Hightouch

Hightouch is the pioneer of the 'Warehouse-Native' architecture, specifically designed to replace traditional, siloed Customer Data Platforms (CDPs) with a composable layer. By 2026, Hightouch has solidified its position as the market leader in Reverse ETL, enabling enterprises to leverage Snowflake, BigQuery, and Databricks as their primary source of truth. Its technical core revolves around a high-performance orchestration engine that queries data warehouses and maps results to the APIs of over 200+ SaaS applications like Salesforce, Braze, and Facebook Ads. Unlike legacy systems, Hightouch does not store a separate copy of customer data, ensuring maximum security and compliance. Key architectural advancements include 'Identity Resolution' at the warehouse layer, enabling teams to stitch user profiles using SQL, and a 'Personalization API' that allows low-latency retrieval of warehouse traits directly into web and mobile applications. This 'Zero-Copy' approach minimizes data latency and eliminates the 'garbage-in, garbage-out' problem prevalent in traditional data pipelines.
