System1, Inc.: what insiders have been doing
System1, Inc. is a Media & Communication company. Its directors and officers file their transactions with SEC (Form 4). In the past year (22 October 2025 to 22 October 2026), 21 filings came from 4 insiders.
The flow runs one way only: 1 insider bought (1 purchase totalling €68k) and nobody sold on the market. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Biggest ticket of the year: €68k, bought by Kidambi Tridivesh and made public on 17 April 2026 (0.31% of market cap). Among those who bought: 1 finance chief.
Across the 2,023 companies tracked on its exchange, the median is 41 filings; at 21 filings, this issuer sits below that mark. The full history, which starts in 2022, counts 53 purchases against 29 sales. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 266.1 m USD and net income at -65.3 m USD.
The most recent open-market purchase was published on 17 April 2026, 190 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4.
Elsewhere in the same sector, our signals recently picked up insider purchases at ZEAL Network SE and CTS Eventim AG & Co. KGaA. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.

About System1, Inc.
System1, Inc. (NYSE: SST) is a United States-listed company traded on the NYSE that operates in digital media, online advertising, and customer acquisition. Headquartered in Marina del Rey, California, the company was founded in 2013 by Michael Blend and Chuck Ursini with a strategy built around combining data, technology, and advertising optimization to better monetize consumer intent. Over time, System1 has evolved into a two-part platform: first, an AI-powered marketing and traffic-acquisition engine; and second, a portfolio of consumer internet brands and utilities. Its flagship assets include CouponFollow, MapQuest, and Startpage.com, alongside other shopping, travel, and search-oriented properties. This makes System1 a hybrid business positioned at the intersection of performance marketing, digital media, and internet services, serving advertisers, publishers, and brands through an omnichannel customer-acquisition model. In competitive terms, the company operates in a fragmented but intensely competitive landscape dominated by large search, ad-tech, and digital media players. Its differentiation lies in its focus on user-intent signals, proprietary monetization tools, and an increasing emphasis on artificial intelligence. A notable strategic development was the August 2024 corporate reorganization, which created clearer separation between the Products and Marketing businesses and improved the operating structure of the group. Recent highlights include a 1-for-10 reverse stock split that took effect on June 12, 2025, with SST continuing to trade on the NYSE on a split-adjusted basis. More recently, first-quarter 2026 results highlighted a solid gross margin profile and management’s stated focus on the intersection of AI and consumer intent. For investors, System1 remains a U.S. small-cap story with a mixed profile: exposed to the cyclical nature of digital advertising, but supported by a recognizable asset base, a differentiated technology stack, and a strategy increasingly tied to AI-enabled internet usage.
