Contact — Celis, Seoul
Tell us what you're building.
Start with whatever you have — two sentences, a reference site, or a full brief. Nothing needs to be finished before you send it.
Your message goes to Wanwoo Sim, the founder of the studio, not to a sales queue, and you will have a reply within one business day on your clock. There is no call to book first — if it turns out a call helps, we will arrange one then.
Or just email us
The form is a convenience, not a gate. Plain email reaches the same person and gets the same reply time.
sww@celis.co.krWhat happens next
You get questions, our read on what is feasible, and a price band — within one business day. Seoul runs ahead of the US and Europe, so an email sent at the end of your day meets our working morning.
Where it helps, we then build a working preview of one key screen and deploy it to a URL you can open, before any contract or deposit. We take on a limited number of these each month; if we are full, the reply says so.
After that comes a fixed quote with an itemized scope of work and milestones with dates. Most projects fall between $1,500 and $6,000, fixed price.
