Don't take our word for it.
Take theirs.

Zak Columber is a seriously talented copywriter and marketer who consistently over-delivers.

This isn't just because he's a highly-skilled writer with a relentless work ethic. It's due to the way he approaches every project—with intense curiosity, uncompromising personal standards, and deep respect for both the company's business objectives and the target consumer. That's a killer combination.

More than any copywriter I've ever worked with, Zak eagerly seeks out countless interviews with prospects and customers—to better understand their wants and needs—so he can create compelling copy that truly resonates. He's not just checking boxes here; he actually loves doing this research. And this enthusiasm and passion shine through in every line he writes.

Zak is also a terrific colleague—for many reasons:

• He always shows up authentically as his best self, ready to work with a smile on his face.
• He's a calming influence who doesn't get rattled by tight deadlines.
• He's as open to feedback as anyone I've ever seen, with a "zero ego" attitude.
• He's all about solving problems instead of dwelling on them—whether it's a last-minute tweak or a major pivot mid-project, Zak embraces the challenge with positivity and a "let's do this" attitude.

That's a long way of saying: Zak not only makes any copy, campaign, or project better—he makes any team better.

We have used Zak Columber for several research projects involving both qualitative interviews and surveys. He is a meticulous professional with great listening skills and a desire to get to the truth, no matter where it leads.

He also delivered full transcripts, executive summaries, and recommendations, giving us a clear lay of the land, how he got there, and where we could go next. Can't recommend enough.

Zak is a spectacular addition to any team. He's 1) a ridiculously hard worker, 2) a great writer, 3) an interviewing/testimonial machine, and 4) a joy to be around.

My favorite part about working with Zak, though, was his ability to serve his readers and channel a future version of themselves. It's an insanely special and rare talent in a copywriter. And I'm not just saying that—Zak has the stats to back it up.

In the most recent product launch for our sleep and stress management certification, our team exceeded sales goals by 163%. Zak led the charge in writing all the email journeys, sales page copy, and website content for the launch, and our success could not have happened without Zak's skills, talent, creativity, and work ethic.

Zak is one of those rare copywriters who possesses not only the technical expertise in crafting compelling words but also a profound empathy for the target audience. Having worked closely with him in the health and fitness space, I've witnessed firsthand his deep care and understanding for the people we aim to reach.

Zak has an innate talent for drawing out testimonials and stories from our customers, giving a genuine voice to our coaching programs that resonate with potential students and clients. These narratives don't just promote our products; they tell stories that touch hearts, making PN's message unforgettable.

When it comes to teamwork, Zak is exceptional. His reliability is unparalleled, always delivering on his promises and keeping the team in the loop every step of the way.

Furthermore, Zak has demonstrated an incredible ability to work independently, taking drafts and transforming them into polished email campaigns and sales page copies without any hand-holding. His proactive approach and attention to detail have significantly boosted our conversions.

If you're in the market for a top-notch copywriter who genuinely cares about your audience and delivers outstanding results every time, Zak is your go-to professional.

Zak is one of the most talented and hard-working copywriters I've ever had the privilege of working with. Not only does he excel at creating copy that captivates an audience through masterful storytelling, but he also produces copy that converts exceptionally well.

What really sets Zak apart is his passion for connecting with customers on a personal level through interviews and customer research, and then taking those learnings to craft outstanding testimonials and customer-centric messaging that breathes new life into emails, ads, social, web—or anywhere else you need ridiculously compelling, high-converting copy.

Oh, and then there's the fact that Zak is just a pleasure to work with—easygoing, open to feedback, and brimming with innovative ideas. He's equally effective as a team player and when working independently. His work combines creative flair with data-driven results, consistently delivering exceptional conversion rates.

In any role requiring a strategic mindset, an empathetic understanding of the audience, and a passion for results, Zak is someone I can wholeheartedly recommend.

In my capacity as a Product Marketing Lead at Precision Nutrition, I've had the pleasure of working closely with Zak, a copywriter who truly excels in his field. Zak's expertise extends far beyond writing copy; he genuinely understands our audience, capturing their voices through authentic testimonials that enrich our coaching programs.

On the team front, Zak is a stellar example of reliability and effective communication. His consistent updates keep everyone well-informed, a crucial quality in our remote-first and dynamic work environment. Further, Zak's ability to function independently—transforming concepts into meticulously crafted email campaigns—is not only commendable but has also been a significant driver in boosting our conversion metrics.

Zak has also recently harnessed the power of AI to both speed up his workflow and elevate the quality of his first drafts. This "future-now" approach has been a game-changer, enabling him to dedicate more time to refining and enhancing his work to new levels of excellence.

For organizations or agencies looking for a copywriter who possesses a keen strategic mindset, coupled with an empathetic understanding of the target audience, Zak is an invaluable resource. He is more than just a skillful writer; he's a dynamic contributor who brings value to any project.

I've never worked with anybody that had such an elaborate process for interviewing customers and digging into their pain points. Some of his insights drove a lot of the marketing work that we're still doing today successfully. He's not just a copywriter, he's an actual marketer.

Zak brought a lot of insight into my business. He calls out little mistakes that I would never pay attention to, but are actually hurting my sales and capacity to reach people. And applying his suggested changes has resulted in about a 70% increase in signups!

Zak helped us craft these really good offers, launches, and long-term sales assets. Working with him, we increased top-line revenue by 2.66x over 3 years.

Words are incredibly powerful. Zak knows exactly what to write to capture attention and inspire action. He designed an entire sales page for my coaching program along with an engaging email sequence that generated a ton of memberships.

From the start, he laid out his plan, timeline, and the results I could expect. Then he exceeded on all three fronts. It set the foundation for a thriving coaching program and changed my business. He was always communicative and open to feedback to ensure I felt comfortable with the message we were putting out.

Zak's greatest strength is truly understanding his client's values and their audience. After 16 years in business, I care a lot about my reputation. Zak's copy was tailored precisely to my audience's needs and was written in my own voice.

If you're looking to accelerate your sales in an honest way, don't hesitate to hire Zak.

I've worked with Zak for over three years now. He's written every sales email campaign we've run at my company. That's over a dozen launches, and he's been a huge part of our growth.

What made the biggest difference was his research. Zak interviewed 14 of our customers before writing a single word. He learned exactly how they talk about the exam, what scares them about it, and what finally pushed them to invest in coaching. That changed everything about how we communicate with our audience.

His copy doesn't sound like marketing. It sounds like someone who actually understands what it's like to study for the exam while working full time. That's why it converts.

I'd recommend Zak to any business that wants a copywriter who does the work to truly understand your customers.
