Also called LOI
A non-binding term sheet setting out price, structure, and key terms, which typically grants exclusivity.
In a sale
The letter of intent is where price, structure, and the key terms are first written down, and it usually grants the buyer exclusivity. Although it is non-binding, a term it leaves out is hard to win back once exclusivity begins. Comparing letters of intent on take-home and certainty, not on the headline, is how founders choose among them.
