Short answer: we reviewed the websites of 30 B2B tech startups that had just announced a round between pre-seed and Series A, 15 from Poland and 15 from Germany and Switzerland. The average overall verdict was 5.9 out of 10. Seven sites scored 8 or 9; six scored 3 or 4. Most lose the buyer at three moments: the first screen (only 13 of 30 were clear within 5 seconds), the first click (on 9 of 30 the button did not do what it promised) and the first inconsistency (8 of 30 showed numbers or prices that did not match). What separated the best sites from the weakest most was proof, not design.
The three moments where funded startups lose the buyer
Sites rarely failed because something was missing. Something broke at a moment of intent:
- The first screen. A slogan where the value should be: the buyer cannot say what the product is or what it removes from their week.
- The first click. The button says “free” or “no account”, and the next screen asks for a phone number or a login.
- The first inconsistency. A homepage price that differs from the pricing page, or a customer result stated two ways.

| Sites scoring 3 or 4 of 10 | 6 |
| Clear within 5 seconds (4 or 5 of 5) | 13 |

How we ran the study
Sample. 30 B2B tech startups that announced a round from pre-seed to Series A: 15 headquartered in Poland and 15 in DACH (11 in Germany, 4 in Switzerland; no Austrian company appeared in the window). By stage: 6 pre-seed, 6 seed, 5 Series A or its extension, and 13 where the announcement gave the amount but not the stage.
Sources and selection. Polish companies came from MamStartup (funding category) and EU-Startups, DACH companies from EU-Startups, strictly newest first. No company was picked or skipped because of its website; every skip has a written reason (consumer apps, pure services, debt rounds, Series B or later, conflicts of interest, headquarters outside the region). Announcement windows: Poland 12 February to 30 September 2026, DACH 24 August to 2 October 2026. No guessed addresses: each came from the announcement, the company-name domain, another article about the round, or a search confirmed on the site (matching registry number, address or investors). All sites were checked on 5 and 6 October 2026.
Three layers of review, plus a fact-check.
- Content checklist. 12 criteria rated yes, partial or no in two independent passes, the second blind to the first: agreement on 324 of 360 ratings (90%).
- Visual review. The first desktop screen at 1440x900, the first two screens and an iPhone-size view, with and without the cookie banner. 8 criteria, two independent reviewers, agreement on 215 of 240 ratings (90%).
- Strategic review. The core of this article: 10 dimensions scored 1 to 5 plus an overall verdict from 1 to 10, from the point of view of each company’s buyer (role, problem, main fear when buying). Every site was walked through live: main buttons, language switcher, pricing, team, legal data, security, up to 3 case studies, freshness. We did not submit forms or create accounts.
- Fact-check. Every concrete claim was re-checked independently from scratch: 661 claims, of which 589 were confirmed, 41 partly confirmed, 27 could not be verified and 4 were wrong. All 4 were corrected before analysis.
Who did the work. Every site was scored against our fixed rubric and evidence rules. Our strategy lead analysed the results and approved the final scores.
Calibration. 3 is a typical decent site, 5 best in class, 1 a real failure. Overall verdicts: one 3, five 4s, seven 5s, seven 6s, three 7s, six 8s and one 9.
Finding 1: Proof separates the best from the weakest
What we saw. Proof averaged 3.4 of 5, the same as design. But the gap between the top sites (8 or 9) and the weakest (3 or 4) was 2.9 points on proof, the largest of all ten dimensions (design 1.5, information architecture 0.9). Proof also tracked the overall verdict most closely (r = 0.80, design 0.76); with 30 sites, read that as a pointer, not a statistical proof. A defence-tech startup with one of the best-looking sites (design 4 of 5) scored 4 of 10 overall: no company details, no team, no proof of any kind.
What the best do. They attach a named customer to a number. xorlab, a Swiss email-security company, publishes a Julius Bär case study with “+431%” SOC response efficiency and “2811 h / year” of analyst time saved, and offers: “we’ll gladly arrange a reference call, just ask”. Tequipy, a Polish company supplying IT hardware to distributed teams, shows a Booksy case with “99% Equipment delivery before the employee’s start date”.
