What is Syntho?
Syntho produces synthetic test data for software development, testing and analytics, combining AI-generated data, rule-based generation and masking so companies can work with production-like data without exposing real records.
The Syntho Engine connects to existing databases with ready-made connectors and offers three methods: masking of sensitive values, rule-based generation and AI-generated synthetic data. A sensitivity scanner identifies protected fields, consistent mapping keeps relationships intact, and quality reports and upsampling support analytics use. The platform is deployed inside the customer's environment and can be automated through a REST API. Syntho is based in Amsterdam and names Philips, KPN and Nederlandse Spoorwegen as customers. Since June 2026 it also owns the MOSTLY AI brand, which continues as MOSTLY AI powered by Syntho.
Syntho AI features and use cases
- Generates realistic test dataAI models learn the patterns of production data and create synthetic records for test and development environments. Developers test with realistic data while real customer records stay in production.
- Finds sensitive columns automaticallyThe sensitivity scanner flags columns with personal or confidential data before generation starts. Data teams spend less time mapping which fields need protection.
- Checks synthetic data qualityQuality reports compare distributions and relationships of synthetic and original data. Analysts can judge whether the synthetic set is reliable enough for their models.
What sets Syntho apart
- Fixed feature-based license without per-generation or consumption fees.
- Runs inside the customer's own environment, so source data does not leave it.
