Cycling through all six. Tap any point to stop.

Measured on six things

Travellers rent out the empty space on their suitcase, and brands bid for it.

Growth

A real, specific problem with a concrete wedge: escrow-style payouts and automatic refunds if stickers never go on. But the marketplace is two-sided and currently has one traveller and two brands.

About this app

A suitcase spends its life in baggage claim, on trains, in hotel lobbies and in the background of other people's photographs. Nobody was selling that space. Adonboard is a marketplace for it. A traveller lists their case: its size, colour and shell, where it is going and how often they fly. They lay out sticker spots on a 3D model of the case, set an opening price for each, and publish. Brands bid. Every bid must double the one before it, so nobody nudges a spot by a euro and a contested spot finds its price quickly. A traveller can also offer spots at a fixed price, for whoever claims them first. When bidding closes the winners are charged, the traveller receives the logos, applies the stickers and photographs them on the real case. The brand approves that photo from their dashboard or by email, and approving releases the traveller's share. If the stickers never go on, the brand gets its money back automatically.

Key features

2Escrow-style payouts: brands approve a photo of the applied stickers before the traveller's share releases, with automatic refund if stickers never go on
33D suitcase configurator that draws the case from size, shell type and colour — no photos or scanner needed

Scout Review

Written by AI from measured evidence, scored out of 100.

Adonboard is a marketplace for advertising space on travellers' suitcases — brands bid on sticker spots, bids must double the previous one, and payouts release only after the brand approves a photo of the stickers actually applied. The escrow flow is the smartest part of the product and the clearest reason to pick it over just DMing a travel influencer. The marketing site is polished, fast on desktop, and security headers are nearly complete. The problems are the ones every two-sided marketplace has on day one: one traveller, two brands, no docs, no pricing page, and a mobile LCP of 4.0s. It's a well-built shell around an idea that needs liquidity to prove itself.

Measure by measure

Usability

The 4-step flow is clearly explained and listing is free, but no docs, help center or pricing page content was captured. Onboarding depth beyond the homepage pitch is unverified.

Design

Dark, modern marketing site with a live bid ticker and clean listing cards. The 3D suitcase concept is a genuine differentiator, but only the website was visible — the app UI itself was not captured.

Speed

Lighthouse mobile 86/100 with CLS 0 and TBT 18ms, desktop 97/100. The 4.0s mobile LCP is the weak spot on an otherwise lean page.

Security

11/12 security headers with HTTPS, HSTS, CSP and frame protection all enforced. SPF is missing and no SOC 2, ISO or pen-test claims were found, which is normal at this stage.

Accessibility

Lighthouse accessibility 97/100 with a single contrast failure. No a11y statement or WCAG mention found, and multi-language support is unverified beyond the country dropdown.

Growth

A real, specific problem with a concrete wedge: escrow-style payouts and automatic refunds if stickers never go on. But the marketplace is two-sided and currently has one traveller and two brands.

Improvement areas

No documentation, help center or pricing page content found — payouts, disputes and brand onboarding are unexplained
Mobile LCP of 4.0s drags the otherwise strong Lighthouse mobile score down to 86/100
Missing SPF record and no published security certifications despite handling payments between brands and travellers

Design & Usability

The marketing site is genuinely well-built: dark theme, live bid ticker, consistent listing cards, and a 3D suitcase concept that no competitor is doing. The 4-step flow (pick suitcase, choose layout, let brands bid, stick them on) is explained clearly and listing is free with a 10% commission on sale. What's missing is everything after the homepage — no docs, no help center, no pricing page content was captured, so how payouts, disputes or brand onboarding actually work is unverified. The design is ahead of the category for an early-stage marketplace; the usability depth is not yet demonstrated.

Speed & Security

Speed is a mixed bag: Lighthouse desktop 97/100 and mobile 86/100 with a perfect CLS of 0 and TBT of just 18ms, but mobile LCP sits at 4.0s, which is the one number dragging the mobile score down. On security, the header probe came back 11/12 — HTTPS enforced, HSTS, CSP, frame protection, X-Content-Type-Options, Referrer-Policy and Permissions-Policy all present. The single miss is SPF, which matters more than usual here because the product handles payments and brand communications. No SOC 2, ISO or pen-test claims were found, which is expected at this stage but worth watching as money starts moving through the platform.

Accessibility & Growth

Accessibility scores 97/100 on Lighthouse with one failing audit: insufficient colour contrast. That's a fixable bug, not a structural problem, but there's no accessibility statement or WCAG mention anywhere on the site, and multi-language support is unverified beyond a country dropdown. On growth, the idea is real and specific — suitcase surface area is genuinely unsold inventory, and the escrow mechanic (brand approves the photo, traveller gets paid, automatic refund if stickers never go on) is a concrete trust differentiator that generic ad marketplaces don't have. The honest limit is the two-sided cold start: the homepage currently shows one traveller and two brands, and most listing slots are placeholders. The wedge is good; the liquidity is the whole game.

Conclusion

If Adonboard can solve the cold start — get enough travellers listing enough trips that brands see real inventory — the escrow mechanic and the 3D suitcase configurator give it a defensible position that a generic ad marketplace can't easily copy. The 10% commission is fair, listing is free, and the automatic refund if stickers never go on removes the main reason a brand would hesitate. What it needs now is volume, documentation, and a contrast fix. The foundation is there; the question is whether the two-sided flywheel spins before the runway runs out.

Suggestions for improvement

Publish a real docs/help center covering payouts, disputes and brand onboarding — the homepage flow is clear but nothing after it is documented
Fix the mobile LCP (4.0s) — preload the hero assets and audit the 3D suitcase renderer's impact on first paint
Add an SPF record to complete the email security posture, especially with payments and brand comms running through the domain
Fix the colour contrast failure flagged by Lighthouse and add a short accessibility statement to the footer
