A cold call opener that earns 30 seconds

Do your homework first, so you have a reason this person might care. Open with who you are, why you are calling them specifically, and a value hypothesis: 'Companies like yours often struggle with X; we help with Y.' Then ask a question instead of pitching. Never open with 'How are you today?' or a feature list. The goal of a cold call is a next step, not a sale.
