Real World Trial
Letter of Intent
Prospects, external customers, or partners are presented with a non-binding document outlining a value proposition or specified conditions and asked to sign it. The signed document serves as external evidence of their intent to purchase, collaborate, or commit, validating assumptions about demand and willingness to engage without requiring a full, binding contract.
