A marketplace where the right buyer can win.
Sealabid exists because buying is subjective. Sometimes the “best” buyer isn’t the fastest click or the loudest bid — it’s the person, charity, or business who will genuinely value the item, look after it, and complete the deal smoothly.
Two lanes
Sealabid runs two clearly separated sections: Public Sealed Bids (open marketplace) and Premium Retail Storefronts (approved retailers with branded shop pages).
Either way: offers are private, sellers choose the outcome, and sold prices aren’t shown publicly.
Buyers place sealed offers (“envelopes”). Sellers only see the envelope count until the listing ends. Then the seller opens envelopes and chooses based on price and profile — or marks no sale.
You need an account to bid or sell. Money is only taken if a seller accepts an offer (secure payment flow).
What “subjective” means here
It’s not a loophole.
It’s a design choice: sellers can pick the buyer they trust to complete the deal, not just the biggest number on the page.
Sellers can prioritise
- ✓ reliability + fast completion
- ✓ a charity/cause they want to support
- ✓ a collector who will look after the item
Sellers must decide
Once the listing ends, the seller has 2 hours to open envelopes and choose a winner (or mark no sale).
Privacy, by default
Offers are private. Outcomes are private. If a deal is accepted, the next steps are handled between buyer and seller — not as public entertainment.
Two sections, clearly separated
Public Sealed Bids
Open marketplace, sealed offers.
Anyone can browse. Buyers submit private offers (“sealed envelopes”). Sellers choose the outcome at the end — highest isn’t mandatory.
- ✓ No bidding wars, no public outbidding
- ✓ Sellers only see envelope count until the end
- ✓ Seller can accept or mark “no sale”
Premium Retail Storefronts
Approved retailers. Branded shop pages. Full discretion.
Built for premium retailers who want brand control and confidentiality. Display curated goods, receive sealed offers, and only engage with the buyer once you choose to proceed.
- ✓ Your branding: logo, banner, policies
- ✓ Accept or reject offers — always your call
- ✓ Discreet outcomes: no public sold prices
Premium storefronts are approved and curated to protect brand and buyer confidence.
Public listings are open to everyone. Premium storefronts are approved and curated.
Our story in one sentence
Most marketplaces train people to chase the moving number. Sealabid does the opposite: it encourages one honest offer — and lets a human choose the outcome.
It’s calmer for buyers, better control for sellers, and it opens the door for purpose to matter: charities, community groups, small businesses, collectors, makers — anyone with a real reason to buy can be considered.

For premium retailers
Brand control + confidentiality. A calmer way to sell premium goods.
Sealabid is designed for retailers who don’t want public price pressure or bargain-hunting noise. You can present curated inventory, receive sealed offers, accept or reject with full discretion, and keep accepted deal details between you and the buyer.
Control
Accept the buyer you want — or decline all offers.
Confidential
Offers are private. Outcomes stay private.
Premium presentation
A branded storefront built for curated goods.
Premium storefronts are approved. This keeps the retail section curated and protects buyer confidence.
How it works
Create a profile that builds trust
Choose individual, business, or charity. Add a short story. When offers are close, the seller may use your profile to decide.
Place one sealed offer (your real maximum)
No public outbidding, no sniping. You submit what the item is worth to you. Sellers only see envelope count until the end.
Seller opens envelopes and chooses
At the deadline, envelopes lock. The seller opens them and chooses based on price + profile. Seller has 2 hours to decide — or mark no sale.

A quick rule that keeps everyone safer
Keep contact details on-platform. That means no phone numbers, emails, or links in public stories or messages. It reduces scams, keeps privacy intact, and makes disputes easier to handle.
