Synthetic Data for ML Teams

Generate synthetic training data that keeps real records private

Synthpylon produces statistically faithful datasets that match your production schema, so teams can train and share models without exposing personal information.

Privacy law didn't stall your data. It exposed the gap

  • Production databases off-limits for dev and test environments
  • HIPAA and GDPR block sharing patient or customer records with ML contractors
  • Minority classes too rare to train classifiers reliably
  • Analyst teams can't run aggregate queries on personally identifiable data

These aren't edge cases. They stop entire ML pipelines. We built Synthpylon because every workaround we tried (masking, sampling, access controls) still left the real data at risk, or left the model underfed.

The answer isn't a stricter access policy. It's data that was never real to begin with.

From schema to synthetic dataset in minutes

01

Connect your schema

Point Synthpylon at your database schema or upload a sample CSV (we never store raw records). We learn the statistical fingerprint: distributions, correlations, cardinality.

02

Set your generation rules

Choose row count, class balance targets, rare-event oversampling, and any column constraints. Your domain, your rules.

03

Export and ship

Download as CSV, Parquet, or JSON. Or stream directly into your training pipeline via our API. The output dataset contains zero real records.

What makes synthetic data usable

Schema-preserving generation

Output columns match your input schema exactly: same types, same referential constraints. Foreign keys stay coherent. No downstream pipeline breakage. Connect via JDBC, DDL upload, or CSV sample.

Statistical fidelity scoring

Every dataset ships with a fidelity report: marginal distributions, pairwise correlations, and a downstream-model-accuracy delta vs. training on real data.

Privacy proof by design

No real records stored, no reversible transformations. Differential privacy budget configurable. Formal membership-inference attack resistance built in.

Rare-class amplification

Fraud transactions, rare diagnoses, edge-case sensor readings. Generate as many minority-class rows as your model needs, without inventing unrealistic examples.

What ML teams say

We had 800 labeled fraud samples in production. Synthpylon got us to 12,000 synthetic rows with matching distribution. Our recall on the minority class jumped from 54% to 81%.

ML lead at a payments platform

Our HIPAA data couldn't leave the hospital firewall. With Synthpylon, our contractors train on synthetic EHR data outside. The research velocity doubled.

Data engineering lead at a regional health system
