CLN Athletics x R3 x Junipeer: A Unified Commerce Ecosystem Now Live on Shopify

CLN Athletics Levels Up Its E-Commerce

CLN Athletics is a Swedish sportswear brand known for its clean, minimalist design and is made for everybody. With a strong focus on performance and simplicity, the brand continues to grow by creating apparel that supports both movement and mindset.

To take the next step in its digital journey, CLN Athletics made the strategic decision to move from Jetshop to Shopify. The move brings the flexibility and scalability needed for continued growth.

We’re proud to be part of this transformation alongside R3, CLN’s new digital agency partner. Together, we’ve built a connected ecosystem that supports the brand in its journey: combining R3’s creative and technical expertise with Junipeer’s plug-and-play integrations that seamlessly connect Shopify, Fortnox, and Qliro.

R3 led the design and development of the new Shopify store, rethinking the user experience, migrating products, customers, and orders from the previous platform, and delivering a more stylish, more stable, future-ready e-commerce foundation for CLN Athletics.

With Junipeer as the integration layer (iPaaS), CLN Athletics now runs a fully connected commerce environment: modern, automated, built to scale. 

Here’s how the full setup looks:

• R3 Reklambyrå leads design and development.

• Shopify powers the storefront.

• Fortnox manages accounting and everyday finances.

• Qliro ensures smooth payments.

• Junipeer iPaaS connects it all.

We wanted a setup that supports our brand experience from start to finish. With R3 and Junipeer, everything is connected — orders, payments, and accounting — so we can spend our time creating value for our customers instead of fixing processes. — Simon Hallberg, E-commerce Manager at CLN Athletics

Junipeer and R3: A Perfect Fit

R3 Reklambyrå is a full-service digital agency that helps brands grow through design, technology, and strategy. Sharing the belief that the right integrations are key to e-commerce success, R3 chose Junipeer as a trusted integration partner.

Our role is to support R3 with plug-and-play integrations that connect core systems in a way that prioritizes a seamless customer experience. 

CLN Athletics, a joint client, is a great example of how the collaboration between creative and technical partners can result in a truly unified commerce environment.

For us, integrations are what turn technology into experience. With CLN Athletics, Junipeer handled the complex backend connectivity, allowing us to focus fully on design and customer experience. The result is a stable, fast, and future-ready e-commerce environment. — Joakim Eriksson, Digital Chef at R3

CLN Powered by Collaboration

This collaboration shows how strong ecosystems are built — when merchants, agencies, and tech partners work closely together with a shared goal. CLN’s new setup is super lean and fully automated. Using Shopify + an iPaaS is simply unbeatable for quick GTMs and flexible growth over time. — Lukas Rogvall, Head of Commercial at Junipeer.
