Building the Future of B2B Growth Marketing

Our story

Martech fragmentation and saturation has gone too far.

Our world is flooded with data.
‍
In a perfect world, more data would mean better markets. Products would easily reach the customers that most need them. Buyers would get less spam and find more high-value solutions.

But our world is far from perfect.

Hamstrung by limited ad platforms and an increasingly fragmented yet siloed world of martech tools, GTM teams are forced to jerry-rig their way into scaling a growth engine. They spend hours stitching together data and tools and wasting millions on spray-and-pray campaigns. We think that’s crazy. That’s why we built Primer.

7000+ martech apps to choose from

It’s time for something radically simple and universal

The internet was built for consumer brands, but your B2B product still deserves to be discovered. Thanks to privacy crack-downs, yesterday’s playbook—cookie-based retargeting, pixel hacks, spray-and-pray email—keeps getting throttled while costs on “safe” options like LinkedIn and Search spiral upward.

Primer flips that script.

Turn B2C channels into B2B powerhouses
We pipe in your first- and third-party data, map it to rich company context, and let you build razor-sharp audiences that outperform native targeting on Meta, YouTube, Reddit—anywhere eyeballs roam.

‍Prove performance in real time
Built-in alerts surface costly CPM spikes, sloppy click-thru rates, and audience fatigue before they drain your budget.

‍Expand beyond ads
Audiences shouldn’t live in walled gardens. From ABM orchestration to outbound enrichment, we’re opening every GTM touch-point that matters.

No vendor lock-in, no mystery models—just a single source of truth you can activate anywhere. B2B growth finally gets the modern toolset it deserves.Turn B2C channels into B2B powerhouses

We freakin' love driving real results for our customers

One of our customers from Vouch said it best: “I don’t see Primer as a martech tool. It’s a foundational data layer for our entire GTM.” If this sounds exciting, it’s only the start. Come help us build the future of B2B growth marketing.
