Sigma makes my life way easier and impresses our customers!

  • June 01, 2023
  • Review provided by G2

What do you like best about the product?
Sigma is like Excel on steroids! Very powerful, dynamic, saves me time, and I'm able to convey data driven insights directly to my customers. No code is needed to find value in Sigma. Sigma also has a very robust customer support team to answer questions whenever you need help.
What do you dislike about the product?
The one immediate challenge I've found is for a ConvertTimeZone function, it is a static function. That said, the support agent linked me to an existing ticket and they are working on a solution in the tool for this.
What problems is the product solving and how is that benefiting you?
Sigma takes all of our data, allows me to add helper fields, and then provides me automated analytics and reporting functionality that I can use to better run our operation.

Excel on Steroids

  • May 05, 2023
  • Review provided by G2

What do you like best about the product?
- The Concept: I think it's brilliant that Sigma leveraged the idea that everyone knows and understands Excel/Google Sheets. Then accessed data in Snowflake and leveraged compute in Snowflake to create a tool that allows more non-technical users to be highly effective analysts with only Google Sheets/Excel skills.

- Support: Their support is second to none, though I'm skeptical of its scalability. For now, having someone real and competent on the other side to answer questions immediately is fantastic.

- Speed of Delivery: They have a solid product and development team, as seen through their velocity of major feature releases.
What do you dislike about the product?
- Cost: It's expensive to upgrade once you're in. Recommend knowing what you'll need immediately, but negotiate for what you need in 2 years.

- Visualizations: Solid enough for rudimentary visualizations, but has a lot to catch up on, especially if they want to compete with the BI giants.
What problems is the product solving and how is that benefiting you?
As a two-sided platform in the FinTech world, some of the problems that Sigma is solving for us are:
- Making analytics and visualizations available externally for all of our customers.
- Securitizing the data to ensure that we only provide access to data that the customer should see.
- Allowing our customers to explore their data and build their visualizations based on the available data.
- Enabling our customers to export data through emails or file drops on a scheduled basis.

Internal utilization:
- Data democratization - Everyone in tech knows how to use Excel and Google Sheets. The bar to entry is shallow.

Empowering Business Users with Self-Service Analytics - My Experience with Sigma

  • February 10, 2023
  • Review provided by G2

What do you like best about the product?
I really appreciate how Sigma has made data analysis and visualization accessible to non-technical users. The platform's familiar spreadsheet-like interface and simple drag-and-drop tools allow users to create powerful reports and dashboards without needing to know complex coding or SQL. Additionally, the integration with cloud data warehouses like Snowflake means that users can work with large datasets in real-time, without having to wait for data to be moved to other platforms.
What do you dislike about the product?
One area where Sigma could improve is in terms of the visualizations offered. While the platform has a decent selection of charts and graphs, other BI tools like Tableau or Power BI offer a wider range of customization options and visual styles. That being said, Sigma is still a relatively new platform, and the team is constantly adding new features and improvements, so I'm excited to see where they go in the future.
Overall, I highly recommend Sigma to anyone looking for a user-friendly, cloud-based analytics solution that can empower business users to make data-driven decisions
What problems is the product solving and how is that benefiting you?
Sigma is solving several problems for me and my organization. First, it has enabled us to perform data analysis and reporting with greater speed, ease, and accuracy. With its intuitive and user-friendly interface, we can quickly build interactive dashboards and reports using our familiar spreadsheet skills. This has helped to democratize data access and empower more individuals across our organization to make data-driven decisions.

Second, Sigma has helped us to better manage our data by integrating seamlessly with our cloud data warehouse. It allows us to combine data from multiple sources, perform complex transformations and calculations, and generate real-time insights on large volumes of data. This has helped us to streamline our data management processes and reduce the time and resources needed for data preparation and analysis.

Finally, Sigma has provided us with exceptional customer support. The live chat support feature allows us to quickly get answers to our questions and resolve any issues that arise. The Sigma team is responsive and nimble, constantly updating the platform based on customer feedback, which has enabled us to stay up-to-date with the latest features and capabilities.

Overall, Sigma has helped us to increase efficiency, reduce costs, and make better-informed decisions. It is a powerful tool that is transforming the way we work with data, and we are excited to continue to leverage its capabilities in the future.

Changed what I thought possible for teams without expert bi users

  • February 10, 2023
  • Review provided by G2

What do you like best about the product?
This is one of those rare mythical beasts where if you try it you're going to want to buy it. It's honestly that good.

The way I describe sigma is it's a system that makes all the power, speed, flexibility and repeatability of sql based analytics accessible to any user who has moderate experience working in spreadsheet applications like Excel, Google Sheets, or Numbers.

If you can write a formula and make a pivot chart in excel, you can make a live sigma report within minutes with little to no learning required.

Taking ordinary teams with limited Business Intelligence application exposure from complete reliance on a data analyst or BI team feeding them data, to 100% self service is completely possible using sigma. The service is phenomenal, the company is constantly rolling out new features and taking an already exceptional product and making it even better.
What do you dislike about the product?
It's a newer company, so compared to say power BI or tableau there are more limited visualization options. But a) those are coming out in product updates literally by the handful and b) the meat and potatoes that blows tableau or power bi out of the water are the user interface mechanics, ease of use, speed and simplicity, and that after you do your data manipulations you can get your resulting tables sql code, with all your manipulations and formulas transformed into real sql you can take and use anywhere
What problems is the product solving and how is that benefiting you?
We use Sigma to allow team members to access data from our data mart interact tables with each other and create complex dynamic live reports and dashboards. Specifically my team uses sigma for everything from dataset building to financial analysis and P&L reporting, to KPI dashboards and Live iPhone and tablet based interactive presentations for site visits with clients.
