    High-End, App-Like Dashboards That Are Easy to Interact With

    Reviewed on Oct 02, 2026
    Review provided by G2
    What do you like best about the product?
    Sigma allows us to take our data and build app-like dashboards for our stakeholders. This makes the end product something that feels high end, while also being easy to interact with. It also allows for easy way to gather user input into the dashboards, allowing the business to define their own transformations or provide adjustments and approvals.
    What do you dislike about the product?
    The biggest challenge to Sigma is ensuring all users have the appropriate access to the data we are using. Given Sigma pushes all the querying to the underlying data platform, there can be challenges when we provide dashboard access to non-technical users who have been provided access in the database directly because they would never interact with the database directly otherwise.
    What problems is the product solving and how is that benefiting you?
    Sigma is allowing us to deliver both complex reporting and data applications for our stakeholders. In Sigma we are building a wide variety of reporting solutions that target both internal and external customers by combining data we have with auditable user input to ensure completeness and accuracy. Additionally, we can easily incorporate live data with data that is stored in excel files to create more complete reports than we could otherwise. Additionally, we are building highly sophisticated data applications that can support business processes that would otherwise take months to implement in typical technology platforms. These apps support both live data and user inputs to allow us to create the gold standard of data for our firm to come from these applications.

    Fast, Easy to Use, and Backed by Stellar Support

    Reviewed on Oct 02, 2026
    Review provided by G2
    What do you like best about the product?
    I really like the performance and how easy it is to use. It provides a solid, scalable architecture that can grow with our needs. The support we've received has also been stellar. They take our feedback seriously and help us find solutions. They are constantly launching new features and doing some fantastic things with AI capabilities.
    What do you dislike about the product?
    Sigma can be almost too flexible. There are often multiple ways to accomplish the same task, and it takes time to understand the trade-offs of each approach—especially once you start chaining them together. A lot of the overall experience depends on how your environment is architected and administered. Sigma's support team helps as much as they can, but if you have a unique architecture (one that's been challenging in other BI tools too), getting everything working smoothly can still take effort. There are also a few smaller gaps, such as Tableau's manual grouping and certain visual types, that users coming from other tools may miss.
    What problems is the product solving and how is that benefiting you?
    We had significant issues with Tableau around performance, scalability, and exporting data. Our users want both a visual experience and the ability to explore and download tabular data at scale, and they wanted better self-service. Sigma handles all of this well, so users can find answers on their own in one place instead of working around the tool's limits.

    A Strong, Collaborative Platform with Excellent Support

    Reviewed on Oct 02, 2026
    Review provided by G2
    What do you like best about the product?
    Sigma has proven to be a strong collaborative platform for our team. It’s exceptionally easy to experiment with different layouts or new ideas, and then have the rest of the team jump in right away to test those changes and share immediate feedback. The Sigma Support team has also been excellent whenever I’ve had questions or run into issues while using the platform.
    What do you dislike about the product?
    Sigma has less customization options than other data visualization platforms I've used. There are some limitations with how Sigma interacts with our snowflake data warehouse that has made us need to rethink and rearchitect the data that feeds reports that we have moved over to Sigma.
    What problems is the product solving and how is that benefiting you?
    Sigma has allowed us to open our data to a wider audience within our organization. The barrier to entry for analyzing data has been reduced with Sigma, as it is easier to access and significantly more user-friendly than our previous data platform. This frees up our team from needing to complete one-off analysis tasks for other teams in our org by empowering them to dig into the data themselves.

    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.

    Cutting-Edge AI Features, Excellent Writeback, and Responsive Support

    Reviewed on Oct 01, 2026
    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 brilliantly blends the familiar simplicity of a spreadsheet with the immense power of cloud data warehouses, making true self-service possible without having to write any SQL.

    Sigma can handle a high volume of data, and its write-back feature makes it a great tool for creating data apps—not just dashboards.
    What do you dislike about the product?
    The UI features still feel like they’re catching up to other BI tools on the market.

    Faster BI Workflows & Unrivaled Sigma Support

    Reviewed on Sep 30, 2026
    Review provided by G2
    What do you like best about the product?
    With Sigma, I can accomplish a vast majority of the BI activities needed in a significantly shorter timeframe. Beyond that, their support efforts and capabilities (live chat, dedicated resources to work through complex use cases, etc.) are unrivaled in the BI space.
    What do you dislike about the product?
    The core product's enhancements have slowed of late as they have ramped up AI support; however, the core product is already at a wonderful place regarding features and usability.
    What problems is the product solving and how is that benefiting you?
    With Sigma, we have been able to step out of the Microsoft BI ecosystem and its "old-feeling" legacy tools, leading to improved rate of development and updating as well as performance improvement getting us to insights more quickly.

    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.
