https://www.zoho.com/salesiq/blog/3-reasons-you-should-start-using-predictive-lead-scoring-2.html & SalesForce is now making use of their AI Assistant (Einstein) to roll out predictive lead scoring  https://releasenotes.docs.salesforce.com/en-us/spring17/release-notes/rn_sales_einstein_lead_insights.htm

Why is Zoho still stuck on a manual process of setting Lead scoring criteria rather than using Zia?
