About Us
This is our Honest Story
A story of two brothers, a broken espresso machine, and a community that helped us build something much bigger than we ever imagined.
Where it all started (2019)
Two brothers, Sergio and Jorge, wanted an advanced espresso machine with pressure and flow profiling. Everything on the market was extremely expensive.
With engineering backgrounds—and no budget—we bought a broken Rancilio Silvia and started building our own machine with an Arduino and a breadboard.
We shared the project in coffee forums, and more people than we expected wanted the same thing: advanced control, without the luxury-machine price tag.
That interest pushed us to take the project seriously.
The first step: Kafmasino ONE
Since we couldn’t afford to build a full machine from scratch, we started with a solid commercial espresso machine, redesigned its internals here in Spain, added our custom PCB and sensors, and built our own firmware and software from zero.
That became the first Kafmasino ONE.
We launched ONE on Kickstarter in April 2021. It didn’t reach its goal — but it gave us invaluable feedback and, more importantly, the conviction to keep pushing.
So we improved everything: firmware, software, components, interface, assembly.
In 2022, we launched it again — this time on our own website.
Slowly but steadily, the ONE began to spread across Europe, the UK, America, and beyond. Reviewers tested it, creators shared it, and a real community formed around it.
By the end of 2024, the ONE had become the foundation that allowed us to grow — the product that proved people truly wanted what we were building.
Designing our own machine from scratch
The success of ONE allowed us to do what we always dreamed of: build a machine entirely designed and engineered by us.
With thousands of hours of testing and the feedback of our users, we began designing our first fully original espresso machine.
The birth of KUBO (2025)
Everything we learned — every prototype, failure, fix, late-night test, and community suggestion — brought us to this moment.
Kafmasino KUBO is not just our next machine.
It’s the first one we were finally able to design from the ground up: every curve of the chassis, every internal component, every board, every line of firmware, every detail of the experience.
For years we dreamed of building a machine that didn’t have to compromise.
A machine that could offer real pressure, flow, and temperature profiling.
A machine that could be smart, transparent, precise, and still affordable.
A machine that any home barista could grow with.
Thanks to everything we learned with the ONE — and to the trust and feedback of the people who believed in us — we were finally able to make it real.
Kafmasino KUBO is the result:
a fully engineered machine, built in Spain, designed to make advanced espresso accessible to everyone.
We Perfect Every Shot
to Your Taste
Hi, we’re
Jorge & Sergio
We’re Sergio and Jorge, two brothers from Madrid who share a passion for great coffee and building things from the ground up. Kafmasino started as a side project—a way to combine our love for espresso with our drive to create. What began as a simple idea quickly turned into a full-blown mission: to design a machine that gives every user full control, precision, and joy in the brewing process.
Kafmasino
ONE and KUBO
After launching our first machine, the Kafmasino ONE, and listening closely to the feedback from our amazing community, we knew it was time to take the next step. That’s why we built KUBO from the ground up—a machine made for every home barista, whether you’re just getting started or looking to master your craft.
KUBO is everything we wished we could build the first time, now made real
More Than a
Machine
Today, Kafmasino is more than just a machine. It’s the result of years of learning, testing, failing, and improving—driven by curiosity, community, and a deep respect for coffee done right.
