Both sell a help-desk-agnostic AI agent layer rather than a ticketing system, and both make a buyer request a quote to learn the price.
Same overlay posture and the same outcome-shaped bill, without a parent company that also sells a competing help desk.
Another agent layer sold on outcomes rather than seats. The comparison turns on whether either vendor will define the outcome in writing.
Fin sold standalone also runs on other help desks, and publishes a per-resolution price with a written definition of what it bills for. Forethought publishes neither.
Zendesk owns Forethought and still sells it for competing stacks. Buying the help desk rather than the overlay is the other half of the same decision, and Zendesk publishes a $1.50 per automated resolution rate where Forethought publishes nothing.
