For healthcare, insurance & finance data

Sell data you can’t hand over.

Patient records, claims and transactions can’t go to a broker as raw rows. Here they don’t have to: synthetic buyers get newly generated rows, never your records.

  1. 01

    List with a sample

    Upload up to 1,000 rows. Buyers see statistics and a synthetic preview, not your sample rows.

  2. 02

    The full file only on an order

    When a buyer orders, you have 7 days to upload the rest. No order, no upload.

  3. 03

    Generated on our servers

    For synthetic orders our engine learns from your full file and delivers new rows with a measured fidelity and privacy report. Rows that copy a real record are re-drawn.

  4. 04

    Every step on record

    File hashes, inspection results, the license the buyer accepted and an audit log for each delivery. Payment is held at order and released to you on delivery.

You choose whether to offer original rows at all.

Synthetic Twins
Private clinical data, safely copied
Three ways to get data

Buy it. Train on it. Or twin it.

Sellers choose which access methods they offer. You choose how close you need to get to the raw records.

01 · Download License

Buy & download

Download the full verified dataset with a clear license detailing AI training and commercial rights. Keep it permanently in your S3/GCS buckets.

job.py
weights.bin
02 · Compute-to-data

Train in place

Send your containerized training job into the seller's secure enclave. It trains directly beside the records, and returns model weights — never the raw customer rows.

03 · Privacy Preserving

Get a synthetic twin

For clinical or private financial data, download a mathematically validated synthetic copy with identical statistical distributions, zero PII, and full privacy guarantees.

Trust & Licensing

Every stall is inspected before it opens.

ByteBazaar validation agents inspect every dataset before listing and continuously audit on each version update.

  • Schema & Completeness Columns match published docs. Missing values are precisely measured, never hidden.
  • Privacy & PII Scanning Comprehensive regex, NER, and biometric checks eliminate direct personal identifiers.
  • Provenance Verification Sellers submit legal documentation proving original ownership and sublicensing rights.
