Testimonials
Use a testimonial only with the person's written consent, and show what makes it believable: their role, their company and where they are.
“What changed for them, in their own words.”
“A second one, from a different kind of client.”
“A third, about the sponsor's side: what they received and how it helped.”
Outcomes
Where a before-and-after measure can be shared responsibly, put it here. Where it cannot, leave this section out rather than inventing one.
