Case Study: Exigent achieves 40% cost reduction and completes 14 TB/9M‑document review in six weeks with DISCO

Exigent and DISCO drive 40% cost reduction for Leighton Asia, a leading international construction company

Exigent, a global alternative legal services provider, was engaged by Leighton Asia to respond to a government inquiry that produced 14 TB of data (about 9 million documents) with a strict six-week deadline. To manage the volume, speed and multi-continent review, Exigent selected DISCO’s cloud-native eDiscovery platform, using DISCO’s high‑speed uploader and DISCO AI for review and prioritization.

DISCO employed AWS‑accelerated uploads and parallel processing to ingest data at up to ~3.1 TB/day (peaking at 6.2 TB in under 36 hours), enabling reviewers across four continents to begin work immediately; DISCO AI and ECA-driven predictive tagging reduced the set from 9 million documents to 1.2 million and then to 330,000 prioritized files. The DISCO solution let Exigent meet the six‑week deadline, deliver the review globally, and achieve a reported 40% cost reduction for Leighton Asia.
