About ADGY: a team of operators who own and run their own ecommerce brands and grow clients with the same system. Includes the operator story, owned brands, how we work, how we train, our principles, and the team.

Who we are

We are not just an agency. We are operators.

ADGY is a team that owns and runs its own ecommerce brands. The same people, the same dashboard, and the same discipline that grow our businesses are the ones we put on yours. When we recommend something, we have already tested it on our own money.

Eight years operating. Two brands of our own. One system we run on every account.

Skin in the game

We run real businesses
with our own money.

Most agencies have never carried a P&L of their own. We have. Alongside client work, we own and operate our own ecommerce brands, with real customers, real margins, and real lessons. Everything we recommend has already been pressure-tested where it costs us, not just you.

We are executors first, with the discipline to ship every week, not to let plans rot in a deck.

Sadje v pisarni
sadjevpisarni.si

Our own office fruit-delivery brand, a B2B subscription trusted by teams at Mercedes-Benz, Porsche, BMW, Jeep, DSV, Roche, and 300+ companies. Real recurring revenue, real retention, real lessons we bring straight to your account.

Visit the brand

Real people, real businesses, real skin in the game. Not consultants reading from a playbook.

Our own brands have generated close to nine figures in revenue and a net seven-figure profit since we started.

And running them taught us every level of the business, not just the marketing: warehouse and inventory management, supplier and contract optimization, integrating operations into accounting software, and unit economics down to the cent. That is how you reach best-in-class margins, and it is what we bring to every brand we work with.

It started small, and for real. David Žalec began with a laptop, 1,000€ in his pocket, no outside investor, and a 10-month-old baby in his lap. No safety net, just the work. Everything ADGY is today was built from there.

How we work

Strategy is common.
Execution is the whole game.

A plan is only worth what you act on. We treat execution as a discipline: a weekly cadence of shipping, measuring against the numbers, and adjusting. No quarterly silence, no fluff reports.

Weekly shipping

We ship every week

Something real goes live each week, a page, a flow, a campaign, a test. Momentum compounds; decks do not.

One shared channel

Slack, not silence

You are in the room with the people doing the work. Direct line, fast answers, no account-manager telephone game.

Measured, not guessed

The dashboard decides

Every move is checked against profit in your dashboard. If it does not move the number, we stop doing it.

When the same team plans, builds, and measures, nothing gets lost in the handoff. That is how growth compounds instead of leaking.

Always evolving

We train like Olympians.

Olympians do not train alone. They find the best coach in every discipline, absorb everything they know, and keep evolving. We train the same way. CXL, top practitioners, relentless operators: we learn from the best, digest it, and bring it straight to your account.

That is the Wall of Proof. We have racked up more certifications than we care to count. Not for show, for skill. Each badge is a discipline we can put to work for you, from product marketing to persuasion architecture. We train across fields so we drive real growth, not just deliverables.

Official badges are being issued by CXL. Until then, all certifications are verified on David's LinkedIn.

What we stand for

Three principles
we actually run on.

We accept no limits

No settling for mediocrity

We are here to make change, not noise. We push for outcomes that matter and keep raising the bar on what counts as good.

We are inclusive

Different backgrounds, sharper work

Our hiring, communication, and promotion celebrate radically different perspectives. The range is what makes the work better.

We own it

We take responsibility

We make the hard calls and stand behind them, even when the consequences are not comfortable. We own the result either way.

We only want long-term partners: people with vision, building something meaningful. We think long-term because we are building for the long-term too.

Meet the team

Real people, real businesses.

Founded by David Žalec, a lifetime athlete and active competitor who holds the same standard in sport and in business. That competitive standard runs through the whole team: people who own outcomes, sweat the detail, and keep score against profit.
