I have looked at and used Hubspot, Zoho, Marketo, and Sugar CRM. SharpSpring has an amazing support staff. They will not only get back to you quickly, they will also have a solution for you. SharpSpring is very much like a lower cost Hubspot--I liked them--with Salesforce thrown in. I am more of a strategy guy and when I had to go tactical with the start of my new agency, I had to wear a bunch of hats. SharpSpring didn't waste my time. In fact I offloaded a lot of my grunt work to the platform. It is a great robot. I love it.
