OneModel - "atomic knowledge", or a new way to manage knowledge by looking at it differently. The vision subsumes essentially all KM & notetaking etc products, and the current iteration is a text-mode bare AGPL3 app that I use every day (no mobile support yet, other features still in the pipeline...).

Hopefully explained at the site "About" link and its links (if not let me know!): http://onemodel.org

(ps: I'd love to talk about funding etc.)
