Tonic.ai Synthetic Data Platform

Tonic.ai was founded in 2018 and is headquartered at 548 Market St, San Francisco, United States. Its stated mission is to unblock innovation with usable data by automating data synthesis for privacy and developer productivity. The About page lists a seed round, an 8 million USD Series A (2020) and a 35 million USD Series B (2021).

The product line has three parts: Tonic Structural de-identifies, subsets and synthesizes structured data; Tonic Textual redacts and synthesizes unstructured text and files; Tonic Fabricate generates synthetic relational data and mock APIs from scratch. In 2025-11 the company launched the Fabricate Data Agent, which generates datasets from a chat request or a schema.

• Tonic Structural: De-identify, subset and synthesize structured and semi-structured data.
• Tonic Textual: Detect, redact and synthesize PII in free text and files.
• Tonic Fabricate: Generate relational data, free text and mock APIs from scratch.
• Fabricate Data Agent: Chat-driven dataset generation exported as SQL, JSON, PDF and other formats.

A Vietnamese fintech can build staging databases from de-identified production data. An outsourcing firm can generate test data for foreign clients under NDA limits. A health startup can redact clinical notes before LLM use.

Gives developers realistic test data without production PII. Supports HIPAA, PCI, GDPR and SOC 2 use cases, with a security portal. Free entry points exist for Fabricate and Textual. Case studies report outcomes such as reducing an 8 PB subset to 1 GB (eBay, company-reported).

Demand is rising for safe test data and for training or evaluation data for AI when production data is restricted. Vietnamese software teams, fintechs and outsourcers serving regulated clients increasingly need de-identified datasets for development.
