Overview
Matillion is a cloud-native data integration and transformation platform built for modern cloud data warehouses such as Snowflake, Redshift, Databricks, and BigQuery. It provides visual, low-code pipeline development with strong orchestration and transformation capabilities, making it suitable for enterprise-scale workloads. While powerful, it is often considered more complex and better suited for mature data teams.
Large library of connectors
Strong orchestration and transformation features
Suitable for large enterprises with complex data workloads
Supports both ETL and ELT patterns
Flexible, visual pipeline development
Can be expensive for smaller teams
Steep learning curve for non-technical users
Overkill for simpler or smaller data operations
A reviewer on G2 said::
“Built-in connectors to many systems, ability to create custom connectors, and an active community with quick responses to technical questions.”
“Some components feel clunky, and certain cloud features lag behind older versions.”

Side-by-side
Weld offers a simple and predictable pricing model starting at $79 for 5 million active rows. This flat, usage-transparent structure makes budgeting straightforward for small and medium-sized teams.
Matillion uses a consumption-based pricing model that can become costly as workloads grow, making it less accessible for smaller teams or early-stage companies.
Pricing is on the higher side compared to alternatives, which may be challenging for smaller teams, especially as reporting needs scale.

Weld provides ELT ingestion, SQL-based transformations, reverse ETL activation, data lineage, orchestration, and workflow management in a single platform. Its AI assistant accelerates modeling and transformation tasks.
Matillion provides extensive transformation, orchestration, and data integration features with a large connector ecosystem. However, it focuses heavily on ETL/ELT and does not cover end-to-end data activation or reverse ETL.
Whatagraph focuses primarily on marketing reporting and automation. While it supports many common marketing connectors, it lacks advanced features such as data modeling, transformations, and cross-system syncing.

Side-by-side
Users can model data using SQL enhanced by Weld’s AI assistant, automate workflows, and build custom connectors to any API. This provides strong flexibility for teams that want to tailor integrations and transformations within one platform.
Matillion is highly flexible for complex enterprise pipelines, but the platform’s depth can introduce complexity, making it less suitable for teams seeking a simple or lightweight solution.
The platform is straightforward for simple reporting but offers limited flexibility for deeper customization or complex data workflows, making it less suitable for technical or data-driven teams.

CUSTOMER STORIES
“One of the biggest impacts has been unlocking new ways to buy media. Before, we didn’t have the data to back up strategic decisions – now we do.”
“Before Weld, we had to rely on custom Python scripts and manual processes that were time-consuming and error-prone.”
“We’re still a team of three, but we’re often doing far more than the equivalent of three full-time employees. That’s down to how we're able to leverage systems, data, and processes.”
“We’ve always been a KPI-driven company. But we wanted to scale that mindset across every team member, every team, every decision.”
“Before Weld, our data infrastructure was limited and we relied heavily on Excel files and custom Python scripts.”
“Weld has saved us a ton of time, from not having data ready to having a fully functional data warehouse and connectors.”
“By integrating Weld, Amazon S3, and Databricks, Soundboks built a modern data pipeline that automates data ingestion, improves reporting, and provides up-to-date visibility into sales performance”
“We didn’t have a good data setup, so we lacked the business insights we needed. Weld has allowed us to set up a structured data infrastructure and access insights quickly.”
