Need raw feedback on this work management SaaS

Hi Folks, I am building a SaaS platform called Slam, which is an intuitive work management platform for small businesses. With the product users can manage the complete business lifecycle- calendar, pipeline, projects, team and finances. Have a quick look: www.slamapp.co I am looking for some raw feedback of the usability of the product for SMBs, how useful will it be considering the availability of few products in the similar space.
