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.

Overview
Informatica Intelligent Cloud Services (IICS) is a cloud-native integration platform (iPaaS) offering ETL/ELT, application integration, API management, and data quality capabilities in a unified SaaS environment. It provides hundreds of connectors for SaaS applications, cloud databases, and on-premises systems through Secure Agents. The platform supports both batch and real-time integrations, with a low-code visual designer, workflow orchestration, and monitoring dashboards.
Hundreds of SaaS, cloud database, and on-prem connectors via Secure Agents.
Unified services: ETL/ELT, data quality, application integration, API management, and B2B/EDI.
Low-code, drag-and-drop mapping designer with templates for common integrations.
Hybrid integration support through Secure Agents for connecting cloud and on-prem systems.
Pricing can be difficult to estimate due to multiple components (connectors, environments, usage).
High-throughput workloads often require premium add-ons for optimized performance.
Learning curve for advanced features such as API Designer, Data Quality rules, and orchestration.
G2 reviews:
“Some standout aspects include a user-friendly interface, scalability with a cloud-native architecture, and strong automation and scheduling features.”
“Informatica CDI is quite expensive compared to other cloud-based data integration tools, particularly for smaller organizations.”
Overview
Mozart Data is a managed data stack platform that combines ETL connectors (via embedded partners such as Fivetran and Portable), a fully managed Snowflake data warehouse, and dbt-based transformations in a single subscription. It is designed to help teams set up a complete analytics stack quickly without requiring engineering resources.
Managed Snowflake warehouse bundled with connectors and dbt transformations.
150+ connectors (via Fivetran and Portable integrations) managed behind the scenes.
Very fast onboarding—stack can be operational in under an hour.
Hands-on customer support and onboarding assistance through Mozart Assist.
Pricing scales with both warehouse compute and Monthly Active Rows, which can become costly at larger volumes.
Limited flexibility for custom connector development—requests must be routed through the Mozart team.
Smaller ecosystem and fewer third-party learning resources compared to standalone tools.
Mozart Data Reviews (G2):
“Mozart Data provided a turnkey stack where Snowflake, connectors, and transformations were already configured. We were able to start building dashboards rapidly without DevOps work.”
“Costs can increase with higher data volumes, and adding niche connectors typically requires requesting support from their team rather than configuring them directly.”
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.
The IICS web console provides a unified low-code interface for building mappings and tasks. Pre-built templates help accelerate onboarding, though data quality and advanced API features require additional learning.
Mozart Data abstracts away infrastructure management entirely. Users select sources through a simple UI, and the platform configures Snowflake, connectors, and transformations automatically, reducing setup time for non-technical teams.

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.
Pricing follows a subscription model with fees for environments, connectors, and usage. While comprehensive for enterprise needs, smaller teams may find the entry price high.
Mozart uses a bundled pricing model that starts around $1,000 per month for smaller workloads. It can be cost-effective for teams that value reduced operational overhead but may be more expensive for high-volume or highly custom requirements.

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.
Custom connectors can be created via REST or SOAP. Secure Agents allow hybrid integration with on-prem systems. Mapping Designer supports extensibility through Java or Groovy expressions.
Mozart supports SQL and dbt for transformations but restricts more advanced customization. New connectors or unsupported APIs require submitting a request, and users cannot directly create custom connectors or deploy code-based logic inside the platform.

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.”
