A portfolio of projects is a list. A portfolio of categories is a structure. This essay sets out why Arc organises its work as eight categories, and how the visible projects are evidence of that deeper structure rather than the structure itself.

Categories as commitments

Each category is a standing commitment to a region of the frontier — a place Arc expects to hold deep technical options, whether or not a product exists there yet.
