Mr. Amir Broshi, the founder of Shark CRM, worked in four different companies that implemented four different CRM systems. Despite the differences between the CRM tools that were chosen (cloud, standalone or in Outlook), the result was the same - after few months all salesmen continued to manage their opportunities in Outlook and Excel sheets. 

Eventually Amir came into the idea - let's give my team what they want - a CRM tool that works inside Outlook and Microsoft Excel. This was the birth of Shark CRM.
