Logo Yazılım × KidZania İstanbul
An interactive experience built for the Logo Yazılım Software Development Centre at KidZania İstanbul, where children work like a real software team and ship their own projects.
Digital Products & Growth Studio
We build products from scratch, fix the digital assets you already have, and get them ready to sell. Small team — no account managers, no agency layers, you talk to the people who actually build it.
When there's nothing there yet, we build it: mobile apps, websites, branded games and interactive experiences.
If your app is dated, your site is slow or the design has fallen behind, we repair, speed up and modernise it without a rewrite.
A good product still doesn't sell without content and a tidy storefront. We produce your social content and rebuild your e-commerce pages.
Services
We work on a single product or your brand's entire digital presence. Every service has a defined scope and process — no surprise invoices.
Apps built from scratch for iOS and Android: booking, membership, loyalty, payments and customer portals tailored to your business.

About
Gudia Digital is a digital product and growth studio, founded to remove the layers big agencies put in the middle — you talk to whoever is building your project.
We choose to stay small. The people who take on the work are the people who build and deliver it. That's why we deliver what we promised — and say up front when something isn't work we should take.
AboutIf something will be late, we say so in advance. We don't claim to know things we don't.
Working products, not presentations. Every stage produces something tangible.
Source code, design files, accounts — all yours. You're never locked in to us.
Priced for the work done. No hidden line items, no costs added later.
How we work
We don't like surprises. What gets delivered and when is written down before anything starts.
We look at your existing app, site or store. We listen to what you want to build and work out what the project actually needs.
We write the work down item by item, with timeline and budget. Nothing starts before you approve it.
We split the work into stages. At the end of each one you get a version that genuinely runs and that you can see.
Store release, domain, servers — we handle all of it. Support can continue afterwards on a maintenance plan.
We'll review your app, site or store and send you a written list of what can concretely be improved — free, no obligation. Nothing built yet? Write anyway, and we'll talk through feasibility in the first call.
