Case Study
Built what
no app
could.

"The subscription customization they built using Liquid and third-party tools solved exactly what our app was missing — and customers love it."

— Creatine Gummies Brand, US Supplements DTC

A fully custom subscription block — built from scratch when the app hit its ceiling. Custom Liquid, OS 2.0 app blocks, complete brand control. Exactly what the client needed. Exactly what no plugin could provide.

Why TheDeki

We solve what others can't.

01

Beyond App Limits

When a Shopify app hits its ceiling, we build a custom solution — engineered from scratch to do exactly what you need.

02

OS 2.0 Native

Every build uses Shopify's modern OS 2.0 — sections everywhere, metafields, app blocks. No legacy architecture.

03

You Own It All

Every component is modular, documented, and yours. No black boxes, no vendor lock-in.

04

US, UK & Europe

We work with brands across the US, UK and Europe. Clear async communication, transparent pricing, and timezone-aware delivery.

Our Commitment

We recommend what's
right for you
not what pays us more.

In an era where most agencies upsell complexity you don't need, we do the opposite. If a $30/month app solves your problem, we'll tell you. If you don't need a custom build, we'll say so. Our reputation is worth more to us than any single project.

🎯

Your success is our metric

We measure our work by the impact it has on your revenue and operations — not by how many features we can bill for. If a simpler solution gets you there, that's what we recommend.

🤝

We'll tell you what you actually need

On every discovery call, we give honest feedback — even if the answer is "you don't need us for this." That kind of honesty is rare. It's also exactly why our clients come back.

🔍

No inflated scopes, no mystery fees

We scope only what solves the problem. Every line item is explained. You'll never pay for work you didn't understand, agree to, or need.
