Slack's scalability is massive, and there are companies out there with hundreds of thousands of users. If you're talking about the free version, it is limited in its capabilities. But the enterprise edition of Slack can scale absolutely massively.

The solution is scalable. It is a lightweight application. Around 10,000 employees are using this solution in our organization.

I rate the solution’s scalability a nine out of ten.

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.

Everyone in our company, approximately 1,300 employees, is using Slack.

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. 

For my use case, I would rate the scalability a nine out of ten. Other than the limited issue of searching for files, I didn't find too many issues. But overall, it was highly scalable and served its purpose well.

Our organization was small. It was about 25 people. So everyone was using it, and we had clients and partners as well. So we had around 30 to 35 people using Slack across our organization and external contacts.

I rate the tool’s scalability a nine out of ten.

We have 200-300 solution users in our organization. I rate its scalability a seven out of ten.

There are around ten end-users in my company using this solution. There is only one administrator for the solution.

Slack is a scalable solution. About 500 to 600 people are using Slack in our organization.

I rate the solution’s scalability a ten out of ten. All 150 people in my organization use the product.

I would rate the solution's scalability a nine out of ten. My company has 60 users for the product. 

The tool is scalable. We have 20 users in our organization. Only some people in the organization do R&D work.

The tool is perfectly scalable. The whole company uses it. We have around 1000 users. My colleagues at IBM have an even larger installation that works quite well.

I haven’t seen a lack of scalability. It seems like it would be easy to expand.

Most of our colleagues use the solution. We have around 100 people on the solution.

Almost ten to fifteen people in my organization are using the solution. The product is scalable.

I would rate the solution's scalability an eight out of ten. My company has 30 users for Slack and we plan to increase the usage in the future. 

It can be scaled very easily. We have about 20 people who use this solution.

The scalability is okay.

This is a very scalable solution.

Around 20 users are using Slack in our organization, and we have plans to increase the usage.

Slack is a scalable solution, but not every organization can afford to maintain it. I rate Slack an eight out of ten for scalability.

I rate Slack a seven out of ten for scalability.

The solution is scalable. As more and more people join the organization, they are able to use the tool.

As a user, I have not had problems with scalability. I am part of a small group that makes use of slack but that doesn't mean that it isn't widely used in the company.

It is a scalable solution. A few thousand users are using the solution presently. 

The solution is scalable and can accommodate thousands of users. I didn't see any problem with scaling. My company has 1500 users for the product.

Slack is scalable. 

The solution is scalable. We are a huge team. We’re about 40 people. All of us use it seamlessly. It achieves our objective as a small team.

This is a scalable solution. 

We did have scalability issues. If you are on the free plan, you are only allowed 10,000 messages before everything is archived. This is a big problem for an alumni group which I am a member of that uses Slack.

Our messages are archived every two weeks, which makes it challenging to search for former conversations.

The price of using Slack would be $30,000/year for that community, which I think is quite steep.

Its scalability is evident in its ability to handle a varying number of users, channels, and integrations, making it suitable for businesses of different sizes and complexities. I would rate it eight out of ten.

The solution is scalable. We have 150 users in our organization.

The engineers in their department use Slack. Around 50 engineers use Slack.

We are only using the free version so I do not really know about the scalability.

We have 300 users and daily, there are 60% to 70% of them using it.

We are using the free version, which only keeps a limited number of messages archived. As our team has grown, we go through this archive allotment fairly quickly.
