Telesign

What Telesign does

Telesign Corporation, founded in 2005 and headquartered in Marina Del Rey, California, operates a Communications Platform as a Service (CPaaS) platform built around its proprietary Trust Engine, which combines machine-learning risk scoring (Intelligence), phone-number identity data (Phone ID), and unified multifactor authentication across seven channels (SMS, Silent Verification, Push, Email, WhatsApp, Viber, RCS). The company's underlying infrastructure consists of 700+ direct-to-carrier routes, 120+ points of presence, and a fraud consortium drawing on 5+ billion unique phone numbers, 2,200+ digital identity signals, and 35+ granted patents; 5+ billion unique phone numbers transit the platform monthly across the 230+ countries and territories it serves. Telesign monetizes primarily through usage-based, per-message and per-query API pricing for messaging and identity verification, supplemented by volume-based subscription pricing for enterprise customers with custom routing and committed-use contracts.

Telesign pursues an API-first go-to-market strategy with a developer self-serve portal (free trial, no credit card) backed by enterprise field sales, distributing under the Proximus Global brand family alongside BICS and Route Mobile. Primary go-to-market verticals are Financial Services and Fintech (banks, fintechs, payment platforms), with secondary coverage of Enterprise SaaS, e-Commerce, Travel & Hospitality, Gaming/Entertainment, and On-Demand Services; named customers include Salesforce, ByteDance, Citrix, EA, Ubisoft, HSBC, Affirm, OfferUp, Skype, Mamba, HERO, AstroPay, Amount, and Giftnix. The company is a wholly-owned subsidiary of Belgium's Proximus Global (publicly traded on Euronext Brussels under PROX) and was recognized as a Leader in the 2026 Gartner Magic Quadrant for CPaaS, following its 2025 consolidation under the Proximus Global brand.

Telesign carries material commercial and regulatory risks: it received a 2026 compliance direction from Australia's ACMA for transmitting 1,121 HSBC-impersonating scam text messages between 2020 and 2024 without timely reporting, the platform is unavailable in mainland China, and revenue / ARR figures are not publicly disclosed given its subsidiary status within Proximus Group.
