Vertical Semiconductor

Vertical Semiconductor is an MIT spinout developing next-generation vertical Gallium Nitride (GaN) power devices for AI data centers and grid infrastructure. Built on a decade of research from MIT's Palacios Group, its vertical GaN transistors push energy conversion closer to the chip with less power loss and heat, targeting high-voltage applications from 100V to over 2kV. The company claims up to 30% higher efficiency, a 50% smaller power footprint, and 10% lower total cost of ownership versus silicon, and has demonstrated its platform on 8-inch wafers using standard silicon CMOS manufacturing. It is a hardware/deep-tech power-electronics company with no public API, developer portal, SDK, or OpenAPI surface. Backed by Playground Global.

Vertical Semiconductor is profiled on the APIs.io network. Tagged areas include Company, Compute, Semiconductors, Power Electronics, and Gallium Nitride.

Vertical Semiconductor’s developer surface includes engineering blog and 3 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/vertical-semiconductor: open an issue to ask a question, or submit a pull request to add artifacts.
