Qadium creates and organizes knowledge about the world's devices.

We continually index all devices connected to the public Internet. Our global platform enables organizations to:
· Understand their networks and how they relate to the broader world
· Discover relevant changes across the global Internet
· Make informed decisions with quantified network measurements

Expander provides global Internet sensing results relevant to your organization. Investigate how your networks change, and receive near real-time alerts, all in a common web browser.

No hardware install. No software install. No behind-the-firewall access required.

Help Us Build Something New

At Qadium, you'll work with best-in-class software engineers and algorithms experts from Stanford, Caltech, and MIT to build out the first global Internet sensing platform. In the course of your day, you might deploy your code to a globally-distributed platform, structure data in our massive database, or develop new insights and algorithms for exploring data that has never been collected before. If you get your kicks from novelty, autonomy, and semi-supervised massively parallel systems, we want to hear from you.

Our Customers

Qadium provides global Internet sensing for industry leaders in financial services, auditing & consulting, retail, healthcare, defense, and insurance.

We also work with several US Government agencies. All of our work is defensive for critical infrastructure protection, and helping US service members avoid operational security risks.

Qadium does not, has not, and will not support offensive cyber operations or provide bulk Internet sensing data to any government.

About Us


Qadium was founded in 2012. We were seeded by the Pentagon’s blue-sky research arm, the Defense Advanced Research Projects Agency (DARPA), to prototype next-generation data and network analysis technologies. In its early R&D work, Qadium invented aspects of its relationship-based search engine, global sensing platform, and associated analytic modules.

The co-founders of Qadium met while working together as technical consultants on a special project at DARPA’s headquarters. We have since grown from a small group of algorithms experts into an enterprise software company focused on Internet sensing products. Qadium is now backed by top Silicon Valley venture capitalists, including Peter Thiel (Founders Fund) and Scott Sandell (NEA), and a rapidly growing network of commercial customers and partners.

Mission & Vision

We create and organize knowledge about the world’s devices. Major Internet search companies focus on scraping web content, facilitating keyword search across that content, and monetizing ad revenue. Those tools only solve part of the problem of understanding the global Internet and making better decisions related to information technology. Machine-to-machine communication – what Qadium calls the “device layer” of the Internet – comprises a similar proportion of Internet traffic as the web. However, until now, this part of the Internet has only been monetized by selling products and connecting them to each other.

Qadium is the first company to build a technology and product to solve the problems of generating data and knowledge about the device layer of the Internet. Previous approaches to try to understand relationships between devices have been expensive, labor-intensive, and incomplete. With our platform, large enterprises and government agencies can understand relationships between devices at Internet scale, both within their networks and outside of their known IP space. Qadium is pursuing the addressable market of all IT transactions involving asset management or network security.
