About
Insider was founded in 2012 in Istanbul by Hande Cilingir and co-founders as a customer data and personalization platform built to give enterprise marketing teams the ability to personalize experiences across every digital touchpoint without engineering involvement. The platform was designed from the ground up to unify customer data from web, mobile, email, messaging apps, and offline sources into a single profile and activate it for real-time personalization. Founding in a high-growth emerging market shaped a platform architecture suited to complex, multi-channel consumer behavior at global scale.\n\nInsider's platform spans CDP, omnichannel personalization, AI-powered segmentation, and journey orchestration — enabling campaigns across web, app push, email, SMS, WhatsApp, and on-site experiences from a single interface. Sirius AI powers predictive audience segmentation, next-best-action recommendations, and generative content capabilities. Insider holds #1 G2 rankings across nine CDP and personalization categories and serves 1,000+ enterprise clients in retail, travel, financial services, and telecommunications.\n\nInsider closed a $500 million Series E in 2024 led by General Atlantic, bringing total funding to $772 million. The company reported $150 million in revenue for 2024 and operates globally across Europe, Asia-Pacific, the Middle East, and the Americas. As third-party cookie deprecation accelerates and brands invest in first-party data infrastructure, Insider's unified CDP-plus-activation platform is positioned to capture growing enterprise marketing technology spend.

About
Segment (now Twilio Segment) is Twilio's customer data platform (CDP) that collects, unifies, and routes customer behavioral data from websites, mobile apps, and server-side sources to analytics tools, marketing platforms, and data warehouses. Originally founded independently in 2011 by Peter Reinhardt, Calvin French-Owen, Ilya Volodarsky, and Ian Storm Taylor, Segment was acquired by Twilio in 2020 for $3.2 billion — the largest acquisition in Twilio's history — and integrated as the foundational data layer for Twilio's customer engagement platform.\n\nSegment's core product is a universal data collection API (analytics.js for web, mobile SDKs) that captures user events and identity data once, then routes it to 400+ downstream destinations — Mixpanel, Amplitude, Salesforce, Braze, Snowflake, BigQuery — without requiring separate tracking implementations for each tool. The Personas feature builds unified customer profiles from event streams, enabling personalization and audience segmentation across channels.\n\nIn 2025, Twilio Segment operates as the data infrastructure layer for Twilio's broader customer engagement suite, connecting event data collection with Twilio's messaging, voice, and email channels. The CDP market has grown competitive with Rudderstack (open-source alternative), mParticle, and cloud warehouses offering native CDP functionality. Segment's 2025 strategy focuses on deeper Twilio product integration, AI-powered audience building, and expanding its Protocols data governance capabilities for enterprise compliance.
