I applied again to YC as an NFP. Did that some years ago, perhaps now is ripe. The goal is to sort out governance of an open source approach to legal documents, and to transacting generally. In the intervening years since the first application, have benefitted from work with MIT Connection Science, EU Commission, Harvard Berkman-Klein, Stanford CodeX. And now also Metagov.org (presentation with Megan Ma). YC could be a fabulous place to work out what parts of an open transacting system need governance in a "Centre for Decentralised Law" (#DecentLaw). It could also be a user - as demonstrated with the example of the Safe Note, above.
A piece of this is to eliminate the friction of legal text by open sourcing legal templates, in a graph, on GitHub. The key word here is "source." Legal documents currently are blobs, not source. See github.com/CommonAccord/ Lots of exampless, including the YC SAFES, Series Seed, GA4GH data sharing, etc. It's not full algorithmic, but compatible with algorithmic approaches, like Mike Genesereth's and Meng's.
