Twilio Segment is a customer data platform (CDP) that collects, unifies, and activates customer data across an organization's entire technology stack, with AI-powered features for identity resolution, audience building, and predictive analytics. Originally founded as Segment in 2011 by Peter Reinhardt, Ilya Volodarsky, Calvin French-Owen, and Ian Storm Taylor, the company was acquired by Twilio in 2020 for $3.2 billion. Segment is headquartered in San Francisco, California. The platform serves as a central data infrastructure layer that collects first-party customer data from websites, mobile apps, servers, and cloud applications through a single API and standardized event tracking specification. It then cleans, deduplicates, and unifies this data into comprehensive customer profiles using identity resolution algorithms that stitch together anonymous and known user identities across devices and channels. Segment distributes this unified customer data to downstream tools and destinations including analytics platforms, data warehouses, marketing tools, advertising platforms, CRM systems, and personalization engines through over 400 pre-built integrations. This eliminates the need for point-to-point integrations between tools and ensures all systems work with consistent, high-quality customer data. Segment Protocols provides data governance through a tracking plan that validates data quality before it reaches downstream destinations. Segment Unify builds unified customer profiles with computed traits and audiences that update in real time. The platform includes AI features such as predictive traits that use machine learning to predict customer behaviors like likelihood to purchase or churn, and generative AI capabilities through CustomerAI that enable natural language audience building. Segment offers multiple pricing tiers: a free plan for startups with limited event volumes, a Team plan with core CDP functionality, and a Business plan with advanced features including identity resolution, data governance, and premium support.
