Your message needs work: they know what it is, who it's for, and why it's worth their time, but not why to pick you.

Can they tell what it solves, and who it's for?
15 could quickly tell what problem it solves and who it is for.
Do they actually want it?

Your page describes: marketing agency. They said:
15 got it right.
Four separate measures, not stages: all 15 personas answered all four questions. Each square is one persona.
Three points said the tone speaks to a marketing director peer rather than a VP needing business-case framing, reads too casual for vendor vetting, and mismatches a technical buyer's need for hard numbers. Not one of the four layers, and it does not affect the scores above or the order to fix them in.
These are 15 simulated buyers. Want 15 real ones?
Test with humansThe first is on your weakest layer, the second on the next, the third on the layer the most buyers had a problem with. Each says what to change on the page and why, with one simulated answer behind it.
Why: The Promat card says campaigns are 'schaalbaar' and 'impactvol' but never says what they produced. Put the outcome in the card: leads, reach, pipeline, launch time, with the period it covers.

“The named cases with recognisable Belgian names — Barco Cinema rebrand, Proximus landing pages, Vinçotte's "techniek naar vertrouwen" — those would tip it in, because they show scale and technical/regulated sectors”
Why: The cases describe what Umbau did but never what changed for the client. Give the starting point, the result and the timeframe, such as leads per month before and after.

“AE's "Exponentiële groei... dankzij een sterke marketing & sales alliantie" and "conversiegedreven website" is the closest thing to a relevant proof point for our lead-gen problem — but there are no numbers attached, no percentage lift, no timeframe”
Why: Readers have to deduce from 'Daar komen wij naast je staan' whether this is software or a team of people. Say it outright in the opening line.

“those could just as easily be a SaaS product's feature names, and "Umbau" as an unfamiliar name with no immediate tagline like "agency" or "consultancy" made me scan an extra few seconds”
These landed. Keep the wording when you edit around it.
The problem statement and target audience land immediately
“"Merk mist impact," "Leadgeneration hapert," "Marketingplan ontbreekt uitvoering," "Marketing en sales werken niet samen" - that's the execution gap named almost verbatim”
The boutique Belgian agency framing fits the buyer context respondents expected
“The tone does feel like it's written for someone like me: it names my actual internal problem ("Marketing en sales werken niet samen," "Marketingplan ontbreekt uitvoering") rather than generic marketing-speak, and that specificity is what made it land rather than feel like filler copy.”
Why: The line 'In ICT. Industrie. Healthcare. Overheid. Consultancy.' names sectors but shows no work in them, so a technical buyer cannot see a comparable client. Link one named case per sector with its result.

“The named cases with recognisable Belgian names — Barco Cinema rebrand, Proximus landing pages, Vinçotte's "techniek naar vertrouwen" — those would tip it in, because they show scale and technical/regulated sectors”
Why: Any agency could write that line, and the logo wall alone is read as table stakes. State what Umbau does that others do not: team size, working method, sector depth, or how fast a campaign goes live.

“The named cases with recognisable Belgian names — Barco Cinema rebrand, Proximus landing pages, Vinçotte's "techniek naar vertrouwen" — those would tip it in, because they show scale and technical/regulated sectors”
Why: Think, Create, Grow and Strengthen read as labels, leaving a buyer unsure what they actually get or when. Add the deliverables, the typical duration and who from Umbau works on it.

“AE's "Exponentiële groei... dankzij een sterke marketing & sales alliantie" and "conversiegedreven website" is the closest thing to a relevant proof point for our lead-gen problem — but there are no numbers attached, no percentage lift, no timeframe”
Why: 'Slimme campagnes die echte leads en duurzame groei opleveren' promises a result without any size attached to it. Name a typical lead volume or pipeline increase from a real client.

Why: Lead generation sits fourth in a scrolling list of eight pains, so the outcome buyers care most about looks like an afterthought. Lead with it and drop the duplicated items.

