Graft Concepts

Graft Concepts was a consumer-electronics accessories company best known for the "Leverage" modular iPhone case, a latched aluminum-and-polycarbonate bumper frame with interchangeable backplates that let owners swap in kickstands, bike mounts, and 3D-printed backs. The company was a Y Combinator startup based in the San Francisco Bay Area and was acquired by Inseego (formerly Novatel Wireless) in January 2014, after which the independent product and brand were wound down. This profile was surfaced by the venture-portfolio scraper and added to the API Evangelist network as a stub; enrichment found no live developer surface, API, SDK, or documentation for the company. The original graftconcepts.com domain no longer serves the company and now resolves to a parked content page, so there are no API artifacts to catalog.

Graft Concepts is profiled on the APIs.io network. Tagged areas include Company, Consumer Electronics, Mobile Accessories, Hardware, and iPhone Cases.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/graft-concepts: open an issue to ask a question, or submit a pull request to add artifacts.
