klaviyo, Inc." as the client. Filings under a subsidiary or trade-association name are not matched — search lobbying.

Companies whose stock was traded by the same people who traded KVYO, by number of filers in common. It shows overlap in public filings and nothing else.

Site built October 22, 2026. Every row in the tables above links to its own filing. To quote a figure, use the Cite button at the top of the page; see how to cite and reuse.

Insiders and their transactions come from SEC EDGAR Form 4 filings for this issuer. Contracts and lobbying are matched by exact normalized name (suffixes like Inc./Corp. ignored) to USAspending recipients and LDA clients — a conservative match that misses subsidiaries on purpose. See methodology and corrections.
