Syntho Engine

Syntho is a synthetic data company based in Amsterdam, the Netherlands, focused on helping organizations move synthetic data from pilots into production. The founding year is not stated on the pages reviewed. The company lists awards including a Philips Innovation Award and selection by NVIDIA as a leading generative AI scale-up.

Syntho Engine unifies three approaches: AI-generated synthetic data, synthetic data masking and rule-based synthetic data. It adds a sensitivity scanner, database connectors, a REST API, privacy audit reports, access control and foreign key management. It runs inside the customer's own environment. A platform update in 2025-10 added 150+ mock generators, virtual tables for database views and workspace modes.

• Synthetic data masking: Sensitivity scanner, mock data and consistent mapping.
• Rule-based generation: Formula-based and pattern-based generators plus subsetting.
• AI-generated data: Quality assurance report, upsampling and an AI assistant.
• Connectors and API: Source and target database connectors and a REST API.
• Privacy audit report: Documents privacy checks on generated data.
• Team controls: Access control, collaboration and foreign key management.

A Vietnamese bank can create masked test databases for core banking releases. A software vendor can generate demo datasets for sales. A hospital group can share synthetic patient tables with research partners.

Produces realistic test and demo data without exposing production records. Combines several generation methods in one run. Deployment inside the customer's environment keeps data under local control. The 2025 update claims much faster setup for large databases (company claim).

Test data management and AI training increasingly rely on synthetic data as privacy rules restrict use of production data. Vietnamese banks, insurers and software vendors adopting cloud and AI face the same constraint under personal data protection requirements.
