From our perspective, it's hard to say whether this solution is easy to scale or not. 

We have 20 users approximately. I don't see any problem taking them to 100. I have to give you an answer based on our experiences with our clients. We have clients with up to 2,000, or 3,000 users. We also have clients with five or 10 users. It is scalable. We've never had much more than 2,000 or 3000 users, and we never had any problems.

I did hear that when you get up to 10,000, or 15,000 users, it's strongly advisable to have an on-premise implementation. That helps a lot, but I can't confirm that because we haven't had any real case. It's just rumors, or people I've spoken with. 

From my perspective, with the day-to-day clients that we have, our average is about 50 to 400 users from our clients. 100% of them is cloud-based. Once they get the right platform: Amazon AWS or Azure, it's a breeze. We haven't had any issues at all. Scalability is not a problem. In fact, I hope to have more users as that helps all of us big time.

I would rate the scalability of this product an eight out of ten for very large organizations needing to scale. 

For small organizations, SMBs,  scalability is a ten out of ten. For medium enterprises, meaning 500 to 1000 users, it's probably a nine. 

For over 1000 users, that's where it's about an eight and a half. That's only because those larger organizations might also want a field service application, and Creatio doesn't have one built-in.

It is quite scalable. It is really oriented towards mid-size to large enterprise companies. That's why it's ranked high in the Gartner Magic Quadrant for sales automation.

On a typical Creatio Sales profile, we have somewhere between 30 and 100 users. They are
outside and inside sales.

Sales Creatio is a scalable solution. Sales Creatio is suitable for small, medium and enterprise businesses.

Scalability is super easy. It only takes a few clicks to add a new user.

Internally, we have about 16 users. For each of our clients, it's probably between 10 to 40 licenses.

Creatio is scalable because we can handle many more business processes. We only have around 10 users right now.

I have had no issues with scalability so far.
