In plain words
Multiwoven is an open-source reverse ETL tool that syncs data from warehouses like Snowflake, BigQuery, Redshift, Postgres, and Databricks to business applications. It is designed for data developers and analysts who need to easily prepare and share data with marketing, sales, and other teams without building custom integrations. The tool aims to reduce friction between data teams and business stakeholders by automating data pipeline creation and maintenance.

In the maker’s words, at launch
Founder here. I want to show you Multiwoven - open-source Reverse ETL. I’ve spent close to two decades in jobs where data devs and business teams have been at loggerheads. Business balks at the long lead time for data requests or custom integrations. And data devs (or analysts/ops) hate the tediousness of these tasks. With the amount of data being captured and modeled only growing - Multiwoven’s been built for anyone to use the rapidly growing amounts of data in warehouses like Snowflake, BigQuery, Redshift, Postgres and Databricks - for easy preparation and sync to marketing, sales and other business tools. It’s been built using Ruby on Rails, ReactJS, TypeScript and Temporal. Data devs are under a lot of pressure to show business impact from data, especially in this economy. Developers have to tediously build (and maintain!) custom integrations & data pipelines themselves or have to consider purchasing expensive CDPs built for marketers, or third-party rETL SaaS tools. I also believe that people shouldn’t have to pay to move their own data to their own tools, and that it’s risky to hand over access of sensitive customer data to third-party SaaS tools. We’re open-source (data movement infra is free) and self-hosted (so data is in your control and never leaves the premises). Would love to get your feedback, as an early stage project.
