"Easiest BI Tool: Live Snowflake Data in a Spreadsheet-Like Experience"
4/5
What do you like best about Sigma?

It's honestly the easiest BI tool I've used. Feels like a spreadsheet but it's pulling live data straight from Snowflake no extracts, no stale data. Setting up the connection with Snowflake is dead simple too, works with key pair or OAuth so it's quick and secure. We use it for a bunch of things client project dashboards, migration trackers, internal trackers and it handles all of it without any hassle. Anyone can pick it up quickly, no SQL needed. Makes my life a lot easier. Review collected by and hosted on G2.com.

What do you dislike about Sigma?

Gets a bit laggy when workbooks have a lot going on lots of elements, big datasets, that kind of thing. Some of the advanced features aren't super intuitive at first, you kind of have to figure them out on your own. Not a dealbreaker but could be smoother. Review collected by and hosted on G2.com.

I like how Sigma is very user-friendly, making it easy to navigate the interface in a relatively short amount of time.

"Analysis With Sigma"
4.5/5
What do you like best about Sigma?

It’s super easy to do ad hoc analysis with the data the company already has, rather than relying on flat Excel files that need to be updated every time a new version is created. Review collected by and hosted on G2.com.

What do you dislike about Sigma?

It doesn’t include all the functionality of Excel, such as the ability to create custom subtotals or generate reports that look like they were made in Excel. Review collected by and hosted on G2.com.

What do you like best about Sigma?

What I like most about Sigma is how well the tool works. It’s very easy to learn, use, and implement, which makes it simple to get started and stay productive. It also includes some genuinely unique AI features that help scratch that itch of wanting to use AI. Review collected by and hosted on G2.com.

What do you dislike about Sigma?

Nothing really comes to mind right away. If I had to point to one potential downside, it would be the way provisioning appears to work. We haven’t implemented it yet, but from what I’ve seen so far, it seems more complicated than with other tools. Review collected by and hosted on G2.com.

"Sigma unlocks data value for our organization"
5/5
What do you like best about Sigma?

What I’m really liking about Sigma lately is how powerful the outputs have become while still being incredibly accessible.

That combination of depth and accessibility has made it much more valuable as a day-to-day tool, not just something used by a small technical group. Review collected by and hosted on G2.com.

What do you dislike about Sigma?

Nothing at the moment. I've loved everything on the roadmap! Review collected by and hosted on G2.com.
