What does the company do well? They are constantly innovating on the product and seem to release additional conversion tools often. The fact that they also have a free version is incredible - we have converted hundreds of users that way.
What does the company not do well? I don't find the admin to be incredibly intuitive. Although you can eventually find what you want, it can be confusing if you are using multiple tools or A/B testing.
What do you wish you had known about the company before using? That they would constantly prompt for you to upgrade from the free version every time you log in. Not a huge issue though and would definitely not stop me from using it.
