EchoIndex: The Secondary Knowledge Market

Turn your private research and niche reading lists into passive equity by licensing your information curation.

EchoIndex is a marketplace where experts and obsessive researchers sell access to their living knowledge bases. Unlike newsletters that disappear in the inbox, EchoIndex allows users to subscribe to a live-synced, categorized, and annotated research feed from vetted curators in high-stakes industries like biotech, green-tech, and deep-tech.
