What do you like best about Weld?

Coming from a relatively small organization, Weld has made it easy to set up and manage a data warehouse with numerous data sources. Furthermore their intiutive design has made it easy to get started with tranformation and analysis of data. With the addition of their AI tool, it is now also extremely easy to get into writing SQL, even with a very limited experience. The tool seems to be developing every day!

One key sales argument for me, was that it is an option to export your code down the road, if our data warehousing needs change in the future - thus you are never tied to the software.

In short, Weld is definitely a state of the art tool, that can help you boost the data integrity in your company within a relatively short time and without heavy cost. Review collected by and hosted on G2.com.

What do you dislike about Weld?

The product proposition in Weld has changed over the past year, which we needed to navigate within. On the other hand the pricing plans have also changed accordingly (adding an essential plan), and Weld has done their best to not affect our experience. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

Establishing a data warehouse and data ETL. Review collected by and hosted on G2.com.

What do you like best about Weld?

This is my second company where we've decided to use weld. We went from Fivetran saved 40% on a monthly basis while seven-folding our active rows. Alos, if you ahve an issue, either Weld solves it before you notice there is an issue or they responed with lightning speed when you create a ticket. Review collected by and hosted on G2.com.

What do you dislike about Weld?

Not as many connectors as Fivetran, of course. However, in the end we were able to 95 % of our connectorss with Weld. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

It's so easy to connect and fetch data from different platforms. We don't need to create a signer tap and deploy to our own services. Review collected by and hosted on G2.com.

What do you like best about Weld?

Weld really simplifies data integration and warehousing. It’s straightforward to set up data sources, and it's a great platform for building out the data warehouse. On top of that, connecting to visualization tools and pushing data back out through reverse ETL is seamless, making it a well-rounded solution. Review collected by and hosted on G2.com.

What do you dislike about Weld?

There aren’t many downsides to Weld, but if I had to point out a couple of things, the UI can be a bit glitchy occasionally (e.g., the code editor tabs). Also, the AI integration isn’t quite at the same level as tools like copilot or cursor yet. But really, these are small drawbacks in an otherwise great product. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

Weld has made it incredibly easy to bring together data from multiple sources, which used to be a time-consuming and manual process. By simplifying data integration and warehousing, it’s allowed us to centralize all our data efficiently, providing a single source of truth. Review collected by and hosted on G2.com.

They are very understanding and are quick to reply when we have questions.

We use it almost every day and it is a very crucial help to allow our data to be combined and enriched in basically any way possible Review collected by and hosted on G2.com.

What do you dislike about Weld?

Sometimes tracking how properties evolve through queries can be a big struggle and it increases debugging time within our complex queries Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

Having to manage APIs to all our tools would require an FTE and this can be saved with the help of Weld. Being able to get an idea and get started working on something within minutes helps us investigate our data in a multitude of ways despite limited resources and with little time investestment Review collected by and hosted on G2.com.

What do you like best about Weld?

The out-of-the-box connectors to common cloud based software solutions are great and the ease of implemenation is awesome. Time to data and time results drastically decreases compared to any other approach. The ability to use own BigQuery databases is great. Customer support in case of (very few) issues was good. Review collected by and hosted on G2.com.

What do you dislike about Weld?

A bit more focus on structuring and usability of complex data structures would be great. Especially if the goal is to build a layered datawarehouse this would be helpful. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

So far we had to build own integrations with all different cloud systems we and our customers use. This was a lot of time and effort spend, especially for customers with a lot of different systems. Weld ist covering most of this out of the box and also provides custom connectors for any connection not covered. Review collected by and hosted on G2.com.

What do you like best about Weld?

Easily set up connections to Microsoft Business Central, Google Big Query, Excel, Google sheets and much more with the click of a button. Weld has made an amazing job in setting up integrations to a large set of application and cloud platforms, which makes it super easy to set up connections and start gathering, managing and exploring large sets of data. Exploring the data is very intuitive and user-friendly with an AI query generator and SQL-like grammar. You can easily create views, tables and data models with data from completely different sources. Review collected by and hosted on G2.com.

What do you dislike about Weld?

It seems like there is no possibility as of now to sync data to MongoDb. You can get data from MongoDB but not insert data. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

Previously, I spent countless hours writing custom ETL scripts to aggregate data from various sources for ML models. Now, I can quickly connect to my customers data sources, transform the data, and create consistent training datasets with minimal code.

The visual interface helps to quickly validate data quality and identify potential issues before they affect model training.

By centralizing data operations, you can better track which datasets were used for different model versions and ensure reproducibility.

