Arcturus

Arcturus (Arcturus Technologies) is a Los Angeles advanced-materials company founded by Amir Mashal that infuses carbon nanomaterials into metals to create a new class of conductors, using lasers to embed carbon into copper and dramatically improve its electrical, thermal, and mechanical performance. Positioned in frontier climate/energy tech, its drop-in materials target motor windings, bus bars, heat sinks, data-center infrastructure, electric motors, drones, robotics, and — over time — transmission lines and grid infrastructure. The company emerged from stealth in June 2026 with an $8M seed round led by Initialized Capital, with 1517, Breakthrough Energy Discovery, Toyota Ventures, and Wireframe Ventures participating. This is a deep-tech hardware/materials company with no public API or developer program; the profile is maintained as an API Evangelist network company record.

Arcturus is profiled on the APIs.io network. Tagged areas include Company, Frontier Tech, Advanced Materials, Carbon Nanomaterials, and Energy.

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