The 5-Second Verdict: Auditing Nubank's Value Prop Anatomy
Objective: Score a homepage hero statement against the 4-part value prop anatomy (Who/What/How Different/Proof Anchor) and the 5-second test, then flag exactly which component is missing.
You're a contract copy auditor. Nubank's regional marketing lead wants a second opinion on a new homepage hero line before it ships to 48 million customers across Brazil, Mexico, and Colombia.
Break the given hero statement into its four anatomy components, run the 3-question 5-second test on it, and write the single highest-leverage fix.

The process
2 steps
Step 01 of 02
Every high-converting value prop names a specific Who, a specific What (outcome, not mechanism), a How Different, and a Proof Anchor. Missing any one of the four weakens the whole claim.
The draft hero line reads: 'Banking that just makes sense. Trusted across Latin America.' Which of the four anatomy components are present, and which is missing?
Procedure
- Paste the hero line into row 1 of the sheet
- Tag each anatomy component present with the exact phrase that carries it
- Mark any component with no supporting phrase as MISSING
- Write a one-line verdict: which missing component is costing the most clarity
Who: MISSING (no named segment)
What: partial ('makes sense' is not an outcome)
How Different: MISSING (no stated alternative)
Proof Anchor: partial ('trusted across Latin America' has no number)
Verdict: Who and How Different are both absent, the line could describe any bank in the region.Healthy
At least 3 of 4 components carry a specific, checkable phrase, e.g. a named segment, a stated outcome, an explicit contrast, or a real number.
Unhealthy
2 or fewer components are present, or every component is an adjective ('simple', 'trusted', 'modern') with no specific noun or number behind it.
What this means
A hero line that scores 2/4 or lower will pass a founder's read (they know the context) but fail a stranger's 5-second read, which is the only audience that matters on a real homepage.
So what do I do about it?
| Symptom | Action | Effort |
|---|---|---|
| Hero line has no named Who | Add the specific customer segment the homepage traffic actually converts best from (e.g. 'first-time credit card holders') | 30 min |
| How Different is missing entirely | Name the alternative being replaced (e.g. 'without the paperwork of a traditional bank') | 30 min |
Step 02 of 02
The 5-second test asks three fixed questions: what does this do, who is it for, why choose it over the alternative. Fewer than 4 of 5 strangers passing all three means the value prop fails.
Given the anatomy gaps you just found in step 1, predict which of the 3 test questions strangers will fail, and why.
Procedure
- List the 3 fixed questions in rows
- For each, predict pass or fail based on the anatomy gaps found
- Write the specific reason tied to the missing component, not a general impression
Q1 What does this do? PASS, 'banking' is unambiguous. Q2 Who is it for? FAIL, no segment named, could be anyone. Q3 Why choose it? FAIL, no stated contrast with traditional banks or other neobanks.
Healthy
The prediction traces directly back to a specific missing anatomy component, not a vague 'it feels weak' judgment.
Unhealthy
Predicting all three questions will pass because the line 'sounds fine', the most common founder blind spot the lesson warns about.
What this means
2 of 3 predicted fails confirms the audit: this line needs a rewrite before it goes live, not a tweak.
So what do I do about it?
| Symptom | Action | Effort |
|---|---|---|
| 2 or more questions predicted to fail | Do not ship the line, rewrite using the Who and How Different gaps identified in step 1 first | 30 min |
Final deliverable
A completed anatomy + 5-second-test scorecard for the given hero line, with the single highest-leverage fix written as one sentence.

Who: MISSING | What: partial | How Different: MISSING | Proof Anchor: MISSING Predicted 5-second fails: Q2 (who), Q3 (why choose it) Top fix: name the segment (e.g. 'growing support teams') and the contrast (e.g. 'without a 6-month implementation').
Success criteria
You're done when you can:
- Correctly tags all 4 anatomy components as present, partial, or missing with the exact phrase cited
- Predicts 5-second test pass/fail per question with a reason tied to a specific missing component
- Writes one fix that targets the single highest-leverage gap, not a full rewrite of everything
