Every day, hundreds of companies visit your website. You don't know they're there. You can't see their name in your analytics. They leave, and if they don't convert, they're gone - and you have no idea who they were.
IP-to-company enrichment changes this. When a visitor arrives from a recognisable corporate network, their IP address can be resolved to the company that owns it. That gives you - in real time, before the page even finishes loading - the company name, industry, size, and type.
With this data, you can personalise immediately. An enterprise software company visiting your pricing page sees the enterprise case study and the security certifications. A 10-person startup sees the Starter plan and the fast-setup messaging. Without enrichment, they both see the same thing.
How accurate is it? Enterprise companies on corporate networks match at 80-90%. SMBs and remote workers on residential or VPN connections match at lower rates - often 30-50%. This is fine. Even a 50% match rate means half your traffic suddenly has context attached to it.
Is it GDPR compliant? Yes - with caveats. IP-to-company enrichment resolves to a company, not an individual. It's treated as business data, not personal data, under most EU legal interpretations. You should disclose it in your privacy policy. But you don't need a consent banner for it.
How to implement it: with Mister Chameleon, enrichment is fully automatic. You install the snippet, and enrichment runs asynchronously on every request. You don't need to configure anything beyond specifying your data region. Match results are available to the decision engine within the same page load.
The most important thing to understand about IP enrichment is that it's not a silver bullet - it's an input. It's most powerful when combined with behavioural signals (page history, CTA clicks, form interactions) and intent scoring. Together, these give you a complete picture of who's on your site and what they need from you.
