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.
