Denver, CO – November 2, 2021 – Crest Rock Partners is excited to announce that CloudNine, a leading electronic discovery (“eDiscovery”) software suite for legal professionals, has acquired ESI Analyst, the leader in forensic discovery software for emerging file types. The acquisition of ESI Analyst brings new analytical capabilities to CloudNine’s platform and enhances their customers’ experience navigating the evolving, complex data environment.

ESI Analyst processes and analyzes existing and modern file types such as mobile, chat, social media, text, computer activity, financial data, and more. Taking a unique approach to metadata, ESI Analyst allows for faster review by combining location, communication, and time data to create a coherent story through data visualization. The company was founded and led by Trent Livingston, who became CloudNine’s Chief Technology Officer subsequent to the transaction.

Mr. Livingston remarked, “We are absolutely thrilled to join the CloudNine family. Modern discovery is more than documents. It’s about telling the story. ESI Analyst’s leading standard for modern data combined with CloudNine’s longstanding and robust suite of discovery tools delivers a defensible, vigorous, unified platform to investigate, review and analyze both modern and traditional data. CloudNine’s large and sophisticated customer base will benefit immediately with the support of mobile, chat, social, and other modern data.”

“CloudNine’s customers continue to voice their need for a single platform to defensibly process, analyze, review, and produce both modern and traditional data. With the inclusion of ESI Analyst’s technology, we are very excited to now provide these important capabilities to the market”, said Georges Sabongui, CEO of CloudNine. “Law firms, legal service providers, corporate legal departments, law enforcement, and government agencies can leverage the platform in the cloud, on-premise, or as a hybrid to reduce costs, optimize cost recovery, and mitigate risk,” added Steve Vranas, CloudNine’s SVP of Sales & Strategy.
Crest Rock completed its investment in CloudNine in June 2021. Since then, the business has been investing in additional headcount across all departments in the organization and is accelerating product development initiatives to solve customer challenges across the EDRM lifecycle.
