Salesforce

CompanySalesforce
Since1999

CRM with marketing and support attached

CompanyHubSpot
Since2006
PricingFreemium

HubSpot's free CRM is a genuine product rather than a trial, and that is the strategy: get the contact database in place, then sell the marketing, sales, and service hubs around it.
