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.

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.