These capabilities have reduced the data preparation time by approximately 60%, allowing me to focus more on model development and optimization rather than data engineering tasks. Review collected by and hosted on G2.com.

What do you like best about Weld?

I love how easy it is to setup, and that they offer 'managed BigQuery' so you don't have to have our own BigQuery account. The game-changer is their AI assistant which you can use to write SQL statements from scratch accustomed to your data tables. Lastly, their customer support is the best - had to reach out due to a sync problem, and they resolved it for me in 10 minutes. Thanks, Chloe! Review collected by and hosted on G2.com.

What do you dislike about Weld?

The limit of 4 connectors for their basic plan can be a bit restrictive. Granted you can upgrade for a higher limit, I feel this needs to be higher. Review collected by and hosted on G2.com.

What do you like best about Weld?

Weld is an incredibly effective tool because it combines product simplicity with AI tooling. Weld is one of three platforms that make up our business intelligence suite, and it's never the bottleneck in getting stuff done.

Onboarding team members onto Weld takes no time at all.

The AI tooling has the full context of your data structure, which makes prompts easy to write and the results high-quality. This feature speeds up our model-building significantly.

Finally, being able to view the lineage and dependencies of models makes change management easier. Review collected by and hosted on G2.com.

What do you dislike about Weld?

We would love to have some more advanced functionality around orchestration. In some scenarios, we would like a model to have scheduled daily rules (e.g., incremental sync) and scheduled monthly rules (e.g., full table sync). In our setup, triggering the full table monthly sync requires manual action. This action takes less than a minute but is manual nonetheless. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

Firstly, in reliably extracting data from multiple sources. Then in model building.

We can lean on well written models (helped by AI), model tests, and reliable orchestation management to have piece of mind that our data is being processed as intended every day. Review collected by and hosted on G2.com.

Response from Carolina Russ of Weld

Thanks for the great feedback! ❤️ We’re glad Weld’s AI and simplicity are helping speed up your model-building and make onboarding smooth.

We hear you on the orchestration features and will definitely keep that in mind as we continue improving Weld. 🚀

What do you like best about Weld?

With Weld, we can easily gather and manage all our data from across the business, explore and create insights across departments, and activate these insights with rETLs and reporting tools. The platform is intuitive to use, and both AI support, customer service, and their continuous development are very helpful to get us through any technical challenges. Review collected by and hosted on G2.com.

What do you dislike about Weld?

The technical documentation could slightly more detailed to avoid relying on customer service, and we have a few tools that don't have a direct connector to Weld yet, but this has so far been solvable with 3rd party tools. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

Weld is making it possible for us to keep all critical data operations in one place, making it much easier to manage the data and grow the data infrastructure with the business. Review collected by and hosted on G2.com.

What do you like best about Weld?

Weld provides not only a huge selection of connectors, but also a clever custom-connector cloud function-based approach which makes the tool very flexible and easily adaptable to any needs. Moreover, the implementation is quite straightforward, and the customer support is great. Review collected by and hosted on G2.com.

What do you dislike about Weld?

The downside of Weld is there is no API to directly interact with the tool nor download your data. As a consequence, all of the models/orchestration you make in the platform stays locked there. Besides that, there is no way to connect Weld to dbt or Airbyte, for example. However, it's fair to mention they're planning to change that soon. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

Weld is an all-in-one solution. It handles ingestion, transformation, and loading. This makes everything easier when compared to stitching a bunch of tools together. Review collected by and hosted on G2.com.

Response from Carolina Russ of Weld

Thanks so much for the kind words! We’re so glad Weld is meeting your needs. The API is in the works, so keep an eye out! 😊

What do you like best about Weld?

As a consultant analytics engineer, I frequently use Weld for our clients. I appreciate how easy it is to integrate the modern data stack with this end-to-end solution. The data governance features are of great help. The data lineage in the SQL editor simplifies organisation and onboarding for new users. The custom connector enables us to ingest data from sources Weld doesn't have a direct connector from, making the tool even more adaptable. Review collected by and hosted on G2.com.

What do you dislike about Weld?

Weld has a wide range of connectors, and their engineering team strives to develop more each month. When I don't have a direct connector, I might be a bit frustrated at first but their custom connector solves this problem for the time being. Review collected by and hosted on G2.com.

What problems is Weld solving and how is that benefiting you?

I usually deal with customers who do not have any modern data stack infrastructure. Thanks to Weld's managed BigQuery data warehouse, I can quickly access the benefits of data warehouses without the hassle. I set up connectors in minutes and start modeling data, all within one tool. It has greatly sped up our processes, and our clients are much happier with the speed of delivery. Review collected by and hosted on G2.com.
