Six ways to pressure-test
a B2B campaign.

WhyUser is one of them, and it does not win every row. Here is what each method is best at.

Request access How to evaluate a method

Simulation

~30 min

Which role vetoes, which handoff breaks, what proof is missing.

Internal review

~2 weeks

On-brand, legal and typo-free. Not why a stranger leaves.

A/B test

4 to 6 weeks

What actually happened, after the budget is spent.

The one-screen version

Each method answers a different question.

The costly mistake is picking a tool for a question it was never built to answer.

Method	The question it answers	Time	Fails when
General AI assistant	Is this copy any good?	Instant	You need the same answer twice, or a committee
Internal review	Is this on-brand, legal and typo-free?	~2 weeks	Everyone in the room already believes in the product
Buyer panel	Does this land, in these words, with this person?	12 to 48 hours	You need committee handoffs, or eight iterations
Build it yourself	Can we own this internally?	A weekend, then forever	Month two: determinism, calibration, and no track record
A/B test	What actually happened on live traffic?	4 to 6 weeks	You lack the volume, or the budget is already spent
WhyUser	Which role vetoes, which handoff breaks, and what proof is missing?	~30 min	You need copy written, human quotes, or legal sign-off

What makes WhyUser different

Four things a measurement has to do, and two things B2B needs.

Ask any tool on this page, including us.

01 · Repeats

Same page in, same answer out.

Fix one section, re-run, and only that section can move. So you know whether your fix worked.

02 · Shows its source

Every quote traced to a real page.

Checked against the page it came from, and you are told who wrote it.

03 · Reads like your buyer

Scans, hunts, abandons. Never patient.

Distracted, skeptical and ideal, with motivation, familiarity and skill mixed to match your channel.

04 · Remembers

Your 10th run is better tuned than your 1st.

Every finding graded HIT or MISS against what happened, and the result carries forward.

05 · Simulates the committee

B2B buyers decide together.

Roles are computed as a graph, not averaged, so one blocking role sinks the verdict.

06 · Buyers stay current

Buyers are not files. They are feeds.

Each one re-compiles from live evidence on every run, so when your market moves, they move.

One method at a time

Where each one beats WhyUser, and where it does not.

No gate, no form.

Claude vs. WhyUser

Internal review

Your reviewers are the 3%.

Everyone in that room already knows the product. Almost none of your traffic does.

Build it yourself

The weekend estimate is correct.

The orchestration is a weekend. Determinism, sourcing and a graded record are not.

Read the comparison

Real humans, or the whole room.

A panel gives you people we cannot. It cannot put the committee in one room.
