I like how easy it was for us as an agency (and even more so internally) than other systems out there - It's intuitive & super fast! The system allows you can customize everything from your CRM down through all of our various platforms/tools. Our team has been able use this platform since day one without any major issues or problems. We've had several account managers onboard over time but they have never once encountered anything which would hinder them using these wonderful products!! There are no downsides about what my colleagues at work know about iceberg either :) Their support staff also happens not be very knowledgeable when speaking english outside US times zones if ever needed assistance during business hours. They're always quick though whenever i need help via Live Chat within those 4 hour window periods. A bit pricey compared some others options around but honestly worth.