How to fix it. Follow the proof hierarchy: a named customer with a number beats video testimonials, which beat named quotes, customer logos, partner or investor logos, then awards and press. Put the strongest item next to the hero: customer, result, time frame. If all you have are partner logos, say what the partnership proves. Or replace a logo bar with “Used by [customer] to cut onboarding from 14 to 6 days”, linked to the case study.
Finding 2: The first screen still speaks in slogans
What we saw. Only 13 of 30 sites scored 4 or 5 on “understood in 5 seconds”; 7 scored 1 or 2. Typical: a three- or four-word vision line with no category (a space company, a medtech spin-off). Sometimes the best sentence sat on a subpage: a Polish finance tool kept its strongest promise, monthly results days after month end instead of weeks, on a feature page. Polish sites did better than DACH ones (3.6 vs 3.1); many DACH deep-tech sites open with the vision instead of the application.
What the best do. Zynt, a Polish sales-signals company and the top site in the study (9 of 10), opens with “The daily list of companies that are starting to buy.” No mention of AI, and example signals sit right under the hero. Viktor, an AI employee in Slack built by Polish founders, says “Not a tool. A hire.” next to a Slack mock-up of a real task.
How to fix it. Rewrite the first screen in the buyer’s words: what it is, the outcome, and for whom if that is not obvious. “AI”, “platform” and “solution” are details. Show it for 5 seconds to someone in the target role and ask them to repeat it. Illustrative: “Intelligent automation for modern finance teams” becomes “Close your books in 3 days, not 15”, plus one proof line such as “[Customer] closed March in 4 days.” If your best sentence lives on a subpage, move it up.
Finding 3: The first click breaks the promise (9 of 30)
What we saw. On 9 sites the next screen did not deliver what the button said, at the exact moment the buyer had decided to try:
- “Free” that leads to sales. “Try for free” opened a demo-booking form asking for a tax ID and a phone number (a Polish finance tool).
- “No account” that needs an account. A payments startup promised results before signing up, then asked the user to log in after they had typed in their offer.
- Buttons that lead nowhere useful. “Get started” only scrolled the page (a German logistics startup). An address field in a hero looked like a search box but could not be typed in (a German proptech).
What the best do. Zynt: “Start for free / No card required”, backed by “No call. Signals straight away.” Viktor offers “Continue with Slack” and “No credit card required”, and the free start works. Zeit AI, a German data-engineering company for finance teams, offers a free proof of concept in 24 hours (“The first step is free”).
How to fix it. If a button says “free”, “no account” or “explore on your own”, the next screen must deliver exactly that. Otherwise rename it: “Book a 20-minute demo” is honest; “Try for free” leading to a sales form is not. Click every call to action on desktop and phone before each release.
Finding 4: Small inconsistencies (8 of 30)
What we saw. Prices: a monthly price on the homepage that does not match the pricing page, and “from” prices on the homepage that differ from the pricing page (three companies). Proof: the same customer result stated two ways on the homepage and in the case study; a case-study tile carrying another customer’s headline; an English version claiming far fewer customers than the Polish one.
Together they raise a question a CFO or procurement team will not ask out loud: if the numbers on the site do not match, why would the invoice? In a Gartner survey of 632 B2B buyers (run in August and September 2024, published in June 2025), 69% reported inconsistencies between a vendor’s website and what sellers told them.
What the best do. They make the price readable. Zynt publishes a Pilot at “$400 per month, no implementation fee”. Tequipy’s public pricing comes with a calculator headed “What you’d actually pay”.
How to fix it. Run a consistency sweep: every price, number and claim that appears more than once (homepage, pricing, case studies, languages, decks) must match. To align deck and site, see one story for pitch deck, website and sales deck; what enterprise procurement checks on your website shows how those buyers read the gaps.
Finding 5: The strongest proof is hidden or unreachable (6 of 30)
What we saw. Hidden: a named customer case study not linked from the article list or the homepage (an industrial-AI company); a regulatory licence and a space-agency contract mentioned only in blog posts (a space company). Unreachable: on one site all four customer-story tiles led to a 404 page, in both languages (a Polish fintech). Our strategy lead spotted it; a verifier confirmed it.
What the best do. Kuro, a German company building AI for general contractors, names its customer Köster with “6 Stunden gespart pro Woche pro Mitarbeiter” (6 hours saved per week per employee), backed by a video case study.
