Where each one falls short

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

Didomi

Pricing is based on monthly unique visitors and is not published, so a large publisher cannot estimate cost before entering a sales process, and traffic spikes translate directly into billing surprises.
Consent banners depress measurable traffic by design, and Didomi cannot prevent that, so publishers moving from a non-compliant banner should expect an immediate drop in tracked users and attributable conversions.
Certification is a moving target: Google and IAB update requirements periodically and each version change forces integration work on your side, not only on the vendor's.
Connected TV consent collection depends on the app platform and remote control interface, and implementations are considerably more involved than a web banner, often requiring per-platform development.
The wider privacy suite beyond consent is thinner than dedicated privacy platforms, so an organisation needing data subject rights automation and data mapping usually buys a second vendor anyway.

Luminance

No independent evaluation of its accuracy has been published, and it did not take part in the Vals Legal AI Report, so buyers have only vendor-produced evidence to work from.
The one named accuracy benchmark, ContractIQ Bench, was built, run and scored by Luminance on a dataset it has not released, against comparison models it does not name.
Value scales with document volume, so an organisation reviewing tens rather than thousands of contracts will not recover the licence cost.
Output still requires qualified review, so it reduces reading time rather than removing the lawyer, and staffing plans that assume otherwise fail.
Pricing is not published, so cost per matter cannot be modelled until after a sales process and a proof of concept.

Didomi: Does it support IAB TCF?

Yes, it is a registered TCF CMP, currently supporting version 2.2 and later revisions.

Luminance: What do the ninety per cent time-saving claims mean?

They are unattributed marketing figures about time and cost rather than accuracy, published without methodology, dataset or baseline. They are not a measure of how often the software is right.

Didomi: What does it cost?

Not published. Pricing is based on monthly unique visitors and quoted.

Luminance: Who backs Luminance?

It launched in 2016 with backing from Invoke Capital, the fund founded by Mike Lynch, and has since raised further rounds led by March Capital and Point72 Private Investments.

Didomi: Where is consent data stored?
