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, use it well, and complete the deal smoothly.
That’s why we use sealed envelopes. Buyers place private offers. Sellers only see the envelope count until the listing ends. Then the seller opens the envelopes and chooses based on price and profile — or decides there’s no sale.
Everyone must register and add a payment method before bidding or selling. Money is only taken if a seller accepts an offer.
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).
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.
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.
