About Us
Five people who'd rather build it right than build it fast.
We started MJ Core Solutions in Spain in 2019 because too many good businesses were being let down by generic websites and half-finished automations. Now we're the team our clients call before anyone else.
How it started
A studio built on being easy to work with.
MJ Core Solutions started with one freelancer, one laptop, and a habit of answering the phone when other agencies wouldn't. Clients kept asking for more — a better site, then automations to handle the leads it brought in, then photography to make it all look as good as the work actually was.
Today we're a five-person team covering web design, AI & automation, branding, and photography — still small enough that you talk to the person actually doing the work, still stubborn about doing it properly.
What we hold ourselves to.
Four things that shape every project we take on.
Clear communication
You always know what stage a project is at — no chasing us for updates.
Fast turnaround
We scope tight and ship on the timeline we agree to, not “when it's ready”.
Strategic thinking
Every deliverable ties back to a business outcome, not just a deadline.
Attention to detail
Spacing, copy, load time — the small things clients notice without saying so.
The people you'll actually talk to.
No account managers, no middlemen — just the five of us.
