VonBox

VonBox operated as Vonjour (vonjour.com), a Santa Monica, CA cloud communications startup offering phone, text messaging, and contact center services for small businesses, backed by 500 Global (then 500 Startups) and Kima Ventures circa 2014-2015, including a Vonjour for 500 Startups perk program. The vonjour.com website is no longer live (DNS resolves but HTTP does not respond), and no public API, developer documentation, or client packages are published. The founding team (Daniel Tawfik, Aman Fahimullah) went on to build ZenPatient (zenpatient.com), a digital health platform, and the company GitHub organization github.com/Vonjour is now branded ZenPatient.

VonBox is profiled on the APIs.io network. Tagged areas include Company, Communications, Telephony, Messaging, and Contact Centers.
