StanzaCal, also known as Stanza, was a calendar synchronization and event discovery platform. It enabled users to subscribe to various public calendars (e.g., sports, TV shows, academic schedules) and integrate them seamlessly into their personal digital calendars like Google Calendar, Outlook, and Apple Calendar. Stanza also offered tools for publishers and brands to distribute their event information through 'add-to-calendar' buttons and calendar marketing solutions. The company was acquired by IRL (In Real Life) in 2021. IRL subsequently shut down in June 2023.
The San Francisco headquarters served as the central hub for product development, engineering, marketing, sales, and overall business operations for Stanza's calendar platform.
Likely a typical modern tech office designed to foster collaboration and innovation, common in the San Francisco startup scene. Specific architectural details are not widely publicized.
As a venture-backed startup, Stanza's work culture was likely fast-paced, innovative, and product-focused, with a strong emphasis on engineering and user growth. It would have embodied the entrepreneurial spirit of Silicon Valley.
The San Francisco HQ was crucial for Stanza's growth, allowing it to tap into the rich talent pool, venture capital network, and tech ecosystem of the Bay Area, facilitating its development and eventual acquisition.
While Stanza's physical offices were primarily in the United States, its digital platform and services were accessible to users worldwide. The 'add-to-calendar' functionality and event subscriptions were used by a global audience, and partnerships often included international sports leagues and organizations. Post-acquisition by IRL and IRL's subsequent shutdown, Stanza's operational presence ceased.
Information on the specific street address is not consistently public, common for startups that may have moved or used co-working spaces. Historically, they were in the SoMa or FiDi district.
