Braze

Braze is a customer engagement platform built around a real-time customer data model that ingests behavioral, transactional, and profile data via SDKs and REST APIs, then triggers personalized messaging across push, email, SMS, WhatsApp, in-app, Content Cards, and web. Its architecture centers on 'Canvas' (a visual, multi-step workflow builder with branching logic and A/B testing) and 'Campaigns' (single or multi-channel blasts), both driven by a low-latency event-streaming pipeline that can action data within seconds of ingestion rather than relying solely on batch ELT jobs. Currents, Braze's data export pipeline, streams engagement and behavioral event data to warehouses (Snowflake, BigQuery, Redshift) and pub/sub systems (Kafka, SQS, PubSub) for downstream analytics and reverse-ETL use cases. Engineering teams integrate Braze through native mobile SDKs (iOS Swift/Objective-C, Android Kotlin/Java, React Native, Flutter, Cordova, Unity), a JavaScript Web SDK, and a comprehensive REST API for server-side user tracking, catalog management, and message triggering. Liquid templating powers dynamic content personalization, while Connected Content allows synchronous calls to third-party APIs at send-time to enrich messages with live data. The platform exposes webhooks, a Cloud Data Ingestion pipeline for warehouse-native data sync, and partnerships with CDPs (Segment, mParticle, RudderStack) for teams that prefer decoupled data collection from the engagement layer. Braze primarily targets mobile-first consumer brands, retail/e-commerce, media/entertainment, and fintech companies with large, high-velocity user bases where marketing, growth, and product engineering teams need shared infrastructure for lifecycle messaging, push notification delivery at scale, and experimentation without building custom event-driven messaging infrastructure in-house.
