Small, and we see it through
Ideas, in sync with reality.
EtherXync is a development studio that turns ideas into products that actually work. From screen design to databases, from app store review to running servers, we handle everything a product needs to go out into the world.

We build it and we run it
We don't compete on size. We work with the focus of owning a project from start to finish, and what we learn running our own services goes straight into the projects you trust us with.

How we work
Every project goes through these four steps, in the open.
-
Enquiry and consultation
Tell us what you want to build. No documents needed. We'll find the direction together in a free consultation.
-
Planning and quote
We pin down the scope and give you a clear document with schedule and cost. Nothing to pay until you confirm.
-
Design and development
We share work in progress regularly, so you can see where things stand at any time.
-
Launch and operation
After store listing and deployment we support a stabilization period, and can continue with an operations and improvement contract.

Common questions
How is the quote decided?
After we agree on scope and schedule in the consultation, we send a written quote for that scope. There's no fixed price list, and nothing to pay until you confirm.
How long does it take?
It depends on the scope. You'll get a step-by-step schedule at the consultation, and you can see progress through work in progress along the way.
Do you fix things after launch?
We support a stabilization period after launch. If you need features or improvements after that, we can continue with an operations and improvement contract.
Do I need a spec document?
Not at all. Just tell us what you want to build and we'll find the direction together in a free consultation.
Shall we start a project?
Send us a project, a collaboration idea or any question. We reply within 1 to 2 business days. English is fine.