“Leadgeneration hapert") buried in a tag-cloud of pain points rather than the headline problem”
Why: The page speaks warmly to a marketing peer but gives a VP nothing to defend a budget with. One sentence with a named client and a number lets the page keep its tone and still pass vendor vetting.

“it reads more like it's aimed at a marketing director peer who'd nod along at "we duiken in de inhoud, brengen structuur" without needing a business case spelled out for them”
A deliberately adversarial read of the same answers. Each claim was checked back against what the personas said and dropped if nothing supported it.
The page proves nothing it claims, so every strength it has is decorative.
Seven of 15 respondents attacked case studies for missing quantified results, before/after metrics, timeframes and methodology, with only one client cited as carrying a hard reach figure. A clearly named problem (8 of 15) with no evidence behind the solution…
Named Belgian logos are being spent as proof and returning nothing.
Three respondents called strong logos table stakes and said a competitor with specific metrics would win; only one said the names boost credibility. Logos are carrying the evidentiary load the case studies abandoned.
The page is written for someone who already agrees, not for someone who has to justify the spend internally.
Three respondents said the tone addresses a marketing-director peer rather than a VP needing business-case framing, and reads too casual for vendor vetting. Combined with numberless case studies, there is nothing a champion can forward upward.
Buyers reached the point of decision and stalled — the page loses them at the last step, not the first.
Two respondents said absence of a reference from their own sector prevented a confident decision, and one said value was unclear without a comparable technical B2B reference. Comprehension is high (8 of 15) but conversion is blocked downstream.
Clear problem framing is the page's only functioning asset, and it is the cheapest one to copy.
Eight of 15 credit explicit problem and audience naming, and four say the boutique Belgian framing fits their context — but nothing in the themes shows a claim a competitor could not make verbatim. Differentiation themes are entirely negative or neutral.
The pain list dilutes whatever the actual offer is.
Two respondents said lead-gen improvement sits among multiple pain points rather than headlining, and found the list unfocused. A page that names the problem well (8 of 15) but refuses to rank its own value forces the buyer to prioritise for it.
Missing sector-specific proof blocks the decision to engage

“A mobility-sector reference who'd tell me the positioning work actually cut the time it takes marketing and business units to agree on a message — that's the only outcome I'd trust over a case study.”
“none of it is mobility — no logistics, transport or automotive client in the list, so I'd still want a reference call with someone in a comparable technical B2B space before signing off”
“To pick Umbau over them I'd need a healthcare-specific case with actual before/after lead numbers, not just AE from a different sector”
Named Belgian clients build credibility but are read as table stakes, not differentiation

“The named cases with recognisable Belgian names — Barco Cinema rebrand, Proximus landing pages, Vinçotte's "techniek naar vertrouwen" — those would tip it in, because they show scale and technical/regulated sectors”
“if a competing agency showed me a specific before/after metric (lead volume, campaign cadence, sales cycle time) tied to a "plan exists, execution stalls" problem like ours, that would win over generic sector-name-dropping every time”
“I picture a mid-sized Belgian/Flemish B2B agency — not a huge international network, more a well-established boutique, probably 20-50 people given the tone and the fact they're naming individual team roles”
Case studies carry no numbers, and that is the single most repeated complaint

“AE's "Exponentiële groei... dankzij een sterke marketing & sales alliantie" and "conversiegedreven website" is the closest thing to a relevant proof point for our lead-gen problem — but there are no numbers attached, no percentage lift, no timeframe”
“nothing on this page tells me how they'd get there or what changes in week one — it's all case studies (Barco, Proximus, AE) with outcome adjectives like "exponentiële groei" and no numbers, timelines, or specifics on the sales/marketing alignment piece specifically.”
“there's no number anywhere on this page — no lead volume, no time-to-market improvement, no conversion lift, nothing like what I'd need to judge Vinçotte or AE's "exponentiële groei" claim.”
“"meer dan een half miljoen professionals bereikt" for FOD Volksgezondheid is the one hard figure on the whole page, and everything else (Promat, Proximus, OVAM) is described in adjectives like "schaalbaar" and "impactvol" with no before/after metric.”
“the case studies here (Promat, Vinçotte, AE) describe outcomes qualitatively ("exponentiële groei," "meer dan een half miljoen professionals bereikt") but don't give me the operating mechanism or a number I can sanity-check”
“To win, they'd need a named metric tied to that Promat case — leads generated, time-to-market cut, or adoption rate across Etex's regional teams — because right now a competitor with one hard number beats their whole case study on relevance alone.”

