Customers who already use synthetic data

MOSTLY AI's synthetic data generator is trusted by major industry players across different sectors

Why is production and mock data not sufficient for testing anymore?

Beware of legacy data anonymization and generation techniques as they destroy the utility of data, kill your team’s efficiency, and endanger data privacy. Be smart and generate smarter synthetic data for speed, velocity, flexibility and cost-reduction.
Production data
Should not be used without proper anonymization
It‘s almost impossible to properly anonymize
Lacks outliers needed for negative testing
Too big and cumbersome to manage
Too small for stress tests
Rule-based mock data
70% of all test data is still created manually
Impossible to recreate all relevant business rules
Needs expert domain knowledge regarding the data
Not easy to maintain referential integrity
No correlations, no meaningful data

Production data needs proper anonymization and proper anonymization of production data is near-impossible. Behavioral data especially.

Rule-based mock data is hard to create and mock data requires expert knowledge of the data. Mock data has no correlations and referential integrity is hard to maintain.

With MOSTLY AI’s platform you can automate data anonymzation without any expertise in the data that you want to synthesize. You get high-quality test data with preserved referential integrity in minutes.
Generative AI mimics data so well that you can end up with a 1:1-like connection to your original data. The important underlying concept of synthetic data is that there are no 1:1 relationships between the original and the synthetic data. The real data is only used as learning material during the synthesization process. Only generalizable patterns, distributions or correlations are learned. MOSTLY AI’s platform generates synthetic data from scratch based on these patterns. There is no 1-to-1 link between original and synthetic data. Because of this missing 1-to-1 link, there is no direct attack surface for re-identifying sensitive information.

However, it is essential to point out that not all synthetic data is created equal. There are open source solutions out there without additional privacy mechanisms in place that can leak privacy. The process of synthesization does not guarantee privacy in itself. One of the possible issues is outliers or extreme values that can easily be re-identified.

MOSTLY AI’s platform uses different mechanisms to safeguard against privacy and re-identification risks. The first mechanism makes sure that our deep learning algorithm will not overfit the original data. The second mechanism is built-in privacy protections on all levels. We automatically disable all categories used by a few sets of individuals and protect extreme values in other data types as there could be a privacy risk. The third mechanism is the quality assurance report after generation. We evaluate the model and each batch of generated synthetic data with strict privacy metrics to detect any and all privacy risks.

Yes, MOSTLY AI’s platform can synthesize entire databases. You can have different tables and multiple connections between tables. MOSTLY AI supports numerous tables, and it can synthesize complete data sets.

The difference is in the basic approach. MOSTLY AI generates an entirely new data set that leaves no room for re-identification. The problem with data masking is that there is still a risk of re-identification. There is no good tradeoff between data masking and data utility. The approach we use is more secure, and it also opens the door to what we call programmable synthetic data. You can instruct the generative AI to generate data as you want.

We believe that synthetic data is not just about privacy. We believe that generative AI can improve businesses by unlocking the value in data for the problems that companies are trying to solve. For that reason, our next step is to work on programmable data.

We have both. We have a UI to test and validate everything from the customers' perspective. And you can orchestrate synthesization jobs through MOSTLY AI’s APIs.

Many customers are generating data to train and improve their ML and AI models. Generative AI-powered synthetic data can provide different advantages to AI/ML models, improve their performance and preserve the privacy of the original data.

There is no golden rule for that. It depends on the patterns, hidden business rules, and what you try to replicate. If you want to do text synthesization, generative AI will need more samples than categorical data. You can start with as little as 5000 rows, but you can leverage as much data as you want to upload. There is no limit. You can also get synthetic data from just a sample from your production data.

From a quality perspective, synthetic data looks real. MOSTLY AI’s platform provides a detailed QA report from a quality assurance perspective. We check the adherence of the synthetic data to the original data in terms of data distribution.

And the quality is not limited to the distribution adherence of single columns - what we call the univariate distribution. Our generative AI model can ensure a high quality of any column combination. Bi-variate, tri-variate, and so on.
