The story behind our apps

In 2021, my wife started her first Shopify store, and I helped her get it up and running. When we ran our first sale, we installed a price editor app. It changed the prices incorrectly and couldn't restore them, leaving us to fix the catalog manually.

I went looking for an alternative in the Shopify App Store, but couldn't find one I trusted with something as important as pricing. So I built my own, with safety and backups at its core. Where every price change could be rolled back. That became Platmart Bulk Price Editor.

Later, the same store ran into another problem. Different colors of the same product were separate listings in Shopify, but shoppers needed an easy way to move between them. I couldn't find a good solution, so I built one. That became Platmart Color Swatches.

Both apps started with real problems in stores I still help operate today. It means I'm not just building for Shopify merchants - I'm one of the people using these tools day to day. That merchant perspective still shapes every product decision we make.

How we build

The standards behind every Platmart app

Customer-funded and built for the long term

Platmart started as a side project in 2021. Today, it's my full-time work, funded entirely by our customers. That gives us the freedom to focus on merchant needs and build for the long term.

Built by an experienced software engineer

I have been building software since 2011, as a developer, team lead, and CTO. I built Shopify products with FORSBERG+two and led engineering at Busfor (acquired by BlaBlaCar). That experience goes into every Platmart app.

Simple and focused software

We build software we wish existed and want to use ourselves. Instead of adding every possible feature or setting, we design simple workflows that make everyday work easier for merchants.

Stability comes first

Prices, catalog data, and storefront widgets affect live businesses. We introduce changes carefully, avoid breaking existing setups whenever possible, and provide ways to recover when an app changes sensitive data.

Shopify-native by design

We use Shopify's native platform capabilities wherever possible. Building on Shopify's infrastructure helps our apps stay fast and scale smoothly as your store grows.

Real people behind every app

You can ask to speak with a person at any time, and complex issues go to our support team. Every software change is reviewed by someone who understands it, including work assisted by AI.
