Companies that use Sentinel Pro

Source: Analysis of tech stacks from 23 companies that use Sentinel Pro

I noticed that Sentinel Pro users are digital media companies and publishers focused on advertising monetization. The technology stack reveals a heavy concentration of ad tech platforms, specifically programmatic advertising tools like LiveRamp, Lotame, PubMatic, and Criteo. These aren't companies experimenting with ads as a side revenue stream. They're organizations where digital advertising is core to their business model.

The pairing of LiveRamp and Lotame is particularly telling. LiveRamp handles identity resolution across platforms, while Lotame manages audience data and segmentation. Together, they suggest these companies are building sophisticated first-party data strategies to maximize ad revenue in a privacy-conscious world. The presence of PubMatic, a supply-side platform, confirms they're selling ad inventory programmatically at scale. Parse.ly appearing in the mix makes sense too, as content publishers need analytics to understand which articles drive engagement and can command premium ad rates.

My analysis shows these are marketing-led organizations operating in the growth to maturity stage. They've moved past basic display advertising into complex programmatic operations that require multiple specialized platforms working together. The DigiCert DNS presence across 20 companies suggests they're handling significant web traffic and need enterprise-grade security. This isn't a product-led motion where users discover value independently. These companies require active relationship management given the technical complexity of integrating multiple ad tech vendors.

I noticed that Sentinel Pro's customers are predominantly digital media and publishing companies that produce online content at scale. These aren't traditional publishers. They're creating thousands of articles, guides, reviews, and videos across entertainment verticals like gaming, movies, tech, automotive, and sports. They build audience engagement through expertise-driven content and monetize through advertising and affiliate relationships.

These are mature, established operations despite their modest headcounts. Most have 11-200 employees and have been operating for 5-20 years. The striking pattern is that 19 of the 23 companies are owned by Valnet Inc., suggesting this is really a portfolio company using Sentinel Pro across its properties. The few independent companies like Military.com (Series C, $5.5M funding) and Polygon (secondary market stage) are also well past the startup phase. They're scaled content operations managing large contributor networks and producing high volumes of published material.
