The lesson
In an update to backers, name who each ask is for and when it is due, and say up front that none is money.
A 1903 investor update rebuilt as a deck by Pitch Unfairly. The cover says "December update: it flies." The asks slide is headed "Three asks this month, none of them money." Three cards are tagged "FOR FATHER", "FOR ANYONE" and "FOR KATHARINE", each with a due line: "TONIGHT", "BY SPRING", "ONGOING".
Skip the period typography and the paper textures. Keep three asks maximum, each with an owner and a date.
