Overview
Weld is a unified ELT and data activation platform that combines ingestion, modeling, transformations, orchestration, lineage, and reverse ETL in a single SaaS interface. With premium in-house–built connectors, an intuitive UI, and near real-time syncs, Weld enables both technical and non-technical users to create and manage data workflows efficiently. Weld also includes an AI assistant to support SQL modeling, generate transformations, and streamline repetitive tasks. Teams can ingest data from a wide range of sources—including marketing platforms, CRMs, databases, Google Sheets, Excel, and APIs—into their cloud data warehouse and activate it back into business tools.
Lineage, orchestration, and workflow features included by default
Handles large datasets and near real-time data sync
ELT and reverse ETL in one platform
User-friendly interface with minimal setup required
Flat, predictable monthly pricing model
200+ in-house–built, high-quality connectors
AI assistant for modeling and transformations
Some SQL knowledge is useful for advanced modeling
Optimized for cloud-warehouse workflows (Snowflake, BigQuery, Redshift, etc.)
Feature set is streamlined for modern ELT/activation use cases

Overview
Twilio Segment is a customer data platform (CDP) focused on collecting, unifying, and activating customer event data across products and channels. It centralizes behavioral data from web, mobile, and server sources, and uses identity resolution to build unified customer profiles. Segment is heavily oriented toward marketing, product, and analytics use cases, offering pre-built integrations and Reverse ETL capabilities to sync cleaned data back into operational tools. While powerful for customer data workflows, Segment is less suited for teams looking for a general-purpose ELT platform.
Strong real-time event tracking and data collection
Large catalog of fully managed marketing and product integrations
Identity resolution and audience management features
Reverse ETL powered by native integrations and dbt model sync
Becomes expensive quickly as usage scales
Not ideal as a standalone ELT platform
Optimized for marketing and product tools rather than general data engineering
Customization and complex integrations can require significant setup effort
A reviewer on G2 said::
“Segment connects to all the various platforms that we're using which makes it very easy to send data around. No engineering needed.”
“Pricing could be a bit more affordable, especially if you want to use ETL processes.”
Overview
Supermetrics is a powerful data integration tool that's particularly popular among marketers. It allows you to fetch data from various marketing platforms, such as Google Ads, Facebook Ads, and Google Analytics, and then transfer it into a data warehouse, spreadsheet, or BI tools like Looker, Google Data Studio, or PowerBI. The automation it provides saves time and reduces the chance of errors that come with manual data transfers.
Easy to use
Pre-built reports
Google Sheets destination
Flexibility in data storage and visualization options
Complex pricing model
Expensive
Limited data transformation capabilities
Slow data refresh rates
Can be glitchy
Not suitable for very large datasets
A reviewer on G2:
“Supermetrics is so easy to use, and the user interface for Google Sheets is intuitive and fast. There is a huge number of connectors available. I liked the scheduling options in my legacy plan, with hourly refreshes available. The customer support is premium and fast.”
“There is a limited set of connectors available in the less expensive pricing plans, and the pricing has increased significantly over the years.”
Side-by-side
Weld’s interface is built for clarity and speed, enabling users with varying levels of technical experience to manage data pipelines and models efficiently. Its built-in lineage and orchestration tools provide transparency across workflows.
Segment offers an accessible interface for collecting and routing customer data, but advanced setups—such as identity merging, custom sources, or Reverse ETL modeling—can require more technical configuration.
Supermetrics is easy to use, especially for marketers who need to fetch data quickly from various platforms and transfer it to spreadsheets or BI tools.

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.
Segment provides a free tier, but pricing scales rapidly with event volume and advanced features. Many businesses find it expensive once usage grows or enterprise features are enabled.
The pricing model for Supermetrics can be complex and expensive, which might be a concern for small businesses or those with limited budgets.

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.
Segment includes real-time event tracking, identity resolution, profiles, and activation capabilities. It offers extensive sources and destinations, but it is less suited for traditional ELT or broader data engineering workflows.
Supermetrics offers pre-built reports and flexibility in data storage and visualization, but has limited data transformation capabilities and may have slow data refresh rates.

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.
While Segment is flexible for customer-data workflows, it is more limited outside those use cases. Custom pipelines, transformations, or complex modeling typically require external tools like dbt or a data warehouse.
Supermetrics provides flexibility in where data can be stored and visualized, but may lack advanced customization options for more technical users.

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.”
