Sigma Makes Snowflake Analytics Easy with a Spreadsheet-Like, Collaborative Interface
Reviewed on Oct 01, 2026
Review provided by G2
What do you like best about the product?
Sigma combines the familiarity of a spreadsheet with the power of an enterprise analytics platform, making it easy for both technical and non-technical users to work with data. The seamless integration with Snowflake allows us to analyze large datasets without having to move or duplicate data, while the self-service capabilities enable business users to create reports, dashboards, and ad hoc analyses with minimal IT support. Sigma's collaborative features, intuitive interface, strong governance controls, and ability to deliver both detailed operational reporting and executive-level insights have made it a valuable tool for actuarial reporting and data analytics.
What do you dislike about the product?
While Sigma is a powerful platform, some advanced reporting and visualization requirements may require additional configuration or a deeper understanding of the tool. Users transitioning from highly specialized BI platforms may find certain advanced visualization capabilities less extensive than dedicated dashboarding tools. However, these limitations have generally been outweighed by Sigma's ease of use, flexibility, and strong integration with Snowflake, making it an effective solution for most reporting and analytical needs.
What problems is the product solving and how is that benefiting you?
Sigma enables our business users to access and analyze Snowflake data without relying heavily on IT teams. It has helped us speed up reporting, improve data accessibility, and make faster, more informed business decisions through self-service analytics and reporting.

Review provided by G2
What do you like best about the product?
From a product perspective, they try to be on the cutting edge, offering numerous AI features and workbooks as code. Writeback is also great. They also have great support and take recommendations we offer seriously and help us find solutions.
What do you dislike about the product?
They feel somewhat limited in what you can do visually. Some parts of the UI can also be a bit challenging to figure out, and it takes extra time to understand where certain options or settings are.
What problems is the product solving and how is that benefiting you?
It’s helping us create workbooks faster than ever by using workbooks as code. Being able to easily build data apps through input tables has also let us quickly create applications that we previously would have needed to build through other means.

Sigma: Simplifies Financial Data Management
Reviewed on Sep 30, 2026
Review provided by G2
What do you like best about the product?
I like how Sigma automates what used to be manual tasks, transforming external Excel work into a comprehensive and single source of truth. I appreciate the direct access it provides to our data lake and how it manages write-back forms and budget management with ease. It stands out as a financial BI tool that allows me to cut and slice data effectively. I find its general UI straightforward once I learned it and enjoy the accessibility it offers. The MCP connection is a key feature for me, enabling efficient data reporting and storage in a more private location. The initial setup was very easy too.
What do you dislike about the product?
Some of the visuals feel too simplistic. Even though I can use custom plug-ins, I dont feel it offers the same level of polish as a first part visualization UI and I wish it was more expanded of a visualization offering.
What problems is the product solving and how is that benefiting you?
Sigma automates manual reporting, provides data lake access, AI-enabled quick analysis, and BI tools for data slicing. It turns Excel files into a single source of truth, enhancing ease and accessibility.

Sigma’s Easy-to-Use Reporting with Best-in-Class User Chat Support
Reviewed on Sep 29, 2026
Review provided by G2
What do you like best about the product?
I love the usability of the system. It is so easy for non-tech oriented people to pick up and use and to even join and create their own reports and dashboards.
Sigma also has an unbelievably great "user chat". Most systems don't help their users to the extent of all of their questions, but the help center that Sigma has is the best I have ever seen, they have so many incredibly knowledgeable agents that figure out your problem in a timely manner every time.

What do you dislike about the product?
The performance/loading of workbooks and very large datasets sometimes lags when there is a lot of dating that is being loaded, or memory is being used up by another application such as zoom.
What problems is the product solving and how is that benefiting you?
Sigma makes our data accessible to everyone in our company and gives them an easy way to download, embed to clients, or use themselves for KPIs. It is also great to integrate with slack for exports and seems like there will be some AI workbook creation in the future - which sounds very exciting.

Raising the bar for traditional BI platforms
Reviewed on Sep 29, 2026
Review provided by G2
What do you like best about the product?
Sigma has been an innovator and disruptor in a BI space that has become fairly conventional, with tools like Tableau and Power BI no longer feeling as progressive as they once did. As a Snowflake customer, the integration has been excellent, with a direct connection to the warehouse that has proven to be much faster than our experience with Tableau. Their approach, positioning the platform as a true data analyst tool where users can explore data directly in the UI and then build a full data app around it, is a refreshing take on the traditional BI model. Their input tables are excellent and open up a lot of possibilities for what can be built. They are constantly shipping new features, and their approach to integrating AI has been genuinely impressive. Their customer support has also been outstanding from the start, very accommodating during the initial onboarding, and they have continued to be just as supportive through every buildout since.
What do you dislike about the product?
Wish they had a dark mode on their UI. There is some table schema syncing from the data warehouse that can be a little unpredictable at times.
What problems is the product solving and how is that benefiting you?
Sigma has solved our business's need for interactive data applications that are highly customizable, efficient, and robust, all without requiring a long build-out time and a whole backend team to manage.

What do you dislike about the product?

With that being said, I greatly appreciate Sigma listening to my team's feedback about these features in attempt to make them better fit our needs.
