My company has around 2000 users using the product. The number will rise to another 1000 once we implement the sales module. I rate its scalability a five out of ten. 

We have 5,000 to 6,000 users.

The solution is scalable. More than 1000 people use the product in our organization.

The scalability of Siebel CRM is good. It is simple to scale and I would recommend it for large enterprises.

I rate Siebel CRM a ten out of ten for scalability. More than 5000 users are using Siebel CRM in our organization.

The solution can scale well. The functionality is not affected when you expand users. It can take thousands of users. RIght now, we have 4,000 users. 

The solution is scalable. You can add any amount of load to it and it will be performing the same. My company’s total employee strength is 1500. Every single person in my company is using the tool somewhere in their operations.

Siebel is highly scalable. We've rolled out Siebel for clients with customers in the millions, so it can handle that kind of scale.

This solution is challenging to scale, especially when used on-premises. We experienced CP-usage spikes, memory-usage spikes and component crashes due to the memory limit of 4GB. 

This is a scalable solution. 

The product was very scalable. It's not a problem if you want to expand. 

It is scalable, but it eats up a lot of hardware.

We have more than 1000 users.

We have a lot of users. In the call center, we have about 2,000 agents logged into the solution. At our peak, we have over 2,500 users on it.

We really use it extensively every day. We don't have plans to increase usage, however, maybe in the future we will upgrade to a more cloud native version.

Not really apart from the features mentioned above (PIM Sync).
