We use Slack mainly for internal communication and some file storage and document storage.

What is our primary use case?
What is most valuable?
The most valuable features of Slack are communication and its ability to create hidden, private, and open groups.
What needs improvement?
The solution's user interface is not very good and changes very often. Some features, like starting a conversation with a specific person, are difficult to find. Slack's search functionality is easy to use, but it is not easy to filter the results.
For how long have I used the solution?
I have been using Slack for three and a half years.

842,296 professionals have used our research since 2012.
What do I think about the stability of the solution?
There was a problem in the solution's latest update, but it has been stable for a long time.
What do I think about the scalability of the solution?
It's very easy to scale the solution. You just have to add more people to the platform, and that's it.
Which solution did I use previously and why did I switch?
We have previously used the free Google Chat, which was free for us since we have the Google workspace. Slack has many features that are not provided in Google Chat, such as creating group and private chats.
How was the initial setup?
The solution's initial setup is very easy. You just have to download the system and make some configurations.
What's my experience with pricing, setup cost, and licensing?
The solution has lots of competitors in the market. Slack is not the cheapest solution, but that's okay.
What other advice do I have?
We have integrated Slack with Obsidian and Google Docs. The solution's integration is a good feature. Slack is a good communication tool, but it takes time to get used to it every time it changes the user interface. You may not find what you are looking for at some point because the interface has changed.
Overall, I rate the solution an eight out of ten.

Principle Product Manager at a healthcare company with 10,001+ employees
A versatile and highly scalable collaboration platform that excels in facilitating communication, document sharing, and integration with various tools
Pros and Cons
- "It offers customization options for various applications, including integrations with Zoom for video calls and a wide range of other integration plugins."
- "It would be highly advantageous if it could incorporate calendar information from sources like Outlook or Gmail, providing users not only with meeting schedules but also a comprehensive daily agenda view."
What is our primary use case?
I used it for managing competition-related matters, as well as for handling announcements regarding new products or services. It was also a go-to platform for tracking logs related to ticketing and service issues that required urgent attention, as well as for internal tasks like software deployment and operationalizing services promptly.
What is most valuable?
One of the key benefits is the ability to easily share large video files and documents without any limitations. It also integrates with ticketing systems like Jira, allowing you to add plugins, such as Outlook, to streamline collaboration with emails. It offers customization options for various applications, including integrations with Zoom for video calls and a wide range of other integration plugins. This flexibility in integration is a significant advantage. You can segment your user base into different channels based on shared access, ensuring efficient communication. One recent noteworthy feature is the collaboration space, known as Slack Canvas, which enables users to share and edit documents collectively.
What needs improvement?
It could further improve by expanding its integrations to include conference platforms, such as Atlassian and its products. Integrating with platforms like Medium for article sharing and tagging, as well as LinkedIn for publishing posts and connecting them to Slack, would be beneficial. It would be highly advantageous if it could incorporate calendar information from sources like Outlook or Gmail, providing users not only with meeting schedules but also a comprehensive daily agenda view.
For how long have I used the solution?
I have been using it for four years.
What do I think about the stability of the solution?
While downtime occurrences are not very frequent, there have been a few instances when we experienced outages on certain days. Overall, it is relatively stable compared to some other solutions.
What do I think about the scalability of the solution?
It is a highly scalable solution, given that over ten thousand daily users rely on it for their work. As the user base grows, managing channels can become overwhelming, and maintaining them can be a significant challenge in such cases. It may require a minimum team size of around thirty to forty people or more to manage it effectively.
How are customer service and support?
We don't interact directly with Slack; instead, we rely on our internal support teams for any issues.
Which solution did I use previously and why did I switch?
We used Microsoft Teams previously. While Slack offers numerous advantages over Teams, the one area where it could improve is in providing a more robust system for document collaboration and organization, similar to the functionality found in SharePoint.
How was the initial setup?
I do not have insight into the enterprise-level installation process, but accessing it privately is straightforward. You typically receive an invitation, a secure password, or an order code, allowing you to join the designated Workspace. Once you're part of that Workspace, you gain access to various internal channels, which is a significant benefit.
What's my experience with pricing, setup cost, and licensing?
When it comes to pricing, it is on the expensive side.
What other advice do I have?
I would rate Slack at around eight out of ten. It's a pretty decent platform that many startups and new companies prefer today, especially for larger audiences. One of the drawbacks or areas for improvement is the learning curve users from Microsoft-based products like Link, Skype, or Teams might face when trying to adapt to Slack's architecture. Slack's structure is quite different, and it can take some time for users to become acclimated to this new orientation. Once users overcome this learning curve, it proves to be a robust and highly effective tool that can benefit many users.

Pros and Cons
- "The portal is at its best version now."
- "Sometimes, the servers are not available."

I use the solution to communicate with the developer community. If I have any issues, I reach out to them for troubleshooting. I also use the product to know about upcoming tool upgrades. We use the solution as a community to reach out.

The portal is at its best version now. There shouldn't be any changes. The solution provides two-factor authentication. The integrations are good.
What needs improvement?
Sometimes, the servers are not available. It is rare, but it happens.

What is most valuable?
Slack is a very collaborative tool that makes it easier for me to communicate with the onboarding and billing teams.
