The short version

  • Each has a real cost: DISCO per-gigabyte pricing that is attractive on a 200 gigabyte matter becomes the dominant line item on multi-terabyte collections, and the only cost lever left is aggressive culling before upload.; iManage it manages documents and email but not matters, billing or accounting, so it is an addition to a practice management system rather than a replacement for one.
  • They diverge on capability: DISCO covers All-in per-gigabyte pricing, iManage covers iManage Work.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

DISCO

  • Per-gigabyte pricing that is attractive on a 200 gigabyte matter becomes the dominant line item on multi-terabyte collections, and the only cost lever left is aggressive culling before upload.
  • Hosting is cloud only in United States regions, so matters with European, United Kingdom or Australian data residency requirements are excluded outright.
  • Review analytics, scripting and the third-party application ecosystem remain deeper on Relativity, which matters for firms with established review workflows.
  • As a listed company reporting losses, it has been through leadership change including the founder departure in 2023, so multi-year roadmap commitments carry more risk than with a private vendor.
  • Complex productions and unusual data types still require professional services, so the promise of self-service holds mainly for mainstream email and document collections.

iManage

  • It manages documents and email but not matters, billing or accounting, so it is an addition to a practice management system rather than a replacement for one.
  • Administration requires specialist skills, and organisations without a dedicated document management administrator tend to run it badly configured.
  • Its value depends on fee earners filing email consistently, which is a behaviour change firms routinely fail to enforce.
  • Nothing about pricing is published and the surrounding modules are licensed separately, so the gap between the core product and a working configuration is discovered late.
  • The market-share figures it cites, such as 81 per cent of the Am Law 200, are vendor published and not independently audited.

Answered from the vendors’ own pages

DISCO: How is DISCO priced?

Per gigabyte of hosted data per month, all-in, with unlimited users. There is no published rate card, so it is quoted.

iManage: Does iManage replace practice management software?

No. It handles documents and email. Firms run it alongside a practice management and billing system such as Aderant or Elite 3E.

DISCO: Can data be hosted outside the United States?

Coverage is centred on United States cloud regions, so confirm residency before shortlisting for European or Australian matters.

iManage: Who owns iManage?

It has been independent since a management buyout from Hewlett-Packard completed in July 2015. Bain Capital Tech Opportunities made a minority growth investment in April 2023, with management retaining control.

DISCO: Is it cheaper than Relativity?

On small and mid-sized matters usually yes, because seats and analytics are included. On very large collections the volume charge often overtakes a negotiated Relativity arrangement.

iManage: Is iManage worth it for a small firm?

It is sold to small firms as well as large ones, but the licensing and administrative overhead usually outweighs the benefit over a well organised document store below roughly twenty fee earners.
