The internet deserves
better information
We are building the infrastructure to make quality information findable, verifiable, and accessible to everyone, at a fraction of the cost it takes today.
"To help improve the legitimacy of content on the web, and help people, companies, and organizations around the world get to better, higher quality information quicker and with less cost."
With AI accelerating the production of content at an unprecedented scale, the ability to distinguish signal from noise has never been more critical. We believe this is one of the most important problems to solve in the next decade, and we are committed to solving it.
Legitimacy
We measure who actually has authority on a given topic, based on real public signals rather than opaque editorial judgment or follower counts.
Speed
Our index updates continuously. Researchers, journalists, and companies get access to current authority signals without manual research or waiting weeks for reports.
Accessibility
Information quality should not be a luxury. We are building a service that scales from independent researchers to global enterprises without prohibitive cost.
AI makes this more urgent, not less
The explosion of AI-generated content means the volume of information on the web is growing faster than any human or traditional system can evaluate. At the same time, the cost of producing convincing but inaccurate content has dropped to near zero.
An authority layer on top of the web is not a nice-to-have. It is becoming foundational infrastructure for anyone who needs to act on information: fact-checkers, procurement teams, journalists, researchers, AI systems themselves.
We started building this before it was fashionable. We intend to be the definitive answer to the question: who actually knows what they are talking about?
The people behind
the Authority Index
We're a tight-knit team with deep roots in public and social media data. Many of us have been working together for 5 to 10+ years. We know each other's strengths, we move fast, and we've built in this space long before it was fashionable.
