Xalveon Studios builds digital products that load fast, look clean and respect your users' data — from first sketch to live.
Xalveon Studios
Apps. Websites. Branding.
An independent digital studio from Germany. I build my own apps — and put the same craft into software, websites and branding for companies. Privacy-first, considered, built to last.
What I do
Four disciplines. One signature.
I build digital products that feel fast, honest and timeless — and treat every client project like my own.
Web development
Websites and web apps that load in seconds and stay GDPR-compliant.
Design & branding
Logos, identity, UI. Reduced to what actually lands.
Content
A presence and reach that fit the brand instead of shouting.
How I work
Plan. Build. Verify.
No black box, no surprises. The same process I use to build my own apps.
Plan
Understand first, then design. A clear spec and design direction before the first line of code.
Build
Built like my own product — complete, clean and without ballast. No prototype sold as finished.
Verify
Checked, tested, proven. Before "done" comes the proof that everything works — on real devices.
Why Xalveon
What separates me from the standard agency
Everything from one hand
Design, code and copy from the same person — no hand-off losses, no ping-pong.
Privacy-first by default
Local-first, no tracking without reason. GDPR isn't an afterthought here, it's the starting point.
No running costs where none are needed
I build so your product doesn't pay monthly rent to a cloud.
High standard
Planned, verified, cleanly handed over — no prototype sold as a product.
My own apps
I don't just build for others.
My own products are the proof: the same craft I sell goes into everything that carries my name.

FAQ
The honest answers upfront
Are you a team or one person?
One person: Xalveon Studios is the independent studio of Jack Mausolf. Design, code and copy come from one hand — that's why it all fits in the end. For you, that means one point of contact and no friction losses.
What does a project cost?
Honestly, it depends on scope — a website isn't an app ecosystem. Tell me what you have in mind and you'll get a clear estimate instead of a flat rate that helps no one.
Do I own the code and design?
Yes. After completion, the code, design and all source files are yours. No vendor lock-in, no monthly rent for your own product.
