NextaGrowth was founded by two performance marketers who combined have nearly four decades of hands-on experience inside the platforms — not just advising from the sidelines. We have scaled brands, rebuilt broken ad accounts, and spent tens of millions of dollars profitably. This is what we do.

Most agencies optimize for vanity metrics — clicks, impressions, follower counts. We optimize for one thing: profitable revenue at scale. That clarity shapes every decision we make inside a client's account.
We take on very few clients at a time — deliberately. Not because we can't handle more, but because elite execution demands real attention. Every brand we work with gets the same focus we'd give our own money.
We do two things — Google and Meta. We do them exceptionally well, and we don't dabble in everything else to seem bigger than we are.
Every optimization is hypothesis-tested and measured. Gut feelings don't scale. Repeatable systems do.
We build sustainable growth engines — not short bursts that evaporate when the campaign ends. Our clients stay because the results keep coming.
You see everything — real numbers, real decisions, real explanations. No smoke, no mirrors, no hidden markups.
Two veterans who've seen every corner of the industry. Between them: agency leadership, Fortune 500 campaigns, direct-to-consumer growth, lead generation at massive scale, and a combined track record that speaks louder than any fake paid endorsement.
Co-Founder & Head of Performance Marketing
Brian has been building and scaling paid media strategies since the mid-1990s — long before "performance marketing" was even a job title. With 25+ years navigating every major platform shift in digital advertising, he is one of the most seasoned practitioners in the space.
Before founding NextaGrowth, Brian served as CEO of Addictive Results Marketing, where he built and led the agency from the ground up — developing the Vortex Ads Method, a proprietary multi-platform scaling system designed specifically for ecommerce and lead generation brands. Prior to that, he held senior roles at A4D Inc. and MUNDOmedia Ltd., two of the performance marketing industry's most respected networks.
At Search/eLocal he developed industry pioneering tech and strategy, along with massive contracts with every possible enterprise partner to help grow the business from a sub $100M operation to multiple $Billion dollar valuation in under 3 years.
Brian has personally managed hundreds of millions of dollars in ad spend across Google, Meta, and beyond including native, TikTok and others including Applovin. He has been through every major algorithm overhaul, every platform policy change, and every market cycle — and he knows how to turn disruption into competitive advantage. His specialty: making the numbers work when others say they can't.

Co-Founder & Head of Growth Strategy
Chad's obsession with marketing started at age 15 when he picked up Ogilvy on Advertising and never put the mentality down. What followed was 15+ years of experience across Fortune 500 brand marketing, enterprise sales leadership, and high-stakes performance media buying — a rare combination that gives him both the strategic altitude and the in-the-weeds execution ability that most marketers never develop together.
Before co-founding NextaGrowth, Chad held a Senior SEM Media Buyer role at Fresh Clean Threads, scaling paid search for one of the fastest-growing apparel brands in the country. He also built expertise inside Fluent Inc., Earnware Corporation, and A4D Inc. — companies at the cutting edge of performance and data-driven marketing.
Chad has generated over $100 million in revenue for the brands he's worked with across ecommerce and lead generation. His edge is an unusual ability to connect the macro brand story to micro ad mechanics — bridging the gap between what a company is trying to say and what actually makes a customer click, convert, and come back.

"We both worked on the inside of performance marketing for over a decade before we ever ran an agency. We've sat where our clients sit — under pressure to grow, with a budget on the line. That's why we treat every account like it's our own money. Because we know exactly what it feels like when it is."
Brian Osterhout & Chad MacKenzie
Co-Founders of NextaGrowth
There are thousands of agencies running Google and Meta ads. Very few of them are run by people who have actually done this at scale, for years, under pressure. Here's what sets us apart.
No offshore execution, no account managers learning on your dime. Every strategy and every optimization comes from senior-level professionals who understand your market.
We don't offer SEO, influencer marketing, or brand activations. We do Google and Meta — and we have mastered those two platforms in a way that generalist agencies simply cannot match.
Brian and Chad have navigated every major platform change over the past two-plus decades. That institutional knowledge means your campaigns are shaped by pattern recognition most advertisers don't have access to.
We deliberately limit our client roster. When we take you on, you get direct access to the founders — not an account coordinator who started last month.
We bring proprietary frameworks built over years of real-world testing — including Brian's Vortex Ads Method — designed to scale ecommerce and lead gen brands profitably and predictably.
Chad's Fortune 500 brand marketing background combined with Brian's direct-response agency expertise means we think about growth holistically — not just in terms of cost per click.
We don't chase clients.
We keep them.
Most agencies are built around acquisition — winning new business, onboarding the next brand, moving on. We built NextaGrowth around the opposite idea: that the best measure of our work is how long people stay.
The answer, consistently, is a long time. Not because we lock people into contracts or make it hard to leave — but because they're growing, they trust us, and they know we're genuinely in their corner. When you work with us, you're not a line item on a roster. You're a partner, and we treat you exactly like that.
That's not a positioning statement. It's just how Brian and Chad are wired. Looking out for the people we work with isn't a strategy — it's a value system. It shapes every recommendation we make, every budget decision we advise on, and every conversation we have. We'll always tell you the truth, even when it's not what you want to hear. Especially then.

of clients stay year over year
Our entire business model depends on our clients growing. That alignment means we are never tempted to recommend what's easiest — only what actually moves your numbers forward. Your win is ours.
We will tell you when to pull back spend, when a campaign isn't working, and when a budget could be used more effectively elsewhere. Real partners tell you the truth. That's what we do.
Long-term relationships mean we develop a deep understanding of your customers, your margins, your seasonality, and your goals. That context is something a new agency can never replicate. It's built over time.
We don't advertise heavily. We grow through referrals and retained clients — which means every partnership we have is a direct reflection of our work. We take that seriously every single day.
"We've never had to chase a client to stay. When someone's ROAS is climbing, their cost-per-acquisition is dropping, and they can see exactly what's happening and why — they don't leave. They send their friends. That's the business we set out to build, and it's the one we have."
