I have used Civis in multiple projects for various clients. The product has been very stable from my experience. It has had only one major update so far in its lifetime which was a year ago. They are constantly adding new features and improving their products. There is nothing I dislike about this product. It's easy to use, very reliable, secure and robust. It's a great product if you want to manage your customer data. We can easily track our customers' journey and find gaps in our marketing efforts. A good option for any kind of data management or analytics. At first it might seem that it's complex, but once you start using it you'll realize how easy it is to get into.
