Twilio
Twilio provides APIs for embedding SMS, voice, WhatsApp, video and email into applications, combined with first-party data and AI for customer engagement, fraud prevention and contact centers.
Twilio, founded in 2008, is a cloud communications and customer engagement platform. Its core product is a set of APIs that let developers embed SMS, voice, WhatsApp, video and email directly into their applications, abstracting the complexity of the global telecommunications network. The Communications APIs are used by more than 335,000 businesses and by millions of developers daily.
Beyond communications, Twilio offers a Customer Engagement Platform that combines those APIs with first-party data and artificial intelligence. The platform is applied to fraud prevention and user verification, marketing campaigns and contact centre technology, alongside the CPaaS layer. In 2025 Gartner named Twilio a Leader in its Magic Quadrant for CPaaS, positioning it highest for Ability to Execute.
Technical work spans cloud communications, APIs, artificial intelligence, first-party data, identity verification, contact centre technology and marketing automation, across industry verticals including telecommunications, marketing, security and developer tools. The company has a global footprint. Its stated mission is to democratise access to communication tools once available only to telecom giants, with an emphasis on developer-centric design and on personalisation and durable customer relationships.
