Here's what Primer can do now:

• Primer's match rate to ad platforms (Facebook, Google, LinkedIn) is 60-90% through our process of ad network matching data enrichment.

• Primer can automatically (and continuously) import Companies & Contacts from HubSpot directly into the same Facebook, LinkedIn and Google audiences

• Users can also build custom audiences from our database of firmographic and demographic filters, like revenue, headcount, job title, etc.

How we do it? When most people create custom audiences they're using either a pixel (i.e. cookie) or a work email to match to an ad network's user base. The result is a 10-40% match rate. We use persistent identifiers like:

• Hashed Personal Email Address

• Mobile Phone Number

• Mobile Advertiser ID

• Facebook App User ID

By appending those data points from GDPR & CCPA compliant sources, we're able to create incredibly powerful audiences across Facebook, Google and LinkedIn. That allows you to make emails and ads almost 1:1 (boosting email open and reply rates) and driving more efficient ad conversions (you're only serving ads to qualified leads, you can personalize the copy/creative, and you can target almost the exact same audience on every ad network).

It's pretty potent.
