A reviewer on G2 said:
Overview
Blendo is a cloud-based ETL service focused on collecting data from SaaS tools, particularly marketing, analytics, and CRM platforms and loading it into data warehouses and BI tools. It offers quick setup, automated schema updates, and analytics-ready data models designed for business teams.
Fast setup for popular marketing, CRM, and product analytics connectors.
Supports incremental syncs and automatic schema updates.
Provides analytics-ready metrics models (e.g., MRR, CAC) and optional pre-built dashboards.
Narrow connector catalog focused mainly on marketing and analytics tools.
Only basic transformation support—complex transformations require warehouse or BI tooling.
Pricing increases with more connectors or higher sync frequency.
Blendo Pricing:
“Blendo’s turnkey dashboards and consolidated metrics saved us weeks of manual work—data from all our marketing tools was in BigQuery overnight.”
“Limited customization: cannot define complex transformation logic beyond basic mappings and formatting.”
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 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 typically starts around $100/month for a limited number of sources and scheduled syncs. Additional connectors and higher-frequency syncs increase the cost. The free tier supports limited testing.
Hevo offers clear, tiered pricing and a generous free tier, but costs can rise quickly with increased event volume or more advanced usage.

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.
Supports simple field mappings and offers a SQL-based post-load transformation option, but lacks scripting or complex transformation workflows. Best suited for straightforward analytics pipelines.
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.”
