Kumu Networks

Kumu Networks, Inc. is a Sunnyvale, California semiconductor and RF technology company founded in 2011 to commercialize Stanford University research into full-duplex wireless and self-interference cancellation (SIC). Its silicon and module products — RF integrated circuits, cancellers such as the K8 canceller prototype, and self-interference-cancelling smart repeaters — let a radio transmit and receive on the same or an adjacent channel at the same time, across roughly 200 MHz to 60 GHz, targeting 4G/5G/6G infrastructure, Wi-Fi, IoT, satellite, and defense and aerospace programs including US Army demonstrations and Department of Defense dynamic spectrum-sharing work. The company raised roughly $45M from investors including Khosla Ventures, New Enterprise Associates, Cisco Investments, Deutsche Telekom, Verizon Ventures, Swisscom, Singtel Innov8 and Third Point, and its shares trade on secondary marketplaces. Kumu Networks licenses hardware IP and sells modules to wireless equipment manufacturers rather than operating a public developer platform: as of August 2026 it publishes no developer portal, API documentation, OpenAPI/AsyncAPI specification, SDKs, CLI or public code repositories, and its own website at kumunetworks.com returns HTTP 404 from its WP Engine host (last successful Internet Archive capture 2024-08-10).

Kumu Networks is profiled on the APIs.io network. Tagged areas include Company, Semiconductors, Wireless, RF, and Spectrum.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications 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.

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/.
