What Gunbrain does

Most campaigns reach everyone on a site. Gunbrain reaches people based on what they have done. It finds the ArmanetIDs most likely to buy, click or sign up, and puts your budget there first. Less waste. Lower cost per customer.

It is the targeting Meta and Google are known for, built for the firearms industry, on data no one else has.

Niche product? Even better.

Every shooter reads the same sites. Only some of them reload, shoot past 600 yards or want a suppressor. Gunbrain finds the ones who match your catalog.

Specialty brands cut cost per customer by a median of 66%. Broader brands and retailers cut it by 47%.
