Use a simple before-and-after record
Before the session, write the question and current evidence. Afterward, record the options clarified, next action, owner, and review date. At the review, capture what was completed and what changed. An action not taken is different from advice tested without a useful result.
Be careful about public claims
Business outcomes have multiple causes. Describe the mentor's contribution accurately and obtain consent before publishing identifiable details or a testimonial. This public build contains no verified mentoring outcomes, reviews, or platform success statistics.
