Most pitch openings tell the room who you are. "Hi, I'm X from Y, and today I'll walk you through Z."
The room already knows. They opened the deck.
Try this: open with the sentence the person in row two would whisper to the person next to them, halfway through, after the first slide. The line that names what's actually at stake for them.
When you name that out loud in the first ten seconds, you've earned the next minute. Until then, they were going to give it to their phone.
