  TeleSign is a global leader in digital identity verification, fraud prevention, and programmable communications, headquartered in Marina del Rey, California. Founded in 2005 by Darren Berkovitz, Ryan Disraeli, and Stacy Stubblefield, TeleSign pioneered the use of phone-based two-factor authentication (2FA) to secure online accounts. Today, the company provides a suite of APIs and data intelligence services that help enterprises verify users, detect fraudulent activity, and engage customers through reliable messaging and voice channels. TeleSign’s core technology leverages machine learning and analysis of over five billion unique phone numbers monthly—covering approximately half of the world’s mobile users—to deliver real-time risk scoring, phone number intelligence, and seamless authentication. The company serves many of the world’s largest digital brands, including 20 of the top 25 global internet companies. In 2017, TeleSign was acquired by BICS, a subsidiary of the Belgian telecom group Proximus, for $230 million. Following the acquisition, TeleSign became a key component of Proximus Group’s international growth strategy, later expanding through the acquisition of Route Mobile. TeleSign positions itself within the Communications Platform as a Service (CPaaS) market, competing with Twilio and others, while differentiating through its deep focus on identity security and trust. In 2023, Christophe Van de Weyer was appointed CEO to lead the company through its next stage of growth.
