Buying is subjective.Your marketplace should be too.
Sealabid is a sealed-bid marketplace. Buyers submit private offers in envelopes. Sellers only see how many envelopes exist — not the amounts — until the listing ends. Then, within 2 hours, the seller opens them and chooses who to sell to based on price and profile — or decides there's no sale.
Everyone must register and add a card before bidding or selling. Money is only taken when a seller accepts an offer.

How Sealabid fits you
Create a profile that actually matters
Sign up, verify your email, complete your profile (individual / business / charity), and add a short story. Sellers use this when choosing.
Submit what the item is worth to you
Place a sealed bid. You see the envelope count, not the amounts. You’re never publicly “outbid” — you just submit your true maximum.
List your item and choose your winner
Upload photos, write an honest description, set a private target, and choose 7, 14 or 21 days. When it ends, you have 2 hours to open envelopes and decide — or mark no sale.
Why “Buying is subjective” actually matters
Most marketplaces reward the highest visible bid or fastest click. Sealabid accepts that value is personal — and sellers may care who the item goes to.
Sealed, not public
Profiles carry weight
Seller keeps final say
