Sigma Reviews & Product Details

I actually find the api useful and we use it to automate tasks that i used to do by hand. And honestly the speed is the best part as Sigma loads much faster than power bi which would freeze my browser. Embedding is solid too since you can mess with the css and make it look right. Pricing is simple. You pay your bill and you know what you get unlike those other tools with hidden costs. Review collected by and hosted on G2.com.

Every time we update the version something always breaks. Old dashboards just stop working or are buggy and i have to stay late fixing them. Documentation is kinda trash sometimes the instructions are just wrong. My space bar stuck now and i really need to get some dinner. Data model view is clunky and makes it hard to see how tables connect. Support is okay but they always make you send a million logs before they help. Review collected by and hosted on G2.com.

What I like most about Sigma Compute is how easy it makes working with large datasets in real time, without having to think about infrastructure or performance tuning. It automatically scales as queries get heavier, so everything stays fast and responsive even as the data grows. That lets me focus on exploring insights instead of managing compute resources, making the overall analytics experience smoother, more efficient, and dependable for everyday decision-making.

What I don’t like about Sigma Compute is that costs can feel unpredictable at times, especially for teams running heavy or frequent queries without tight usage controls. Because compute scales automatically, it’s not always clear how certain actions impact spending, which can make budgeting tricky. There’s also limited visibility into detailed compute usage, so optimizing costs often requires extra monitoring and experience. Review collected by and hosted on G2.com.

I find Sigma's ecosystem particularly impressive because it humanizes complex technology and doesn't require someone to be a 'Coding Wizard' for high-level work. I also really enjoy the spreadsheet-like interface, which makes Sigma feel like Excel. This familiarity is important because most business users know how to work with spreadsheet formulas, pivot tables, and filters, so there's no need for weeks of training. The live connection to data warehouses without needing to export data is a massive plus because it allows for real-time SQL query execution. I also appreciate how easy and comfortable Sigma is to use for beginners, making the initial setup a breeze. All these features make Sigma really accessible and powerful, especially for those who may not have a deep technical background. Review collected by and hosted on G2.com.

I don't like the performance lags with complex workbooks and the limited visual customization. If your data warehouse is slow or if your Sigma workbook has dozens of complex joins and calculated columns, you might experience loading spinners. Fine-tuning the pixel-perfect look of a chart, like specific border thickness, custom color gradients, or unique chart types, is more restricted in Sigma. Review collected by and hosted on G2.com.

I liked entering information in plain english and having it create a Chart. The AI identified some Trends, which is good enough for what we're doing. When I connected it to our AWS RedShift database, I was amazed that it did connect the first time and it wasn't a complete disaster (I fully expected it to). The non-technical users of our company are able to use this program and I am no longer bothered constantly with questions regarding reporting. Review collected by and hosted on G2.com.

This thing cost an arm and leg and the price is going up all the time because every time we actually use it. The Visualizations that it creates are very simple looking and the performance is somewhat slow as well when trying to do something moderately complex. The largest complaint that I have is that no matter what formula that I try to build into a report, the tool will never recognize it; even if the syntax is correct and I end up wanting to throw my mouse across the room.

I recently move to an area that relies heavily on Sigma for safety concern related data, Sigma allows us to filter and get information using very few details or even keywords it is super reliable to get the job done. Review collected by and hosted on G2.com.

The speed has significantly improved and the loading time and also exporting time for documents it is a lot faster now, definitely a must have tool. Review collected by and hosted on G2.com.

The platform provides extensive data connectivity that supports data-driven decision-making. Reports can be generated in multiple formats and connect smoothly with a range of data sources. It also includes strong data visualization tools, which makes it easier to interpret the data and quickly gain useful insights. Review collected by and hosted on G2.com.

Performance can drop when working with very large datasets, and the learning curve can feel steep. More guided tutorials would be helpful. Also, at times, some reports take a little longer to load. Review collected by and hosted on G2.com.

