We are familiar with Antitrust Division and Bureau of Competition staff and DOJ and FTC production formats. We will readily meet and discuss technical issues with staff when such issues arise.
We offer a Technology Assisted Review (TAR) solution that is ideally suited to the formal and informal predictive coding guidance from regulators.
HaystackID’s size, stability, and client-centered approach allow us to offer pricing models that are transparent, predictable, customizable, and exceptionally cost-effective.

Merger Control and Substantial Compliance

HaystackID’s Antitrust Investigation Services team understands that merger control is not the same as fast-moving litigation. We know what substantial compliance means, and we understand the far-reaching effects that a missed production can have – not just on substantial compliance in the U.S. but on the proposed transaction itself. We know what it means if we identify a previously unproduced Item 4(c) or 4(d) document early in processing, and perhaps most importantly we know what it means to reach substantial compliance quickly and cost-effectively.

Antitrust Insight from HaystackID Experts

Precision eDiscovery for Complex Antitrust Agency Investigations

During the COVID-constrained summer of 2020, HaystackID supported a leading global finance platform company and its internationally recognized outside counsel in responding to a Department of Justice (DOJ) Second Request based on a proposed acquisition of a highly regulated company. This Second Request resulted in the need to collect and evaluate 18TB of data, including significant stores of Slack messages and files, from both onsite and remote locations from more than 17 types of data stores. Within a period of 106 days, HaystackID completed approximately 300 collections, developed custom tools and processes, including innovative Slack-specific communications heat maps, predictive coding processes, and private message privilege identification, to enable a compliant response of a complex investigation request, ultimately enabling completion of the proposed acquisition.

Antitrust Agency Request Support

A proven provider of eDiscovery support for FTC and DOJ Second Requests, HaystackID was especially active during a four-month period of mid-2019 when it successfully supported six separate Second Requests. These six requests required both antitrust request process experience and cannabis industry expertise in order to meet and exceed reporting requirements for the time-sensitive, comprehensive information and documentation requests.
