SDAN · Software Designed Around Need

Every idea starts as chaos.
We build the order.

You bring the idea. We find what it actually needs, then build and run it. Leaner to maintain, quicker to ship.

StudioWho we are

Most software is over-built or under-built. We build only the part that earns its place.

SDAN LTD is an independent product studio. We build and run our own products, and take on a small number of partner projects a year. Less to maintain, quicker to launch, and no bill for features nobody opens.

We work across the modern stack, web, mobile, data and applied AI, and we care more about whether a tool earns its place than whether it dazzles in a demo. We build data-driven first and use AI only where it genuinely helps, because the answers that have to be right come from your data, not a model's best guess. TradeBooked, our booking and payments platform for tradespeople, is where the studio started. It is not where it ends.

We adopt the software nobody else will support. Anyone can spin up a website or app with AI in an afternoon. Keeping it alive when real users, search and payments arrive is the hard part, and it is where most of them quietly fall over. Whether yours was built that way, left behind by a developer who moved on, or simply no longer looked after, we take it over, make it safe, and keep it running for the long term, under your own accounts, the same way we run our own products.

PrinciplesHow we work

The right build, not the big build.

We build what an idea needs and leave the rest out. Less to maintain, quicker to ship, cheaper to run.

You own everything.

The code, the hosting, the accounts, all under your name. No lock-in, no hand-off, no builder you cannot leave.

Native only.

No cross-platform shortcuts for mobile. Your customers feel the difference, so we build native iOS and Android.

No fixed bids.

Fixed prices reward over-scoping. We scope tight and charge for the work that earns its place.

Modern where it earns it.

We reach for AI, ML and the current stack when they pull their weight, not to chase a trend.

No dark patterns.

We make money when the work works, never when someone gets stuck.