What I enjoy about Sigma most is that it has the ability to make you feel as though you are in a spreadsheet while having access to warehouse sized amounts of data. On a day to day basis, this is where I go to slice and dice metrics, check for trends and quickly develop views that my teammates can utilize without reaching out to our data team.

When I am performing modeling work flow there are times when I find the workflow to be a bit restrictive, specifically when enforcing consistency across dashboard definitions. Also as well, I have experienced some issues when dealing with very large tables and worksheets as sometimes it will take longer to load than anticipated. Review collected by and hosted on G2.com.

The best thing about Sigma is how it combines the familiarity of a spreadsheet with enormous power. It’s given me complete autonomy: I no longer depend on others for reports, and I can manipulate data and build complex dashboards directly. Review collected by and hosted on G2.com.

Occasionally, when I’m working with large volumes of data, the interface can be a bit slow to load. This is the only issue I’ve noticed so far. Review collected by and hosted on G2.com.

Sigma makes it incredibly easy to keep all my analytics in one place. I use it daily to track KPIs, monitor sales progress month over month, and quickly identify trends. The integration with HubSpot was fast and painless, making the implementation process straightforward. Their customer support team has also been excellent — quick to respond, helpful, and knowledgeable whenever I’ve had questions. The interface is intuitive, so I can easily access the insights I need without wasting time navigating complex menus. Review collected by and hosted on G2.com.

There’s very little I dislike, but occasionally I wish there were more customization options for visualizing data directly in the dashboard without exporting. Some advanced visualization tweaks require a bit of extra setup, but overall it hasn’t slowed me down. Review collected by and hosted on G2.com.

Sigma has enabled us to build intuitive dashboards which can be used by colleagues and customers alike. Having complete access control rights on a row or column basis makes this very easy to implement, and with the embedding framework available, it’s really easy to modify frames to appear exactly as intended, to allow coherent designs across our own company portal. The AI enhancements available in the tool are very impressive – from helping to write succinct formulae for data manipulation, to explaining aspects of the visualizations, having Ask Sigma on hand is really a game-changer for our users. We have also really enjoyed using the inbuilt tagging and versioning control, which allows powerful cross-team collaboration and transparency when building out our systems. The versatility of the tagging approach allowed us to put together a framework which complements our own versioning control methods using other software.

Sigma’s attentiveness and customer service generally has set them apart from many companies we have worked with – they have a multitude of different options for getting help and are available for quick calls to collaborate on best ways to approach problems. A particularly strong offer is the live chat, which I’ve used a few times.

Finally, the initial learning curve of Sigma is relatively shallow – the “quickstart” options are presented at a very good level to add value from dashboards within just a few days – and any additional features are easily found in the documentation when required. Our team were able to build a complete set of embedded analytics dashboards within just a few weeks. Review collected by and hosted on G2.com.

Although most of our experience with Sigma has been positive, there has been some limitations.

1) Working with larger datasets can sometimes be very slow; of course, this can be remedied by pushing complex calculations further upstream, but where that is not an option, the latency can be cumbersome. Some more transparency on how to utilise any cache functionality would be good.

2) Some visualisations which are standard in other BI software are not present in Sigma, for example axis breaks are not present and can limit the use of visualisations where outliers are both present and important.

3) Font sizing options can be a bit clunky. Even when selecting “auto” as the font size, when moving to different screen sizes, element sizes can be skewed and upset the design of the dashboard. Thus, care has to be taken to build dashboards which are not impacted by this.

4) Switches to control hiding or showing a given graph based on the underlying data (aside from permissions) is a feature which we would welcome. In our use-case, it’s imperative to show only the important information to our clients and not cloud our output with redundant information.

5) When exporting dashboards (for example, via PDF), there doesn’t seem to be a clear way to enforce all information to be present on the page. For example, where a table has a “scroll” feature, it would be preferable to show all of the information upfront so the PDF pages can be printed without losing any information.
