How does Vector work?
It’s the first question everyone asks after understanding what Vector does. Let’s pull back the curtain on how we help you build contact-level ad audiences with confidence.
The secret sauce? Device fingerprinting
Vector maps contacts’ IDs by matching work emails with personal hashed emails (HEMs) and mobile advertising IDs (MAIDs). This lets you pinpoint actual buyers more accurately, and place your ads in front of B2B buyers in B2C spaces.
Major match rate upgrades
Match rates in native platforms often struggle to hit double digits. Because Vector operates on device fingerprinting instead of IP addresses or cookies, you see match rates up to 90% on LinkedIn, 45% on Google and Meta, and 30% on Reddit, TikTok, and X.
Off-site research powered by our publisher network
The Vector pixel lives on Forbes, Wall Street Journal, and 400k+ other top publisher sites. When your buyers land there to read up on relevant topics or top competitors, the pixel fires that contact ID back to your Vector instance.

Frequently asked questions
What is contact-based advertising?
It’s advertising built for how B2B buyers actually behave. Instead of targeting anonymous visitors or whole accounts, contact-based ads reach real people verified contacts who match your ICP and are already engaging with your brand.
How is this different from retargeting?
Retargeting chases anyone who’s been to your site.
Contact-based advertising focuses only on known, qualified contacts — using real names, titles, and companies, so you spend less on noise and more on buyers who matter.
Where can I run contact-based ads?
Everywhere your audience is. Vector connects your contact data to LinkedIn, Google, Meta, and other major ad platforms so your targeting stays consistent across channels.
How does Vector know who to target?
Vector sees who’s engaging with your brand on your site, in your ads, and across the web and matches that activity to verified contacts from your CRM and data partners. So your audiences always reflect what’s actually happening, not a static list.
