Klaviyo, Inc.: what insiders have been doing
Headquartered in Boston, United States, Klaviyo, Inc. belongs to the Technology sector and traces its origins to 2012. Filings by its managers are published through SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 96 filings came from 21 insiders.
Open-market activity splits into 1 purchase totalling €253k and 29 sales totalling €96.9M; 1 insider sit on the buying side and 6 insiders on the selling side. On balance, insiders were net sellers of €96.7M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The buyers include 1 senior executive. At €76.7M, the sale published on 13 August 2026 by Summit Partners L P is the largest of the period (1.9% of market cap).
The last insider purchase was made public on 17 February 2026, 243 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
Across the 5,814 companies tracked on its exchange, the median is 19 filings; at 96 filings, this issuer sits above that mark. Looking back to 2023, when coverage begins, insiders filed 4 purchases and 49 sales. In its latest annual report filed with the SEC (10-K, fiscal year ended 31 December 2025), the company reported revenue of 1.23 bn USD and net income of -31.8 m USD.

From a competitive standpoint, Klaviyo operates in a crowded marketing software market, but it has carved out a differentiated position through its B2C specialization, strong product depth for commerce-centric use cases, and close integration with major commerce ecosystems such as Shopify. That positioning is particularly relevant for brands seeking stronger retention, higher marketing efficiency, and more automation. The company serves an international customer base and has expanded beyond the Americas, with growing activity in Europe and Asia-Pacific supported by regional hubs in Dublin and Singapore.
Recent developments have been notable. In February 2026, Klaviyo reported full-year 2025 results showing 32% revenue growth and improved profitability, and it raised its fiscal 2026 outlook. In March 2026, the company announced a share repurchase authorization of up to $500 million, including a planned $100 million accelerated share repurchase, underscoring management confidence in cash generation and the durability of the business model. Klaviyo also highlighted new AI integrations and strategic partnerships with Google and Shopify, reinforcing its push toward more autonomous customer experiences and deeper commerce connectivity.
