Is anyone using Hubspot Marketing automation and Zoho-CRM together?

Hi all,

I'm planning to build a data-integration app to connect Hubspot (marketing) & Zoho-CRM. 

As a Product Manager, I'm bit confused about the Problem-Solution fit of this app. I'm questioning my decision that:
  1. Is there a demand/need for Hubspot & Zoho-CRM integration?
  2. Is there any specific user-problems which are not being solved by existing integration apps?  
It would be great help if you could answer some of the above questions? Thanks a lot,
