How Lighthouse pricing works

Lighthouse publishes a price list called Pricing for Additional Lighthouse Services, titled 2023 rates. It is part of the Master Spectra Subscription Agreement and applies to any Lighthouse service unless the order form states otherwise.

Hosting: online hosting is $12 per GB a month, nearline hosting $7.20 and offline hosting $3.60, and Relativity users are $89 per user a month. Hosting is billed monthly and is not prorated. Forensics: collection is $295 an hour, forensic analysis $375 an hour, senior forensic analysis $475 an hour and expert testimony $550 an hour. Processing: OCR is $0.02 a page, and ChatSmart chat processing is $5,000 a matter. Review tools are charged per document, with EmailSmart at $0.025 and ReviewSmart at $0.05.

Machine translation runs from $0.94 a file for the first 40,000 files down to $0.38 a file over 100,000. Audio and video transcription has a $625 project setup fee.

The $12 figure is the main recurring rate on the list, not a plan price. No price is published for the Spectra subscription or for LighthouseIQ.

Implementation: No general setup fee is listed. Audio and video transcription projects carry a $625 setup fee. Spectra's agreement gives a free Tier 1 support level and a paid Tier 2 expert level.

Note: Under Spectra's agreement, fees are set in an order form, the subscription renews automatically each year, and rates can rise on 90 days' notice. Notice is needed to stop hosting.
