Zendesk (NYSE:ZEN). Both cloud service companies remained resilient throughout the COVID-19 crisis, but I believed Veeva's wider moat, better profitability, and lower valuation made it a better buy than Zendesk.

The CRM children of Salesforce Veeva and Zendesk both offer cloud-based CRM (customer relationship management) services.
