Work with the best ecommerce optimizers in the world

Our remote team is built on top-notch talent

Joris Bryon - Founder

Originally from Belgium, Joris Bryon spent two years in Malta after absorbing 35 years of bad weather in his native country. He now lives in sunny Valencia, Spain.

Bryon is the author of Kill Your Conversion Killers: A Pragmatic Approach to Conversion Optimization for E-commerce (2018). He’s also a guest lecturer at University College Ghent, where he teaches a course called “Data-Driven Conversion Optimisation”.

Most Proud Of:’s amazing team

Most Likely To: Slam his shins on the coffee table, trip over the rug, and turn his clumsiness into a great story once the bruises heal

Marc Uitterhoeve - Conversion Optimization Manager

Marc’s favorite thing of all is analyzing test results, because it’s always a win-win: either the client makes money, or new test opportunities are uncovered. Like everyone else on the team, he prefers making decisions based on data instead of gut feelings.

He lives on the island of Gozo in Malta, where there are no winter sports to challenge his balance… and he likes it that way.

Daydreams About: Getting a novel published and traveling New Zealand in a minivan

Most Proud Of: His decision to move to Malta, where he didn’t know anyone and where he started a whole new job — just to see what it’d bring him

Lauren Tonge - Conversion Optimization Consultant

Lauren is’s lone American, hailing from San Antonio, Texas. She loves the tricky times when reasonable assumptions contradict the data — like when a site’s shipping info seems easy to find, but user testing reveals that it might as well be invisible.

Unusual Talents: Can speak and read some Chinese, which comes in handy when she happens to be in Taiwan

Daydreams About: Buying land and living in the woods, though it would be tough to find her beloved bubble tea out there

Matties Otter - Conversion Optimization Consultant

Matties has worked in online marketing for more than a decade. Once he decided to specialize in conversion optimization, there was no stopping him — he quit his generalist marketing job, became a certified optimizer, and joined the Dexter team.

He lives in the tiny town of Maaskantje, which is famous for being the home of the Dutch Comedy Central black comedy “New Kids Turbo”.

Daydreams About: Getting paid to eat

Unusual Talents: They say white men can’t jump, but they haven’t met Matties

An Vankeer – Office Manager

An swapped rainy Belgium for the sunny South of France where she lives with the Ventoux Mountain in her backyard.

She works remotely as the Office Manager for, assisting with all kinds of projects.

When she is not working, she loves to take her backpack and go hiking in the mountains.

Unusual Talents: Can play along with David Bowie’s Jean Genie on the harmonica, but only a happy few have witnessed.

Daydreams About: Traveling around the world as a digital nomad.

Mark Puts - Lead Developer

Mark is’s lead developer, and loves seeing how his work helps clients grow. He lives in remote Posterholt, The Netherlands, where he got his start in optimization early — at the tender age of 12, in fact.

When he’s not working, Mark is probably thinking about work. Seriously, we can’t get him to stop.

Most Proud Of: Learning the skills that make him a living early on

Unusual Talents: None (that he’ll tell us about)

Why we don’t like the term
“Conversion Rate Optimization”

Quick note: We’re not huge fans of the phrase “conversion rate optimization” because there’s so much more to ecommerce growth than simply improving conversion rates.

There’s user experience. There’s SEO. There’s design and branding.

There are smart partnerships, strategic promotions, and countless other business decisions you make every day to grow your store’s bottom line.

“Conversion optimization” just doesn’t cover it all. That’s why we prefer the term “continuous revenue optimization,” because it focuses on what’s most important: your store’s ongoing growth.

We care about revenue, not rates. But hey, no matter what you want to call it, we’re damn good at it.

Gerjan Horstra

We are very happy with Dexter Agency and highly recommend them. Their A/B testing win-rate is very high, which means they provide us several hundred thousand euros more in revenue per year.

— Gerjan Horstra, CEO of Travelbags
