coolgift customer success story with teeinblue

Coolgift is a personalized gift webshop for the European market. The brand focuses on photo and text personalization. From t-shirts, hoodies, drinkware to posters and aprons, all built around customers' own photo or name. Unlike most stores, Coolgift runs on its own custom-built platform using Sylius (Symfony PHP), rather than on an off-the-shelf platform.

Challenge: Finding a Product Customizer That Works Outside Shopify

Coolgift's biggest challenge was their platform. Almost every personalization tool on the market is Shopify-first. Finding one that could integrate with a custom stack was a real constraint.

The team also didn't want to build their own personalization engine. Live preview, photo upload, multiple layouts, and print-ready output all take time to build right. A dedicated tool could do it better.

They needed a solution that offered:

Smooth integration with a non-Shopify, self-developed platform
A native, form-based personalization flow, not a free-form canvas editor
Real-time live preview so customers see exactly what they're ordering
Reliable print-ready file output for their POD partners
Enough flexibility for complex, multi-layout products with photo upload and editable text
AI photo effects to offer more than a flat photo-on-product

Solution: Connecting with Teeinblue Boundless to Scale Personalization

Coolgift needed a tool that could plug into their own platform, not the other way around. That's when Teeinblue Boundless came into the picture. Teeinblue Boundless brings the power of product personalization to any e-commerce platform beyond Shopify, making it easier than ever to offer custom products. Whether you’re using WooCommerce, Magento, Shopline, or any other website builder, Boundless integrates effortlessly.

Connecting Custom Platform with Teeinblue Boundless

The Boundless integration was the key. It lets Coolgift connect Teeinblue to their own Sylius shop instead of forcing a move to Shopify. Because Coolgift owns the storefront, they have the flexibility to shape the cart, checkout, and overall customer experience exactly as they want.

Compared to Shopify, the integration requires a bit more setup. Features like syncing mockups with product variants require a bit of extra configuration on Coolgift's side. That extra work is relatively minor, though, compared to the flexibility of keeping their existing Sylius storefront and customer experience fully under their control. Once in place, the Boundless integration works seamlessly with the Coolgift store and workflow.

Building Custom Products with Ease and Flexibility

With Teeinblue’s artwork-template system, the Coolgift team can create highly customizable products with ease. It lets the team create products with multiple layers, layouts, and personalization options like custom text and photo upload. Their customers can switch between layouts smoothly without breaking the design.

The Coolgift team also values features such as live preview, automatic print-file export, and Gen AI effects. The live preview helps shoppers see exactly what they're ordering before checkout, which reduces confusion and lowers return rates. The automatic print-file export sends production-ready files straight to the fulfillment partners without any manual processing. Besides, the built-in Gen AI effects enable AI-powered transformations such as turning customer photos into personalized line art, all within the same personalization flow.

On top of that, Teeinblue rarely forces a fixed template. Whatever product or personalization idea the team has in mind, they can usually build it exactly the way they envisioned. That freedom is what keeps Coolgift creating new things and testing various product design ideas.

Result: A Full Product Line, Built on Their Own Platform

Teeinblue made it possible to launch a full personalized product line on a self-built shop, without developing the personalization technology in-house.

The team can take a product from concept to live, with photo upload, editable text, multiple layouts, and a working live preview, in a fraction of the time it would otherwise take. They can also keep expanding the range quickly. It's opened up new product directions, like AI-styled customer photos and underserved niches in their market.

As the team puts it:

"Teeinblue has become a real part of how we build at Coolgifts, and it keeps giving us room to try new ideas. For a small team running its own platform, that's the real change: we can compete with much larger personalization shops while keeping full ownership of our storefront."
