Sessions

Sessions (Session Technologies, formerly Flow OS) was a Bucharest-based unified communication and collaboration platform founded in 2021 by Radu Negulescu and Radu Tintescu, backed by earlybird's Digital East Fund (invested 2022, lead Dan Lupu). The product bundled voice, video, chat, webinars and meetings with third-party productivity integrations on a proprietary "Flow OS" framework at sessions.us. As of this enrichment pass (2026-07-21) the company appears defunct: the sessions.us domain no longer serves the product (it resolves to an unrelated parked/casino-spam page behind a bare-IP TLS certificate), the docs, developers and api subdomains do not respond, and no live developer, API, OpenAPI, SDK or documentation surface could be located to enrich. This profile is retained as a portfolio lead record; no API artifacts exist to harvest.

Sessions is profiled on the APIs.io network. Tagged areas include Company, Communications, Collaboration, Video Conferencing, and Webinars.

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