Design, production, storefront, shipping - all from one workshop in Belgrade.
KASTM started in 2024, from a simple problem: Balkan creators were trying to sell merch to their audience - and losing the battle before it began. Global print-on-demand platforms were shipping t-shirts from Latvia, Estonia, or Poland. Packages took two to three weeks to arrive. Print quality swung from order to order. When something went wrong, the creator was the one answering complaints - dealing with support teams that didn't speak the language and didn't understand the market.
The problem wasn't technology. That existed. The problem was that the whole supply chain was built for someone else - American or Western European creators shipping thousands of units a month, for whom three-week delivery is fine. For a Balkan creator selling fifty or five hundred pieces a month, the math doesn't work. Too expensive per unit, too long to wait, too much risk.
KASTM was built to fill that gap. One workshop in Belgrade. Print on-site. Packing and shipping from Serbia. Communication in the creator's own language. Revenue share instead of upfront costs, so creators could start without risk. From the first order to today - same model, same workshop, same team that knows every shipment by name.
The easiest way to make fast money is a cheap t-shirt with a logo on it. We don't do that. A design a fan won't wear after the first wash doesn't build anything - except a pile of complaints. Every piece we make has to be something we'd wear ourselves.
We earn only when your merch sells. No subscriptions, no setup fees, no minimum orders you have to buy. If a design doesn't work, we change it - and you lose nothing. This is how we designed the model from day one, and we don't plan on changing it.
Everything is printed, packed, and shipped from Belgrade. For Serbian orders - two to three days. International orders leave the workshop the next business day. Not because we're small (though we are) - because we don't invent middlemen where none are needed.
Every creator we work with gets access to their portal. Sales, orders, stock, payouts - all in real time. No PDFs arriving on the fifth of the month, and no "how much did I earn this month" questions that go unanswered.
Belgrade, one workshop, all production equipment on-site. No outsourcing, no "our partner in Poland", no blind spots in the chain. When a creator asks "where's my package" - we know the exact answer, because the package was here half an hour ago.
The kickoff call takes 30 minutes, it's free, and there's no commitment. Tell us what you do - we'll tell you what it looks like as merch.
