Overview

Equals in Short

Equals is an all-in-one GTM analytics platform that handles data sync, transformation, and analysis in a single interface. It automatically ETLs data from sources like Salesforce, HubSpot, Stripe, and SQL into a managed Snowflake warehouse, and then surfaces it in a spreadsheet-style BI layer for real-time pipeline, ARR, and other revenue metrics.

Pros

Built-in ELT: automatically syncs data from Salesforce, HubSpot, Stripe, SQL, etc.
Managed Snowflake warehouse included (no infra to maintain)
BI spreadsheet interface: combine spreadsheet flexibility with live queries
Pre-built GTM templates for pipeline, ARR, churn, and more
Real-time alerts and Slack/email pushes keep teams aligned

Cons

Primarily focused on revenue/GTM analytics—less flexible for non-revenue use cases
Custom SQL transforms require some technical skill
Pricing can be high for companies that outgrow the included Snowflake instance

Reviews & Quotes

From an Equals customer success story:

What I like about Equals

“Within a week, we had a pipeline performance dashboard up and running. Building something similar ourselves would have taken 3+ months.”

What I dislike about Equals

“Some advanced customization options (beyond the built-in GTM templates) require SQL knowledge and deeper familiarity with their Snowflake layer.”

Overview

Mozart Data in Short

Mozart Data is a managed data stack provider that bundles ETL (using embedded Fivetran/Portable connectors), a fully managed Snowflake warehouse, and dbt-based transformations under one subscription—aiming to get teams from zero to insights in under an hour without coding.

Pros

Out-of-the-box Snowflake data warehouse with connectors and dbt transforms in one package.
150+ connectors (via embedded Fivetran + Portable) configured behind the scenes so you don’t manage separate tools.
Very fast onboarding—your data stack is live in under an hour without any code.
Dedicated customer support and onboarding assistance (Mozart Assist) helps users set up and maintain pipelines.

Cons

Pricing includes both warehouse usage and data volume (Monthly Active Rows), so costs rise with scale—often more expensive than self-managed ELT at high volumes.
Less flexibility for bespoke connector logic—if a connector is missing, you must submit a request and wait for their team.
Smaller community and fewer third-party tutorials compared to standalone tools like Airbyte or dbt.

A reviewer on G2 said:

What I like about Weld

“First and foremost, Weld is incredibly user-friendly. The graphical interface is intuitive, which makes it easy to build data workflows quickly and efficiently. Even with little experience in SQL and pipeline management, we found that Weld was straightforward and easy to use. What really impressed me, however, was Weld's flexibility. It was able to handle data from a wide variety of sources, including SQL databases, Google Sheets, and even APIs. The solution also allowed us to customize my data transformations in a way that best suited my needs. Whether I needed to clean data, join tables, or aggregate data, Weld had the necessary tools to accomplish the task. Weld's performance was also exceptional. I was able to run large-scale ETL jobs quickly and efficiently, with minimal downtime via a Snowflake instance and visualization via own-hosted Metabase. The solution's scalability meant that I could process more data without any issues. Another standout feature of Weld was its support. I never felt lost or unsure about how to use a particular feature, as the support team was always quick to respond to any questions or concerns that I had. Overall, I highly recommend Weld as an ETL solution. Its user-friendliness, flexibility, performance, and support make it an excellent choice for anyone looking to streamline their data integration processes. I will definitely be using Weld for all my ETL needs going forward.”

What I dislike about Weld

“Weld is still limited to a certain number of integrations - although the team is super interested to hear if you need custom integrations.”

Pricing & Affordability

Side-by-side

Equals

Pricing is custom and scales with data volume and Snowflake usage. While it includes a managed Snowflake instance (removing infra overhead), costs can rise quickly once usage grows beyond the base tier.

Mozart Data

Mozart’s bundled pricing (data volume + warehouse compute) starts at ~$1,000/month for small usage, which can be competitive for teams that value time saved over cost. However, high-volume users may find it pricier than DIY stacks.

Weld

Weld offers a straightforward and competitive pricing model, starting at $79 for 5 million active rows, making it more affordable and predictable, especially for small to medium-sized enterprises.

Flexibility & Customization

Side-by-side

Equals

Users can drop into SQL when they need custom transformations or advanced modeling. While most teams rely on the built-in GTM templates, the platform is extensible via SQL and custom Snowflake functions for deeper bespoke analysis.

Mozart Data

While Mozart Data handles most common use cases seamlessly, it limits custom code in pipelines. Advanced users can still bring their own SQL or dbt models, but building new connectors requires raising a request—no self-serve SDK.

Weld

Weld offers advanced SQL modeling and transformations directly within its platform with the help of AI, providing users with unparalleled control and flexibility over their data. Leveraging its powerful AI capabilities, Weld automates repetitive tasks and optimizes data workflows, allowing teams to focus on getting value and insights. Additionally, Weld's custom connector framework enables users to build connectors to any API, making it easy to integrate new data sources and tailor data pipelines to meet specific business needs. This flexibility is particularly beneficial for teams looking to customize their data integration processes extensively and maximize the utility of their data without needing external tools.
