Daniel Miessler

Hi,

My name is Daniel Miessler and I'm an AI / Security Researcher and Founder based out of the San Francisco Bay Area.

My goal is to help bring about the good version of an AI future—which I call Human 3.0—and avoid the bad one. In order to do that, I build AI systems, companies, products, and tools that upgrade people and organizations rather than try to replace them. E.g.:

  • threshold.app — An AI-powered content filtering system that rates the quality of content and lets you decide how good it has to be before it's shown to you. Addresses the problem too much content and too little time, as well as the problem of individual writers/creators being ignored because they don't have a large audience.
  • HELIOS — An AI-augmented state monitoring system.
  • SAMEPAGE — An AI-augmented system for maintaining startup focus so they can sell and go to market effectively.
  • KNOSIS — An AI-augmented daily intelligence brief product.
  • (more to come)

I also advise and consult with companies on how best to become antifragile against the AI environment that's coming.

To look around, you can check out my blog, telos, projects, ideas, and/or predictions—or a deeper version of this explainer on the about page.

Known Projects ​

  • The Fabric AI Framework, released in January of 2024, which is a set of crowd-sourced AI solutions that address specific work and personal use cases. Over 30K stars in less than 30 months.
  • The SecLists project, which serves as a Pentester's essential List of Lists, and it's been part of Kali Linux since 2018.
