Sick of 6sense/Clearbit giving me useless corporate IP data. Any tools doing actual individual visitor ID?

Our marketing team is spending a fortune on intent data and reverse IP lookups, but it's getting borderline useless with remote work. Knowing that someone from amazon visited our pricing page tells my sales team absolutely nothing.

Are there any tools out there that can actually de-anonymize visitors at an individual level anymore, or has privacy/compliance completely killed that? What kind of reveal rates are you guys seeing on B2B traffic these days?
