Concept 01 · Editorial European luxury
Maison Lumière
Booked on feeling, run with precision
Leads with: Website
Discerning clients don't compare price lists — they fall for a mood. Maison Lumière's site leads with quiet serif type and full-bleed calm, while the branded client app runs the relationship: rebooking, memberships, and reminders that feel personal, never automated.
- Editorial website built around imagery and stillness, not menus
- One-tap rebooking and membership renewals in the client app
- Personalized reminders in the practice's own voice and brand
A concierge that never clocks out
Answers at any hour. Knows when to hand off.
Try it. Your production concierge is grounded in your practice's approved services, policies, pricing, providers, and brand voice — so it answers approved questions, explains prep and policies, finds availability and handles booking, rebooking, and waitlists where supported, and explains memberships and rewards. It escalates anything medical or uncertain to your team.
- Explains approved services, prep, recovery, and policies in plain language
- Finds availability, supports rebooking, and joins clients to an approved waitlist — where supported
- Explains memberships and rewards, and follows up with practice-approved messaging
It never diagnoses, recommends a medical treatment, or promises results — a licensed provider always does that. Please don't enter medical details in this demo.
Hi! I'm the Lumière concierge — here any hour. Ask me about treatments, prep, availability, or membership, and I'll help you find the right next step.
Ask the concierge
This demonstration uses our Maison Lumière concept (fictional). Your concierge would be built and branded for your own practice, in your voice, on your approved services.

Zenoti's 2025 benchmark reports strong consumer interest in mobile booking and a wide gap between that demand and the average med spa's online-booking adoption: the exact gap a custom-branded booking experience is built to close.

Questions
Fair questions, straight answers.
Do I have to replace Zenoti / Boulevard / Mindbody?
No. Your platform is designed to connect with the systems you already use, where supported — enhancing them rather than ripping them out. Where a unified replacement genuinely serves you better, we'll recommend it and say why. That call is made with you.
Is membership really a full feature, not an add-on?
Yes — membership and rewards are substantial, independent capabilities: tiers, monthly credits, rollover, guest passes, member pricing, and points on every visit and product. For many practices it's an opportunity to create more predictable recurring revenue.
Can I start with one part and expand?
Yes. Many practices begin with the highest-impact piece — often the branded app or the membership program — and expand in phases as it pays for itself. Your growth planner suggests where to start.
How does the AI concierge stay safe?
It's grounded in your approved services, pricing, policies, providers, and brand voice. It answers approved questions, explains prep and policies, finds availability and handles booking, rebooking, and waitlists where supported, and explains memberships and rewards — but never diagnoses, recommends a treatment, or promises results. Medical or uncertain questions escalate to your team, and it never collects patient information in a public setting.
Is everything custom-branded?
Yes — the website, the client app, the membership portal, galleries, and the concierge's voice all carry your brand. Your clients only ever see you.
What happens after I request a concept?
Nick personally reviews your brand, market, and website, then replies with a tailored concept direction for your practice's app and site and the highest-impact place to begin. Complimentary, no obligation.

Part of Eltherion's industry practices
What does Eltherion build for medical spas?
Eltherion builds custom-branded websites and client apps for med spas and aesthetic clinics — booking, rebooking, automated waitlists, a full membership and rewards program, retention and reactivation, and a 24/7 AI concierge. Everything is designed around how a practice runs and connects to the booking system you already use where supported. The AI answers approved questions and helps with booking and memberships, but never diagnoses conditions, recommends treatments, determines candidacy, or replaces a licensed provider — anything medical escalates to your team. Every platform is custom to the brand, not a template.
