Any file type accepted. Drag and drop on the upload page. Our AI organizes it automatically. Usually takes under a minute.
Everything: spreadsheets, PDFs, Word docs, images, even photos of handwritten records. We convert and normalize it all.
You set a secret minimum you're willing to accept. If bidding doesn't reach that amount, the auction closes without a sale — and you can re-list for free.
Within 2 business days of a successful auction close. Direct to your bank account (Stripe) or PayPal.
DataVault takes 5% of successful sales. If your data sells for $1,000, you receive $950. There are no listing fees or monthly charges.
Your file is encrypted with AES-256 before it ever leaves your device. We never see your raw data. Only the winning buyer receives a decryption key.
For Buyers

Open English auction — you can see the current top bid and outbid it by at least $10 (or 5%, whichever is more). Bids are binding.
Only if your bid wins. We authorize your card when you bid but only charge if you win the auction.

If the top bid is below the seller's reserve, the auction closes without a sale. Your card is not charged.
