In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.
