JaJuMa A Magento & Hyvä Agency Forged by Experience

We didn’t set out to be an agency.
We were merchants frustrated by broken platform promises, so we built the solution we couldn't find.
That journey - from our own first client to Hyvä pioneers - is the foundation of how we partner with you.

OUR STORY

WHY WE DO

WHAT WE DO

We are an owner-managed full-service e-commerce, Magento & Hyvä Themes agency from the Stuttgart region.
Initially, as probably the first provider of standard software and SaaS solution for online marketplaces on the market, we have continuously expanded and extended our service offering over the years.

In addition to our online marketplace solution, we now also include "normal" online stores as our clients and support our clients with comprehensive services around their e-commerce business. From conception, design, development and optimization of their processes and systems to operation and continuous monitoring and development.

Based on requirements and experiences from our client projects we now offer a range of Magento Extensions.
Extensions that solve real problems for Magento merchants, are cutting-edge and innovative.
And we are an active member of the Hyvä & Magento communities, offering Free Extensions, compatibilty modules as well as help fixing bugs and adding new features through merge requests.

Our exciting journey from being Online Marketplace founders to being the Marketplace Agency, up to the Full-Service E-Commerce, Magento & Hyvä Themes Agency from Stuttgart we are today:

We Know It Started With a Problem
You Know All Too Well

JaJuMa - Magento & Hyvä Agency - We know the client view!

In 2011, We Weren't A Magento Agency.
We Were You.


We were merchants with a clear vision:
To launch a premium online marketplace for delicatessen goods.
We needed a platform that was powerful, flexible, and truly scalable. What we found instead was a challenge. We saw firsthand the frustrating gap between what e-commerce software promised and what it actually delivered. The market was full of solutions that were either too rigid, too complex, or simply not built for the ambitious future we had planned.


Magento Association Bronze Member-Badge

Faced with this roadblock, we made a pivotal decision:
Instead of compromising on our vision, we would build the solution ourselves.
We dove headfirst into the world of Magento, not as developers-for-hire, but as our own first, most demanding client.
That journey, born of necessity, laid the foundation for everything JaJuMa is today.

We Love Our Philosophy:
Build the Solution
You Wish You'd Found

That Early Experience Of Being The Client Shaped Our DNA.


It taught us that successful e-commerce projects are built on more than just code;
they’re built on a foundation of true partnership, absolute transparency, and a shared definition of success.
Our core philosophy is simple:
We strive to be the partner we wished we could have found all those years ago.


This philosophy manifests in how we work every day:

Fairness and Transparency:

Because we've managed our own project budgets, we know that trust is paramount.
We believe in clear, reliable agreements and honest communication, even when the conversations are difficult.
You get affordable rates and a partner who is invested in your long-term success, not just the next invoice.

An Obsession with Quality:

We learned the hard way that software must do more than just "work."
It must be robust, secure, performant, and flexible enough to grow with your business.
We build solutions designed for the real world, capable of meeting the most demanding requirements because we've had to meet them ourselves.

Celebrating Shared Success:

Our ultimate goal is to foster long-term, successful partnerships.
We're genuinely excited to see our clients thrive, and we have a long-standing tradition of celebrating every successful project launch with a custom "Go-Live Cake."
It's a small gesture that represents a big belief:
Your success is our success.
