What Turn It On does

Telesign, the subject of the underlying data (the Turn It On firmographic header describes a separate free 2FA awareness resource at turnon2fa.com), provides cloud-based communications and digital identity APIs focused on phone-based verification and multifactor authentication. The core product, Verify API, unifies seven verification channels (SMS, Silent Verification, Push, Email, WhatsApp, Viber, and RCS) behind a single API integration, with features such as multichannel fallback (a waterfall approach to failover across channels), custom routing to optimize cost and reliability by market, verified sender IDs, and frictionless authentication that removes one-time passcodes. The platform sits within a broader Trust Engine that bundles Identity (real-time phone-based digital and behavioral signals via Phone ID), Intelligence (ML-driven risk scoring across the largest mobile identity datasets globally), and Verify API under a unified trust architecture. Telesign pioneered SMS verification and holds patents on time-based OTP phone-based verification methods, with 15+ years of data science expertise layered on top of exclusive mobile network operator (MNO) partnerships that provide direct-to-carrier routing.

The company sells primarily to enterprises and developers across eight verticals: Financial Services, Enterprise Software, e-Commerce and Retail, Travel and Hospitality, Entertainment (gaming), and On-Demand Applications. Named enterprise customers include Ubisoft (gaming), Mamba (dating/social, with a documented 50% verification cost reduction), Amount and AstroPay (payments/fintech), and OfferUp (marketplace). Revenue is generated via usage-based API billing under a freemium trial model with a self-service developer portal and an enterprise 'Talk to Sales' motion for larger contracts. Distribution relies on an API-first, developer-centric go-to-market: SDKs, API reference, tutorials, sample code on GitHub, plus content marketing, developer relations, events, webinars, and a Continuous Trust Authority badge program that turns each verified customer into a co-branded trust signal.

Telesign operates globally with customizable routing across markets and channels, with an explicit restriction that its Omnichannel Experiences product is not available in the Chinese mainland. The company is privately held and operates as a subsidiary within the Proximus group (the Belgian telecommunications conglomerate), alongside Route Mobile and BICS in the 'Proximus global' brand family. Operating status is active, with continuous product launches, multiple industry landing pages, and a diversified enterprise customer base.