How to fix it. Make a proof map: list what you can show by the hierarchy above and check whether the strongest item sits within the first two screens. Search your blog, newsroom and research notes for proof that never reached the homepage. Click every case-study link in every language.
Finding 6: Language versions are half-done (12 of 30)
What we saw. The switcher changes the hero, then the page falls back to English; German chart labels on the English page; a Polish “version” that is in fact a short page about R&D projects; untranslated blog posts that send readers to the homepage; /de returning a 404 on a Swiss site selling into Germany.
What the best do. They write in the buyer’s professional language. Kuro uses the trade’s vocabulary (Nachtrag, Leistungsverzeichnis, GAEB, Raumbuch) and frames its promise as the buyer’s risk: contradictions become “sichtbar, bevor der Preis abgegeben ist, und nicht erst, wenn der Nachtrag kommt” (before the price is submitted, not when the change order arrives).
How to fix it. Translate the whole page natively or do not offer the language. Never send the switcher to a 404 or the homepage. If you are entering Germany or the US, see US and DACH market entry for what changes beyond translation.
Finding 7: Too long, without selection
What we saw. Information architecture and copy were the lowest-scored dimensions (3.0 of 5 each). Half the sites (15 of 30) are longer than 12,000 px on a phone, roughly 14 or more phone screens. The median was about 11,500 px on mobile; the longest ran to about 30,600 px. The usual cause: benefits repeated two or three times, a full pricing table or country list on the homepage.
The nuance. Length does not separate the best from the weakest (a 0.9-point gap; several top sites are long too). It tires buyers, but missing proof and broken promises are what make sites fail.
How to fix it. Remove repeated benefits, move full tables and country lists to their own pages, keep one main button per screen. Do this after proof and the first click.
Finding 8: Trust is hygiene. It hurts only when it is missing
What we saw. Trust tracked the overall verdict most weakly (r = 0.40): most companies are fine here. But when several items are missing at once, the site loses regardless: an anonymous hardware startup with no company name, address or team; a medtech spin-off with an empty privacy policy and empty terms.
What the best do. They let others vouch for them. Kuro quotes the managing director of GOLDBECK Technologies; xorlab offers reference calls.
How to fix it. Build the trust layer your segment expects: a team with faces, the legal entity with registry data, a security or compliance page if your buyers must pass an audit, and fresh content. Check that your privacy policy matches your cookie banner. Investors run a similar check; see what investors check on your website.
Finding 9: The cookie banner takes the first phone screen (16 of 30)
What we saw. On 16 of 30 sites, a modal or large panel covers most of the first phone screen, or the headline and button; both visual reviewers agreed on every site. It was far more common in Poland (12 of 15) than in DACH (4 of 15). About a third of the sites (9 or 10 of 30, depending on the reviewer) also show no real product in the first two desktop screens.
How to fix it. Open your site on a phone in a private window. If the banner hides the headline or the button, switch to a smaller bar. Then check that the real product shows on desktop.
What the seven best sites share
Zynt, Tequipy, Viktor, Kuro, Zeit AI, xorlab and Adaptyv Bio sell different things to different buyers in different countries. The pattern is the same: a concrete outcome in a number, a named customer behind it, and an honest, low-friction first step that does exactly what it says. None of these requires a redesign.
The scorecard: rate your own site
This is the rubric we used. Score each dimension from 1 to 5, with 3 as a typical decent startup site.
