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
FME (by Safe Software) is a data integration and transformation platform with a strong focus on spatial and GIS data. It also supports a wide range of non-spatial ETL through a graphical workspace. With support for over 450 formats and applications, FME is well-suited for organizations needing advanced spatial transformations, validation, and complex data workflows.
Supports 450+ data formats, including extensive GIS, CAD, database, and file types.
Graphical Workbench with a large transformer library for spatial and non-spatial transformations.
FME Server adds automation, scheduling, job orchestration, REST APIs, and distributed processing.
Built-in data validation and quality tools, enabling conditional checks and notifications.
Licensing costs for FME Desktop and FME Server can be high, especially for small organizations.
Primarily optimized for spatial workflows; non-spatial ETL is supported but not the main focus.
Complex workspaces can become visually cluttered and require experience to manage efficiently.
FME Product Overview:
“FME’s ability to handle complex spatial transformations and 450+ formats is unmatched. The drag-and-drop workspace builder drastically speeds up geospatial ETL.”
“Licensing can be expensive for smaller organizations. Focus on spatial means some general ETL features are less polished than GIS-specific functions.”
Overview
Hevo is a cloud-based platform for data integration and pipeline automation. It helps organizations consolidate data from SaaS apps, databases, cloud storage, and more into a data warehouse. While it emphasizes ease of use and supports ELT workflows, Hevo lacks certain advanced features like reverse ETL, extensive orchestration, and deep customization options, which may limit its utility for complex data operations.
Supports ETL and ELT workflows
User-friendly interface ideal for non-technical users
Includes a broad selection of fully managed connectors
Offers affordable pricing with a free tier
No support for reverse ETL workflows
Limited options for advanced custom scheduling
Lacks orchestration and lineage features
Minimal support for version control or complex transformations
As one reviewer on G2 puts it::
“Hevo is really good for standard pipelines, but it has some limitations for more complex use cases.”
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.
FME Workbench offers a desktop UI for visually designing data flows using Readers, Writers, and Transformers. It is powerful for spatial data but can become cluttered when handling large, complex pipelines.
Hevo’s simple UI and code-free interface make it highly approachable for non-technical teams looking to build data pipelines quickly.

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.
FME Desktop licensing typically starts around $2,000 per year. FME Server is licensed per core and can exceed $20k per core annually, making it more suitable for mid-sized and enterprise GIS teams.
Hevo offers clear, tiered pricing and a generous free tier, but costs can rise quickly with increased event volume or more advanced usage.

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.
Supports 450+ formats, spatial and non-spatial transformations, workflow orchestration via FME Server, event- or schedule-based automation, REST APIs, and strong validation capabilities.
Hevo supports both ETL and ELT, includes a wide range of connectors, and integrates with dbt Core. However, it lacks reverse ETL, advanced orchestration, and granular pipeline control.

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.
Users can embed Python, R, or Shell scripts for advanced logic. FME Server supports deployment on-prem or in cloud environments and scales horizontally. Data lineage and cataloging are not built in and require separate systems.
Hevo is built for ease of use, but its limited customization and lack of developer-focused features may not suit advanced or highly bespoke data workflows.

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.”
