The cusp.

Cusp: the point where change begins. Where potential gathers before it takes shape. We build at that edge — attending to the invisible details that separate the ordinary from the memorable.

Patience
Time is the rarest material. We spend it on details.
Obsession
The interface, the API, the 03:00 cron — one standard.
Passion
We make what we want to use. Then we make sure others do too.

What we make.

Software and hardware, built in-house. Each product is a long bet — designed, shipped, and supported by the same hands.

YourWebTech

Domains and static hosting, the Swiss way.

YourWebTech is a Swiss accredited registrar and hosting platform built for craftspeople. Register .ch and .li, ship a static site in minutes, and never think about the infrastructure underneath.

How we work.

Three principles, held close as we shape each thing we make. Amid the race of modern product development, we choose slow craft and hands-on care—each product a deliberate act, not a passing trend.

In-house only
We only build what we will own and operate. Every product on this page is ours to ship, support, and outlive — no client projects, no work-for-hire.
Products Ownership Operation
Software and hardware, together
Domains, dashboards, devices. The boundary between screen and object is where the most interesting work lives — and where a studio with both disciplines under one roof can move differently.
Software Hardware Both
Slowly, on purpose
A small portfolio, each piece built to be around for a decade. No roadmap by quarter; no churn by design. We add a product when it earns the room — not when the calendar suggests one.
Patience Long horizon Low churn

Principal-led,
by design.

Cuspar is an independent Swiss studio. Every engagement, every line of code, every support reply — handled by the person who designed the work.

Small by intent. Each product here is shaped, built, and tended for the long run—the same hands at every stage. We choose craft over quantity; better two things lasting than many.
