It does not move data. * Event collection (Segment, RudderStack) captures behaviour from your own apps. * Reverse ETL (Hightouch) pushes warehouse models back out to sales and marketing tools. * Compare billing metrics carefully — active rows, GB, events and connectors produce wildly different bills for the same pipeline. ## Frequently Asked Questions What are the best data & etl tools for startups in 2026?⌄ The best data & etl tools for startups in 2026 include dbt, Fivetran, Hightouch, Airbyte, Estuary Flow.
