What you do, for whom, in one sentence a non-expert can repeat.

Include the 'why now' — investors fund inevitabilities with a timing edge, not timeless ideas.

Bottom-up (customers × price), not a top-down consultancy number.

Numbers with dates. Growth rate beats absolute size at this stage.

One line per person, focused on earned advantage for this problem — not job titles.

Amount + the milestones it buys. State what the money proves, and avoid naming a valuation here — that's set in negotiation.
