Helping businesses unlock the potential in their data.

Hazy is the most advanced and experienced synthetic data company. We accelerate innovation while increasing privacy at some of the world’s leading financial institutions. And we have fun and (sometimes) wear purple doing it.

We were founded in early 2017 by Harry Keen (CEO), James Arthur (CTO emeritus) and Dr. Luke Robinson (CSO). With one foot in big business and the other in academia, Hazy stands on the belief that privacy by design should not slow down innovation.

Originally a UCL AI spin out, London-based Hazy was initially incubated by Post Urban Ventures and CyLon cybersecurity accelerator. Our startup began trying to fix the flaws of traditional data redaction and then data anonymisation. We soon discovered anonymised data will always pose a risk to re-identification.

We looked at the opportunity in applying machine learning to synthetic data, which starts with the basis that with no real data there is no real risk. We pivoted our focus completely to AI-generated smart synthetic data and have worked to make it both differentially private and statistically representative. We quickly discovered that the organisations that would most benefit from smart synthetic data are highly regulated large enterprises with legacy architecture.

Hazy offsite brainstorming

Over the years Hazy has attracted a team of the best data scientists and engineers in synthetic data and privacy, and with roots in regulated industries. Together we are incorporating cutting-edge research as soon as it’s published into production.

We’ve also grown our leadership team including our CTO Tim Budden and our COO Andrew Keen, who each bring more than 20 years’ experience in the enterprise software space.

Together we are all laying the groundwork for an information economy that allows you to work with people’s data while always respecting their privacy.

In 2018, Hazy won the $1 million Microsoft Innovate AI prize for the best AI startup in Europe.

In 2019, Hazy won a number of awards including the Grand Prix at the prestigious Société Générale Banking CyberSecurity Innovation Awards and the CogX Award for Best Innovation In Data Protection And Privacy.

Hazy now works with some of the world’s leading companies, including Accenture, BMW Group and Nationwide, the world’s largest building society. The company is backed by investors including Microsoft (M12), Notion, Amadeus, Albion and Pentland.
