Which vendors generate tabular and text data?
These vendors learn from database tables (and, for Tonic.ai, text and files) and generate new rows for testing, analytics and model training.
| Vendor | What it makes | Data types | Delivery | Published price | Ownership change |
|---|---|---|---|---|---|
| Tonic.ai | Three products: Structural (databases and other structured data), Textual (free text and files) and Fabricate (new data from a schema or prompt) | Tables and text | Software platform | Not published | Bought Fabricate (built by Mockaroo) on 22 Apr 2025 |
| Syntho (and MOSTLY AI, powered by Syntho) | Synthetic tabular data platform based in Amsterdam; now also runs the MOSTLY AI brand | Tabular | Software platform | Not published | Syntho bought the MOSTLY AI trademark and related assets on 9 Jun 2026; the brand continues as "MOSTLY AI, powered by Syntho" |
| Aindo | Synthetic data platform from Trieste, Italy, aimed at regulated sectors | Tabular | Software platform | Not published | None found |
| K2view | Data management vendor whose synthetic data tool mixes AI generation, business rules, cloning and masking | Tabular | Software platform | No prices on the page; offers a "Start Free" option | None found |
| SAS Data Maker | SAS's synthetic data product, which took in Hazy's software | Tabular | Software platform | Not published | SAS bought Hazy's principal software assets on 12 Nov 2024 and folded them into SAS Data Maker |
Some vendors in this table may pay an introduction fee when a team we put in touch signs with them. Whether a vendor pays has no effect on the list, its order or our notes.

Which vendors generate images and simulated scenes?
These render labeled imagery and sensor data from 3D scenes, mostly for perception models in vehicles, robots and remote sensing.
| Vendor | What it makes | Data types | Delivery | Published price |

| Parallel Domain | Synthetic data and simulation for training and testing perception systems in autonomous vehicles and robotics (PD Platform, PD Forma, PD Sim) | Images, video, 3D | Software platform | Not published |

Our own check
Syntho buys the MOSTLY AI trademark and related assets; the brand carries on as "MOSTLY AI, powered by Syntho". What became of the original company was not stated.
KPMG agrees to buy YData Labs' IP and technology assets. We no longer list YData as an independent vendor.
Tonic.ai buys Fabricate, the schema and prompt generator built by Mockaroo.
TechCrunch reports that NVIDIA has acquired Gretel. From here on Gretel counts as part of NVIDIA on this site.
SAS buys Hazy's principal software assets and folds them into SAS Data Maker.
How this list is put together
This site is independent. It is not affiliated with, sponsored by or endorsed by any company named on it, and it has not tested or audited any of their products: everything here comes from what each company publishes.
A vendor is listed when its own site confirmed it was operating on the day we checked. A price, certification or ownership change appears only when the vendor's page or a dated report says it; anything else reads "Not published". If a vendor tells us a fact is out of date, we check the page again and log the change above.

Questions about the vendor list
How many synthetic data vendors are on this list?
Seven: five for tabular and text data (Tonic.ai, Syntho with MOSTLY AI, Aindo, K2view, SAS Data Maker) and two for images and simulation (Rendered.ai, Parallel Domain). We list a vendor only if its own pages confirmed it was operating when we checked on 7 Nov 2026.
Why is Gretel not on the list?
TechCrunch reported on 19 Mar 2025 that NVIDIA had acquired Gretel. We treat it as part of NVIDIA rather than an independent vendor you can contract with.
Are MOSTLY AI and Syntho the same company now?
Syntho announced on 9 Jun 2026 that it had bought the MOSTLY AI trademark and related assets, and the brand continues as "MOSTLY AI, powered by Syntho". The announcement did not say what became of the original company, so we list them as one vendor.
Is this list a ranking?
No. Vendors are grouped by the data they generate, not scored. We have not tested any product; every fact comes from the vendor's own published pages or a dated news report.
How often is the list checked?
Each vendor page was read on 7 Nov 2026. The changelog on this page records every change we find in ownership, prices or published terms, with its date.
