Screenhero

Screenhero was a Y Combinator (W13) startup that built interactive screen sharing with voice and video, letting remote users share and control any application together. It was acquired by Slack in January 2015; the six-person team joined Slack and the standalone Screenhero product was discontinued, with its screen-sharing, voice, and video capabilities folded into Slack (today surfaced as Slack Huddles). The screenhero.com domain now 301-redirects to slack.com/features/huddles. No independent Screenhero developer portal, API, or SDK exists; this record is retained as a historical a16z portfolio-company lead in the API Evangelist network.

Screenhero is profiled on the APIs.io network. Tagged areas include Company, Screen Sharing, Video Conferencing, Collaboration, and Remote Work.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/screenhero: open an issue to ask a question, or submit a pull request to add artifacts.
