About Mostly AI

MOSTLY AI is a technology company specializing in the generation of AI-powered synthetic data for enterprises. Founded in 2017 in Vienna, Austria, by data scientists Michael Platzer, Klaudius Kalcher, and Roland Boubela, the company emerged from the founders' experience with the limitations of traditional data anonymization, a challenge amplified by the introduction of GDPR in Europe. They pioneered the concept of using generative AI to create business-ready synthetic data for structured, tabular datasets, drawing inspiration from advancements in synthetic imagery.

Read full description

The company has raised a total of $31.1 million over five funding rounds. A significant milestone was its $25 million Series B funding round in January 2022, led by Molten Ventures with participation from Earlybird, 42CAP, and Citi Ventures. This funding was aimed at accelerating its growth in Europe and the United States and expanding its team.

The core of MOSTLY AI's offering is its Data Intelligence Platform, which allows organizations to generate high-fidelity, privacy-compliant synthetic data. This technology creates statistically representative datasets that mirror real data's patterns and correlations without containing any original personal information, thereby eliminating re-identification risks. The platform's features include a user-friendly interface, support for time-series and multi-table data structures, and a proprietary algorithm to ensure accuracy. More recently, the platform has incorporated the MOSTLY AI Assistant, a conversational AI that allows users to analyze data and derive insights using natural language. The company also offers an open-source Synthetic Data SDK for Python, enabling users to create synthetic data within their own environments.

MOSTLY AI operates on a B2B model, primarily serving enterprises in highly regulated industries such as banking, insurance, and healthcare. Its business model includes a freemium offering, allowing users to experiment with the technology, and paid enterprise plans that provide advanced features and scalability. By providing as-good-as-real, yet fully anonymous data, MOSTLY AI enables clients to accelerate AI/ML development, enhance software testing, and facilitate secure data sharing across teams and with external partners, while complying with privacy regulations like GDPR and CCPA. The company states its technology can reduce time-to-data by 90% and save large companies over $10 million annually.
