Merlin may be new,
but the team is not. . .

We’ve been building search, analytics and review software since the nineties.

About Merlin

Merlin Digital Magic, Inc. is a cloud technology company, developing AI-powered search, analytics and review software. The company was formed in March of 2019 by a legal technology pioneer and his longstanding  team of  designers, developers and operations professionals.

We got our start in the mid-1990s as part of a national law firm. It was there that our founder, John Tredennick, famously built litigation and compliance systems for the firm and then the firm’s clients. Over the years, we were featured in videos by Adobe and Microsoft, were written about in legal magazines, won a number of innovation awards and, ultimately, were inducted into the Smithsonian Institute for our groundbreaking work developing litigation workflow software.

In 2000, the Tredennick team spun out of the law firm to form Catalyst Repository Systems, a pioneering e-discovery and compliance technology company. Over the next two decades, Catalyst grew to more than 160 people and five data centers, hosting software for many of the largest companies and law firms in the world. 

In early 2019, we sold Catalyst to a large public technology company. Not ready to retire, John Tredennick founded Merlin, bringing aboard a number of his previous team members as the company grew. We have the luxury of starting from scratch, building all new software using the latest and greatest technologies available. And an incredible chance to deliver it securely over the AWS cloud.  

We are passionate about the future of search.  And the chance to bring digital magic to our new clients.

From our Founder

Merlin is the  third act of my professional life. I spent the first 20 years as a trial lawyer and partner in a national law firm. I then founded and spent another 20 years running Catalyst Repository Systems. During that time, we built the best and most powerful ediscovery platform in the world along with dozens of custom compliance systems for some of the largest companies and law firms in the world. 

At Merlin we have the chance to start over, integrating the newest artificial intelligence algorithms, the latest open source technologies with our own digital magic. Our mission is to help people find the information they need in large document populationsquickly and easilywithout having to master complex search syntax. 

We are passionate about building the next generation of AI-powered search, review and compliance software and  about delivering our systems securely from the cloud. We are passionate about delivering the future of search.
