Cloud software stocks tend to fall into two categories, applications and tools. Application stocks offer a direct customer service like banking, accounting, sales, marketing, programming, etc. Tool stocks offer a backend service that a customer uses to build a cloud service.
Application Stocks:
Bill.com, PayPal, ServiceNow, Atlassian, Salesforce, Coinbase, Workday
Tool Stocks:
MongoDB, Twilio, Okta
It would be interesting to compare the performance between these two categories.
