If your potential clients’ current recruitment systems are truly borderline archaic (and if you think they can handle having this being pointed out to them in a somewhat aggressive manner), I don't think it's too late in the century for you to consider using the notion of:
drag{ing} someone/something into the 21st century/the modern
world
definition and synonyms
PHRASE
to make a person or organization do things in a more modern way
Synonyms and related
words
To make something more modern or fashionable:
update,
modernize, drag someone/something into /the 21st century/the modern
world...
(from MacMillan Dictionary)
Please note, however, that if this is something that you would consider, I would strongly recommend softening it by replacing “drag” with “bring” in your case, and perhaps you could add the bracketed language:
Our platform will bring your recruitment process [roaring] into the
21st Century [and help prepare it for the next one].
See the first line of this Innovation Warehouse article for an example of the expression (with bring) being used in the recruitment field.
If the above suggestion is deemed unacceptable for any of the concerns raised in my answer or the comments to it, perhaps you could play on the notion of progressing “From a Process to a System” (as that notion is discussed [granted, presumably, based on my reading of the linked ERIC “abstract”] in an article with that title, by Roger Chevalier) and use it with a term that seemingly has a specific positive meaning in your field:
”Our platform will transform your current recruitment activities from a mere process to a[n
efficient] recruitment management
system.
recruitment management system
A recruitment management system (RMS), also known as an e-recruitment
or online recruitment system, is a multi-component software tool
designed to automate and facilitate the processes involved in finding,
attracting, assessing, interviewing and hiring new personnel.