“"Merk mist impact," "Leadgeneration hapert," "Marketingplan ontbreekt uitvoering," "Marketing en sales werken niet samen" - that's the execution gap named almost verbatim”
“The "Herkenbaar?" section lists the problems straight out — "Merk mist impact," "Marketingplan ontbreekt uitvoering," "Marketing en sales werken niet samen" — that's a clean list of pain points I recognize.”
“It's a B2B marketing agency, basically — they even spell out the model with "Think, Create, Grow, Strengthen": strategy/positioning, content and campaigns, lead gen, and embedding people into your marketing team.”
“Tone-wise, yes it's clearly aimed at someone like me - a marketing lead frustrated that "marketing en sales werken niet samen" and "leadgeneration hapert" - that's my exact daily headache spelled out.”
“the "Herkenbaar?" section spells out the problems directly with bullet points like "Merk mist impact," "Marketingplan ontbreekt uitvoering," "Leadgeneration hapert," and "Marketing en sales werken niet samen"”
“The tone does feel like it's written for someone like me - it's not consumer-fluffy, it names my actual internal friction”
“The "Wat we doen" section names the problem directly — "Je positionering zit verspreid over verschillende hoofden. Marketing en sales vertellen elk hun versie" — that's basically my exact situation”
“What took longer was pinning down exactly what they DO about it — that only clicked once I hit the Think/Create/Grow/Strengthen breakdown and then the case studies (Promat, Vinçotte, AE), which is where the problem-to-solution link actually became concrete rather than just vibes.”
Respondents read Umbau as a services agency, not software — but a few had to work for it

“those could just as easily be a SaaS product's feature names, and "Umbau" as an unfamiliar name with no immediate tagline like "agency" or "consultancy" made me scan an extra few seconds”
“It's the abstraction in the Think/Create/Grow/Strengthen labels themselves — words like "Grow" and "Strengthen" are vague enough to mean anything from a paid campaign to a workshop, so I only understood what they actually deliver once I cross-referenced them against the case studies further down the page.”
“It's a B2B marketing agency, not a tool or platform — they position themselves around "Think, Create, Grow, Strengthen," basically strategy, content/design, campaign execution, and embedding people with your marketing team.”
“It's a B2B marketing agency, not a software product — they talk about "Think, Create, Grow, Strengthen" and walk clients through strategy, campaigns, content, design and lead generation”
“if I was looking for a lead-gen product to buy and deploy myself, this isn't it, it's a services shop I'd have to hire and brief”

“I don't need to be reassured we'll get along, I need one hard number”
“the persona fits someone like me in terms of the problems named, but the register is a bit light/breezy for how I'd actually vet a vendor; I'd need the sales conversation to get serious fast with numbers”

15 AI-simulated personas matched to your target market. Each answered independently, without seeing your goal, the scoring criteria, or each other’s answers. Attribution is role, industry and company size only.
Every answer on this page was written by an AI model role-playing a buyer profile, scored on Wynter’s B2B Message Layers framework. The personas were sampled in code across role, industry, company size and behavioral traits; the model wrote only the answers. Scores arrive through fixed verdict categories and the counts are computed in our own code, so no number here was written by a model.
The count is how many personas cleared the bar on each question. A yes can be unhesitating or come with reservations; the scorecard counts both as a yes, and this is the only place the difference is shown. Per layer:
These answers are AI-simulated and directional. Validate anything you’re betting on with real buyers, your ICPs.