| Dimension | 1 | 3 | 5 |
|---|---|---|---|
| D1 Understood in 5 seconds | Slogan or jargon; unclear what it is | Clear what it is, but described as technology, or you must read a paragraph | The buyer can repeat in their own words what it is and what problem it removes |
| D2 Value proposition | No value, only features | Generic value (“save time”) | A concrete, measurable outcome and a clear difference from how they work today |
| D3 Fit to the buyer | Unclear who it is for, or speaks to everyone | Buyer implied, examples generic | The buyer sees their world: roles, situations, words |
| D4 Proof | None | Partner or investor logos, or customers without results | Named customers with numbers, testimonials (ideally video), case studies |
| D5 Trust in the company | Anonymous; gaps add up | Some signals, gaps that matter in this segment | Real people, legal details, security, recent content |
| D6 Path to buy | No call to action, or the promise breaks on click | Generic “Contact”, no price signal | One clear next step, price or clear process, promise kept |
| D7 Design quality | Template, stock photos, rough edges | Correct but generic | Crafted, distinctive, shows the real product |
| D8 Hierarchy and information architecture | Chaos, too long or too thin | Logical but too long or with dead sections | Every section earns its place, clear rhythm, good mobile |
| D9 Copy and localization | Generic “AI-sounding” text, errors, dead language versions | Correct but characterless, small gaps | Specific, human, consistent in every language |
| D10 Feeling and brand | Distrust or indifference | Neutral, “like everyone else” | A clear feeling that fits the price and segment |
Averages across all 30 sites ran from 3.8 (fit to buyer) to 3.0 (information architecture and copy); path to buy was 3.1. Polish sites were stronger on proof (3.6 vs 3.2), DACH sites on fit to buyer (3.9 vs 3.7).
The 60-minute self-audit
You need three people: the founder, someone from sales and someone from outside the company. Run these five steps in order and write everything down.
- 5-second test. Show the first screen on desktop and on a phone. Record what each person says the company does.
- First-click test. Click every call to action and every language switch. Note what the promise was and what actually happened.
- Consistency sweep. List every number and price. Check each against every place it appears.
- Proof map. List your proof by the hierarchy. Is the strongest item within the first two screens?
- Score. Rate yourself on the 10 dimensions above. Fix the lowest one with the biggest gap first.
The order of fixes
- Put one named proof with a number next to the hero, moving strong cases up from subpages and the blog.
- Make the first click keep its promise, or rename the button.
- Rewrite the first screen in the buyer’s words and run the 5-second test.
- Run the consistency sweep across site, pricing, case studies, languages and decks.
- Fix language versions or remove them.
- Build the trust layer your segment expects.
- Cut repeated sections and move full tables to their own pages.
- Keep the cookie banner off the headline and button on the mobile first screen.

Limitations
- 30 sites, 15 per region: patterns, not a representative picture of all startups.
- One snapshot (5 and 6 October 2026); sites change daily through A/B tests, carousels and fixes.
- Unequal windows: Polish rounds span about 8 months, DACH rounds about 6 weeks, and the DACH sample comes from one English-language source.
- Scoring is judgement; two evaluators could differ by a point, so every score has evidence and every fact was re-checked.
- In hardware, defence and medtech, public pricing and case studies are rarer; scores are relative to the segment.
- We did not submit forms or create accounts, so sales response time and the logged-in product were not assessed.
Where dp.vision fits
Everything above can be done in-house, starting with the self-audit. If you want outside help, dp.vision is a senior brand, web and product studio for funded, founder-led B2B tech, from pre-seed to Series A. One permanent team of 20+ in Poznań takes the work from positioning to the website, the deck and the product, scoped to a milestone 4 to 16 weeks out.
If the problem is the first screen and the story, Validate, from $2,500, covers positioning, market research and a written recommendation. If the site needs rebuilding, Launch, from $9,500, covers positioning, brand identity and the website. Build, from $25,000, covers an MVP or demo. All packages are in the pricing section.
Or start smaller: send us your website address, and your deck if you have one, and within one working day you get first notes on where your story is unclear to buyers or investors. It is not an audit or a score, just an outside read.
FAQ
What is the most common website mistake of funded B2B startups? Missing or weak proof did the most damage; the most frequent visible problems were slogans, broken first clicks and mismatched numbers.
Does good design make up for missing proof? No. A defence-tech startup with one of the best-looking sites scored 4 of 10: no company details, no team, no proof.
Which startup websites did best? Zynt (9 of 10), then Tequipy, Viktor, Kuro, Zeit AI, xorlab and Adaptyv Bio (8 of 10 each).
How can I audit my own site in an hour? Run the 60-minute self-audit above with three people, then fix the lowest-scoring dimension with the biggest gap first.
Should a B2B startup show pricing? Show a price, a range or a clear process. In long-sales segments, no public price is normal, and proof and trust weigh more.
How did you choose the 30 startups? Newest first from MamStartup and EU-Startups, pre-seed to Series A, 15 from Poland and 15 from DACH, never picked or skipped because of the website.
