About us
We built this because B2B marketing deserved better.
Castleberry Media was founded on a simple belief: good B2B companies shouldn't have to burn budget on campaigns that vanish the moment they stop running. We build infrastructure that compounds.

Our story
Then and now
B2B marketing was rented attention
Campaign bursts, one-off events, content that vanished the moment the budget ran out. Companies were paying premium rates for visibility they couldn't keep.
We bet on owned infrastructure
Instead of buying placements on someone else's audience, we built our own publications, our own newsletters, our own audience graph in 30+ B2B industries.
Pipeline that compounds, not vanishes
We operate 20+ niche publications, serve clients across the Americas, and help B2B brands stay in front of their buyers every single day, not just when the campaign is live.

How we're different
What you get with us
Three things that don't show up on most agency decks.
We own the channels
Most agencies rent attention from platforms. We sponsor inside our own newsletters, sites, and communities, with the audience relationship in our hands.
We measure presence, not impressions
Branded search, share of voice, and inbound velocity are the numbers we report on, because they're the numbers your CFO actually cares about.
We stay when the campaign ends
Most engagements compound. Owned distribution keeps working long after the launch quarter, which is why our clients renew at over 90 percent.
Want to see what compounding looks like?
30 minutes. No deck. Just a straight conversation about what you're trying to build and whether we can help. If we're not the right fit, we'll say so.
