Proof Builder™
Part of Compound to 30™

From the Case Study System™ · No‑Fluff Friday Issue 14

Turn one client win into three ready-to-post proofs.

Most wins get told once, in a DM, and never again. Proof Builder runs the raw material through the same four-field structure — starting point, what they did, what changed, what doubt it answers — and hands you back a full case study, a one-line social post, and the objection it quietly kills.

01Starting pointWhere they were stuck, in their own words.
02What they didThe specific action or system that moved them.
03What changedThe result — a number, a feeling, a habit.
04Doubt it answersThe objection this proof quietly kills.

Paste the raw win

A DM, a call note, a testimonial, a voice-note transcript — whatever you've got, however messy.

Nothing here is saved on our end. Once you close this tab, it's gone — copy your outputs into your own Proof Shelf before you do.

Free to use — this runs on Compound30's own AI, not your account. No Claude or ChatGPT login needed.
