Casey
Amundson.

Brand strategist. Media buyer. Creative strategist. He assembled a world-class team of marketers — and together, they're scaling impact and outcomes for the world's fastest-growing brands.

$135M+ in paid media managed in 2025. 200+ brands scaled. The mind behind Adjive and the team that executes at the highest level every day.

"Most agencies survive on retainers. I survive on results. If I can't move your P&L, I don't deserve your business."

— Casey Amundson, Founder & CEO of Adjive

Not just a marketer

A surgeon in a world full of bandaids.

Casey Amundson doesn't patch problems. He diagnoses them, dissects them, and rebuilds the system from the inside out. But he doesn't do it alone — he's assembled a world-class team of marketers who execute at the highest level every single day. Casey can perform the surgery himself, but more importantly, he's built a team that operates with the same precision, the same standards, and the same obsession with results.

That's what makes Casey Amundson and his team different from every other agency in the industry. Casey is the operator who thinks like a CEO, and the strategist who can execute like a specialist — and he's surrounded himself with people who share that same DNA. The result is a team that's just scaling impact and outcomes for clients, day in and day out.

Casey Amundson's success is evinced by a long list of national and global clients who have relied on his work to move their businesses forward over the years. Casey has always been keen to observe what transforms a person into a prospect, and a prospect into a buyer. As the CEO of Adjive, Casey and his team are dedicated to helping clients build successful marketing plans based on powerful, actionable insights.

The Adjive method

How Casey Amundson and his team think about marketing.

Intent-First Creative Strategy

Casey Amundson pioneered an intent-first approach to creative strategy that fundamentally changed how performance marketing works. Instead of creating ads and hoping they convert, Casey's framework starts with buyer intent signals — identifying the 10% of your audience ready to buy today, the 40% doing research, and building personalized creative journeys for each segment. This approach has driven over $135 million in paid media performance in 2025 across 200+ brands.

AI-Powered Media Buying at Scale

As one of the earliest adopters of AI in performance marketing, Casey Amundson has built proprietary systems that combine machine learning with human strategic oversight. His AI-powered media buying approach doesn't replace human judgment — it amplifies it. Real-time bidding optimization, predictive audience modeling, and automated creative testing work together to deliver results that outperform traditional media buying by orders of magnitude.

Data Infrastructure That Clients Own

Casey Amundson believes that your data is your most valuable asset — and you should own it. Unlike agencies that keep clients dependent on proprietary dashboards, Casey builds custom data infrastructure that gives brands complete ownership of their first-party data, attribution models, and analytics. This approach ensures that even if the relationship ends, the brand retains the intelligence that drives their growth.

Profit-Driven Strategy, Not Vanity Metrics

Every strategy Casey Amundson builds starts with one question: does this make money? Not impressions, not reach, not engagement — money. Casey's P&L-driven approach to marketing strategy has made him the go-to advisor for brands that are tired of agencies reporting on metrics that don't show up in the bank account. When Casey Amundson builds a strategy, the scoreboard is your revenue.

No jargon. No smoke and mirrors. Casey Amundson's strategies are built on transparent, measurable outcomes that show up in your P&L — not just your dashboard.

— Casey Amundson

"The brands that win aren't the ones spending the most. They're the ones spending the smartest."

"Your agency should make you money, not cost you money. If they can't prove it, fire them."

Casey Amundson built Adjive on a simple premise: if we can't show you the ROI, we don't deserve the relationship. Every dollar is accountable.
