01The problem
Your testimonials are off the books.
Marketing reports show ad spend, SEO traffic, and email opens. But the testimonial that closed the deal? Invisible. Finance treats your social proof as overhead — when it’s quietly the highest-ROI asset on the page.
Proof Impact closes the loop. Every widget impression, every quote view, every video play is tracked through to a tangible outcome — sign-up, upgrade, MRR.
