We regularly work with substantial volumes of real-time and historical data, with individual tables comprising hundreds of billions of records.

Our in-house massively parallel processing capabilities and a team of programming specialists ensure that we can conduct large-scale data analytics efficiently and effectively. Our specialized expertise and secure computing facilities allow us to maintain, update, and manage the public and private data used to support expert consulting and testimony.

These resources allow us to ensure ongoing data integrity and navigate the evolving data needs specific to the numerous stages over the potentially long-range horizon of litigation, regulatory, and investigation matters. Our cutting-edge information-retrieval and management tools minimize business disruption and create efficiencies for our clients.

Client Data Production

Clients frequently rely on us to compile large datasets from disparate sources and incompatible formats. We also manage outside vendors for data entry, extraction, and reconciliation to minimize the cost of construction.

We help counsel manage the discovery and data production process and work with clients to thoughtfully and efficiently extract information in anticipation of the analytical needs of subsequent phases of work as well as in response to direct requests from regulators or litigants.
