Websites, bookings, AI agents — for your business.
Booking systems, custom workflow automation, and AI agents — built once, owned by you. No monthly SaaS, no platform lock-in. One studio ships both pillars, end-to-end, for German-speaking SMBs.
One package, end-to-end. Built once, yours to keep.
Multilingual marketing site, online booking & tickets, self-hosted CMS that doubles as admin panel, and GDPR-conscious infrastructure — all built end-to-end and owned by you. No monthly SaaS fees, no platform lock-in.
Multilingual Marketing Site
German default, English auto-detect. Hero, highlights, gallery, events, FAQ, opening hours, and contact — all editable from the CMS.
Booking & Ticketing Flow
Multi-step booking with date picker, time slots, guest counts, add-ons, and confirmation with calendar .ics download and reference numbers.
Self-Hosted CMS & Admin Panel
Payload CMS as the admin panel and lightweight CRM. Manage events, bookings, tickets, and site content — no code required, no monthly fees.
AI agents and automation, built for the way you work.
Custom AI agents, workflow automation, and integrations between your existing tools — built end-to-end and owned by you. The boring middleware and the smart layer, shipped together by one studio.
Workflow agents that take work off your team
Multi-step agents that read your inbox, your CRM, your ticketing system — and act. Not chatbots: working colleagues that ship outcomes.
RAG pipelines on your own data
Knowledge agents that answer questions from your docs, contracts, and product manuals — with citations. Self-hosted; your data never leaves.
Integrations and middleware that just work
Quiet pipelines between the tools you already use — booking systems, CRMs, accounting, calendars. The plumbing nobody wants to build.
Four phases, no surprises.
A predictable rhythm from kickoff to launch. Progress shows every week, not just at the end.
Discovery
The business, users and technical lay of the land get a deep look before any code. You leave this phase with a written brief and a defensible plan.

Wireframes → high-fidelity design → clickable prototype. The experience and design system get validated before development picks them up.
