  • They diverge on capability: DISCO covers All-in per-gigabyte pricing, Harvey covers Legal research assistant.

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.

Harvey

  • There is no published pricing anywhere, and no self-service tier at all, so even qualifying for a quote requires an enterprise sales process most small and mid-size firms cannot justify starting.
  • 25-seat minimums put it structurally out of reach for solo, boutique and most mid-size firms regardless of interest.
  • Reported additional platform fees on top of the headline per-seat licence mean the effective total cost is materially higher than the quoted seat price alone suggests.
  • As a well-funded, fast-growing AI vendor, its product and pricing model are still evolving quickly, which is a real risk for a firm signing a multi-year enterprise contract now.
  • Being trained and marketed specifically for BigLaw workflows means smaller firms evaluating it are comparing themselves against a product that was not built or priced with them in mind.

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.

Harvey: Can a small firm buy Harvey?

In practice, no. There is no self-service tier, and reported 25-seat minimums and six-figure contract values put it out of reach for most small and mid-size firms.

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.

Harvey: How much does Harvey actually cost?

Nothing is published. Third-party reporting estimates $1,000-2,000 per seat per month and enterprise contracts from roughly $360,000 to over $1.5 million a year including platform fees.

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.

Harvey: Does Harvey replace Westlaw or LexisNexis?

No. It is an AI research, drafting and review layer, typically deployed alongside rather than instead of a primary legal research database.
