From first discovery to long-term client.
Someone finds you on Google, social, a referral, or an AI assistant — and your platform carries them from interest to consultation, booking, membership, rebooking, and referral. It works for people well beyond today's website visitors.
Book
Effortless mobile booking, easy rebooking, and 24/7 answers turn inquiries into consultations and treatments.
Belong
A full membership program plus rewards and loyalty that make coming back the default.
Return
Automated waitlists, reminders, and rebooking recover cancellations and keep treatment rooms and provider schedules full.
Refer
Referrals, gift cards, packages, and targeted promotions bring in new clients, encourage higher-value visits, and make it easier for loyal clients to share your practice.
Reach beyond your website: structured to improve how Google and AI systems understand and discover your practice, with referral links, campaign destinations, and push reactivation bringing people back.
No templates. Ten custom directions. Ten completely different experiences.
Ten fictional concepts across aesthetics, skin, wellness, and body — each leading with the surface that fits: a website, a client app, a membership, a portal, a dashboard, or a consultation.
Three featured experiences — tap one to explore it.

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 inquiries at any hour — and 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. Your concierge would be built and branded for your own practice — in your voice, on your approved services.

Your platform is designed to connect with the systems you already use, where supported — enhancing them rather than ripping them out.

Eltherion is led by Nick McCandless, a senior software developer with more than a decade building custom platforms, apps, and AI systems for companies across many industries.

Founder featured in
Featured for accomplishments helping businesses around the world — not an endorsement of this product.
Your brand, beautifully — including the work
Before-and-after galleries, treatment menus, and provider profiles presented as elegantly as your practice deserves — custom-branded across the website and app, never a generic template.
Fair questions, straight answers
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.
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.
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.
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.
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.
