Strategy without design
is invisible. Design without technology is decoration. We do both.

A first and last name, not a department.

Eduard Costin
Behind Studio Jem is Eduard Costin: born in Bucharest, trained in internet and telecommunications, in Sardinia since 2018. Design and code come from the same hand.
During Covid he built iOS and Android apps for local businesses that couldn't wait for digital any longer, and the Region of Sardinia's platform for the Sardinian language, in its Logudorese and Campidanese variants.
Today he works with hotels, wineries and companies across Italy. The rules haven't changed since day one: few projects, done well, with a single point of contact.
How we work.
Strategy
Then we decide what's actually needed. Often less than you'd expect: a clearer structure instead of twenty pages, three good messages instead of thirty mediocre ones. Value lives in what we remove, too.Design & Build
Design and development move together. You see the project grow in real, testable environments you can open on your phone — not in a PDF of mockups. Every visual decision gets verified where it counts: on a small screen, on an ordinary connection.Growth
Launch is the beginning. We set up analytics and Search Console, measure what actually happens, and correct. If you need SEO, campaigns or content, we handle that too. If you don't, we'll tell you.You talk to who does the work
No layers in between. The person who answers is the person who designs.
We say no
If a project isn't right for us, we say so. It costs one client and saves ten.
We build, we don't assemble
Development happens in house. No black-box subcontracting.
You get everything
Code, source files, access. The project is yours, even if one day you decide to go elsewhere.
From 2018 to today.
2018
The founding
Studio Jem opens in Sardinia. First brands and first websites for the island's businesses.
2020
The first six-figure store
Twenty active clients. Covid brings the first apps, and an online shop passes six figures in revenue.
2022
The Awwwards nomination
The international recognition for the world's best websites. Past fifty projects.
2024
Beyond the island
More than 65 clients, and a luxury resort on the Costa Smeralda among the year's projects.
TODAY
200+ projects
Identity, websites, e-commerce and apps. The method is unchanged: few things, done well.
Companies we've worked with.
