Pierre Sima Kunz
Founder, Liquid Interface · Berlin
Rico Stapel at PTYXO, based on Koh Samui. He takes the brief, keeps the project on track and stays your contact after launch. The Liquid Interface team in Berlin does the design and development.
No. Anyone who needs a website, app, brand or AI tool. PTYXO's background is hospitality and yachting, so those projects get extra local know-how.
Every project is quoted individually after a first call. You get a written scope and quote before any work starts.
They learn from your own content: products, prices, FAQs and documents. They can answer customers, book appointments, qualify leads and hand conversations to your staff. Liquid Interface sets them up and runs them as a managed service.
Yes. After a look at what you have, we recommend whether to improve it, move it or rebuild it.
Berlin is five to six hours behind Thailand. You talk to Rico during your working day, and the Berlin team picks up while your evening starts.
