01 — OriginHow we became a global operating company.

klickandsell was founded with a simple, stubborn conviction: that the next generation of consumer brands wouldn't be built by marketing agencies or holding companies, but by operators who treated commerce as a software problem. We started with a single category we genuinely cared about — licensed headwear — and grew because we built the tooling that lets one team run what most companies need ten to operate.

Today, klickandsell e-commerce GmbH operates a curated portfolio of category-leading brands across Europe and the United States, all running on a software platform we develop in-house, with a US subsidiary anchored in Connecticut and a flagship retail presence in the Bronx. Two continents. One operating system. Software in, scale out.

Building best in class software for the best customer experiences.

02 — The DNAWhat we mean by "ecom dna."

Most e-commerce companies optimise. We engineer. Each brand inside our portfolio is treated as its own organism — its own voice, its own audience, its own commercial physics — but every brand inherits the same backbone: an integrated software platform we built ourselves, paired with a category-management discipline that turns assortment, supply, and pricing into a compounding growth function.

That backbone is the DNA. It's why we can launch a new label without starting from zero, scale across continents without losing the soul of a brand, and stay profitable through cycles that have flattened louder competitors — because every brand benefits from the same software, the same data, and the same category playbook.

We don't operate brands. We operate a system that operates brands. — klickandsell operating principle

03 — Tech-Driven, by ConvictionWhy we operate like a software company.

E-commerce is, fundamentally, a data business pretending to be a product business. We took that seriously early on and committed to an AI-driven approach across the stack — from category management and pricing to inventory, margin observability, and the internal tooling our team runs on. Where off-the-shelf software earned its place we kept it; everything that compounds our edge, we develop in-house.

That stack gives us the same operational visibility a SaaS company has over its product. Every cap that ships, every campaign that runs, every margin that moves is observable, queryable, and accountable — and it's how a lean team runs an eight-figure operation across two markets, adding brands and categories without adding headcount in proportion.

04 — Two ContinentsGraz and Hartford, working as one.

Our European headquarters sits in Graz. Our American operations run out of Hartford, Connecticut, with a retail flagship in the Bronx and warehousing positioned to serve all of North America. The geography is deliberate: Europe gives us proximity to suppliers and a deep, design-literate consumer base. The US gives us scale, sport-licensed product access, and a market that punishes weak operators quickly. Together, both sides give us access to global talent working closely as one team to execute a single global strategy.

Running both sides of the Atlantic on a single software platform is the hard part — and the part that compounds. Every category insight, every supplier integration, every operational improvement we ship lands in both markets simultaneously.

Operators and engineers. We build the software our brands run on.

05 — The PeopleOnly the best in their field.

We hire deliberately, with a heavy bias toward people who think tech-first. Every function inside the company — operations, marketing, supply, finance, software — is run by someone who treats their work as a system to engineer, not a process to manage. That's the bar, and we don't move it.

06 — What's NextBuilding, slowly, in public.

We're not in a rush. The categories and brands we already operate have years of runway ahead of them, and every iteration of our software makes the next launch cheaper, faster, and better-instrumented than the last. Where we do expand, it'll be along the same axes that got us here: licensed product, lifestyle categories with real cultural weight, and software that turns category management into compounding growth — whether it runs in Graz, Hartford, or somewhere we haven't been yet.

If you're a founder, a brand, or an operator who reads this and recognises the way we work — we'd genuinely like to hear from you.
