We use the tool for project collaboration within our team. It helps us manage our daily activities. We've also integrated Slack with other tools to schedule our meetings. I'm unsure if we're currently using a professional or standard license, as there may be some limitations. Overall, we're utilizing it mainly for collaboration purposes.
Business Development and Product Owner at wrightia
A collaborative tool that helps to manage daily activities
Pros and Cons
- "Nowadays, we don't need to visit an HR portal. Our marketing and human resources teams directly share details about birthdays, upcoming events, and important dates in Slack. Whether it's a training event, a company-wide gathering, or a social event, all the information is shared there. This keeps us all updated."
- "We could see improvement in Slack by having an integrated meeting tool. Currently, we rely on third-party integration tools like Zoom to schedule meetings. It would be much more convenient to schedule meetings directly within Slack without additional integrations. It needs to have calendar and CRM integrations as well."

Nowadays, we don't need to visit an HR portal. Our marketing and human resources teams directly share details about birthdays, upcoming events, and important dates in Slack. Whether it's a training event, a company-wide gathering, or a social event, all the information is shared there. This keeps us all updated.
It's very easy to share files in Slack. We need to drag and drop or upload them. The tool's mobile application experience is user-friendly.
What needs improvement?
We could see improvement in Slack by having an integrated meeting tool. Currently, we rely on third-party integration tools like Zoom to schedule meetings. It would be much more convenient to schedule meetings directly within Slack without additional integrations. It needs to have calendar and CRM integrations as well.
One of the things that could be improved is when you are writing; if you press enter, it automatically sends the message. Sometimes, that happens when you want to add a paragraph inside the Slack tool. You can use the Macintosh command function to move to another part.
Sometimes, it's not easy to delete messages. I'm unsure if you have a specific timeframe to delete.
For how long have I used the solution?
I have been using the product for three years.

842,767 professionals have used our research since 2012.
What do I think about the stability of the solution?
The tool is quite stable, but it has bugs and glitches.
What do I think about the scalability of the solution?
The tool is scalable. It has been constantly improving. My company has a total of 75 users. However, only 43-44 users use it daily. We have an engineer and a manager to maintain it.
How are customer service and support?
I haven't contacted technical support yet.
How was the initial setup?
The tool's deployment is easy.
What's my experience with pricing, setup cost, and licensing?
The tool's pricing could be cheaper.
What other advice do I have?
The search functionality in Slack is currently limited for me due to my Slack license. I have a history limitation where only one month of history is available. Once the deadline passes, everything is deleted, so I cannot access older or former messages. I rate the overall product a seven out of ten.
Disclosure: I am a real user, and this review is based on my own experience and opinions.
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.

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

The product is not difficult to use. Overall, I rate the solution a nine out of ten.

Manager at a computer software company with 1-10 employees
Suitable for small companies and stable solution
Pros and Cons
- "Slack is a very stable product."
- "The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM."
What needs improvement?
The reason we are considering other products is because of integration. It doesn't integrate with CRM or ERP. We worked with Microsoft Exchange and we worked with CyberArk. We have what we need, so we don't require Slack anymore. But I think it's a good product.
The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM. We have more specific needs now. Slack lacks in certain integration.
For how long have I used the solution?
I have been using this solution for two years.
What do I think about the stability of the solution?
Slack is a very stable product. However, with the free version, we only have limited message history access in the free version. But overall, it's a good product and a good solution.
What do I think about the scalability of the solution?
There are around ten end-users in my company using this solution. There is only one administrator for the solution.
How was the initial setup?
The initial setup was very easy.
Which other solutions did I evaluate?
Slack is a good product in its free version, but currently, we are integrating it with VM-sharing solutions like Dolibarr. We are also exploring other products similar to Slack. So, in about a month, we will be moving towards these new products and won't be using Slack anymore.
However, until now, for the past two years, it has been a good product.
In the new CRM RFP, we plan to use Nextcloud. We also use SysTrack, but it's free. That's how our organization works. We have our own server, etcetera.
So, the only problem is we could not integrate it with our new solutions.
What other advice do I have?
I would definitely recommend Slack for small companies. For medium and large companies, I'm not sure. Maybe there are integrations available in the premium version of Slack. Otherwise, it is a very good product.
Overall, I would rate the solution an eight out of ten .
