Case Study Builder

Overview

A case study is the most versatile proof asset in B2B. It proves your product works in someone else's hands. This skill produces sales-ready case studies: one-page for quick sharing, full version for late-stage deals, always with specific metrics and real quotes.

The golden rule: a case study without numbers is a testimonial. Every case study must answer "what changed, and by how much?"

Authoritative Foundations

  • Before-After-Bridge copy formula — Structure the story as the customer's situation before, the result after, and the product as the bridge between them.
  • Joanna Wiebe (Copyhackers) — Voice-of-customer copy — Quote the customer's own words for the problem and result; interview transcripts beat marketing paraphrase.
  • Nielsen Norman Group — How users read on the web — Readers scan in an F-pattern, so lead with the metric, use subheads, and keep proof in the first screen.
