Twilio & Segment Agency

What is Twilio?

Twilio is a cloud communications platform (CPaaS) that lets you add messaging, voice, email and more to your applications through APIs. Its products span Programmable Messaging (SMS, MMS and WhatsApp), Programmable Voice, Verify (2FA/OTP), email via Twilio SendGrid, Twilio Flex for contact centres, and Twilio Segment — a leading customer data platform (CDP).

Increasingly, Twilio is where teams build AI-powered communications — conversational messaging and real-time AI voice agents connected to large language models — grounded in unified customer data from Segment.

Twilio Segment (CDP)

Ethisys is a Twilio Segment gold partner. Segment is a customer data platform (CDP) that collects, cleans and unifies customer data from every source into a single view, then activates it across your marketing, analytics and communication tools.

We design and deliver Segment end to end — tracking plans and data governance, source and destination integration, identity resolution and unified profiles, Protocols and data quality, Connections, Personas/Engage audiences, and Reverse ETL. We've delivered Segment at enterprise scale, including for Sage.

Paired with Twilio's messaging and voice, Segment lets you act on customer data in real time — triggering the right message, on the right channel, at the right moment.

Twilio + AI

We're an AI agency as well as a Twilio agency, so this is our sweet spot. We build AI voice agents and conversational bots on Twilio — grounded in your data (including Segment profiles) with retrieval-augmented generation, human hand-off and the guardrails production needs.

That means real-time voice assistants, automated customer conversations over WhatsApp and SMS, and LLM-assisted support that connects to your systems.

How Ethisys helps

From a single messaging integration to a full contact-centre, Segment CDP or AI voice build, we deliver on Twilio end to end — implementation, custom applications, integration, migration and support — with senior specialists, enterprise-grade quality and better value than large agencies.
