Knowable

Knowable was a mobile audio-learning company that united world-class experts, thinkers, and storytellers to produce structured audio courses for curious minds — an "audio courses" take on online learning delivered as serialized lessons rather than one-off podcasts. Founded by the Bit Kitchen team and backed by Andreessen Horowitz (a16z led its round in May 2019), Knowable published expert-led course series across business, creativity, and personal development. The company is no longer operational: knowable.fyi now serves a tombstone notice stating that Knowable has been acquired by Medium and directing former listeners to Medium.com. Knowable never published a public developer program, API, SDKs, or developer documentation, and its GitHub organization (bitkitchen) exposes no public repositories. This profile is retained in the API Evangelist network as a historical company record from the a16z portfolio; there is no live API surface to catalog.

Knowable is profiled on the APIs.io network. Tagged areas include Company, Audio, Learning, Education, and Media.

Regulatory Posture applies to this provider. Its tags matched the Education & Research 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/. This rating is computed from github.com/api-evangelist/knowable: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
