Tool
RB2B
Also known as: rb2b.com
US-focused visitor identification tool — reveals anonymous website visitors at person level (does not work in EU due to GDPR).
RB2B (Person-level identification) reveals which individuals visit your site, not just which company. Powerful for US targeting, but GDPR-restricted in EU.
EU equivalents: Vector, Albacross, or Leadfeeder (company level only, GDPR compliant).
