Synthetic data engine

Production-grade data, zero production risk.

CrossRow generates synthetic datasets that behave like the real thing: ledgers reconcile, foreign keys resolve, state machines walk legal paths, distributions hold. Not a single byte of customer data leaves your perimeter.

Not screenshots. This data is being generated now. Watch the invariants: cities match countries and currencies, running balances foot to the penny, statuses only move along legal transitions. CrossRow verifies every rule after generation and puts the results in your quality report.

01 / What most generators fake, CrossRow enforces

Realism isn’t a look. It’s a set of invariants.

Random values in the right format fool nobody, least of all your integration tests. CrossRow generates each row in the context of every other row, then runs an independent verification pass and scores the output.

/01
Ledgers that reconcile
Running balances foot to their targets, ordered by transaction time. Debits, credits, and opening balances are consistent across millions of rows: balance = prev + amount holds on every row, and the closing balance lands where the plan says it should.
/02
State machines, not status soup
Order lifecycles, claim workflows, patient journeys: statuses only move along legal transitions with realistic dwell times. A shipment is never delivered before it’s picked_up.
/03
Relational integrity, all the way down
Foreign keys resolve across tables and batches, including the hard case: self-referential hierarchies like manager_id and parent_category_id, with realistic org depth and null rates.
/04
Geography that agrees with itself
Mumbai sits in India, bills in rupees, and its customers have locale-appropriate names. City, state, country, currency, and person names are correlated per-row, never independently sampled.
/05
Formulas & distributions that hold
Derived columns compute exactly (tax = gross × 0.22, date offsets, string expressions). Numeric columns follow the distribution you asked for (lognormal, Benford, seasonal), and the quality report proves it.
/06
Verified, then scored
Every generation ends with an independent quality pass: FK validation, formula accuracy, distribution checks, cross-row rule verification. You get a scored report, not a shrug.
02 / How it works

Describe the data you need. Get data that needs no apology.

STEP 01

Describe or import

Bring a schema, pick an industry template, or describe the dataset in plain English. CrossRow drafts the full generation plan.

STEP 02

Plan & harden

Semantic analysis infers types, correlations, and constraints. Automatic plan review catches contradictions before a single row is generated.

STEP 03

Generate at scale

Streaming generation with live progress: from a 50-row sample to hundreds of millions of rows, straight to S3, a database, or files.

STEP 04

Verify & ship

An independent validator re-checks every invariant and scores the run. Wire the output into CI, demos, load tests, or ML pipelines.

03 / Battle-tested across industries

Your next environment doesn’t need production data.
