Lambda books therapy sessions on WhatsApp, manages weekly recurring slots, and quietly handles the back-and-forth so you can focus on the work.
A client emails at 8 AM cancelling their 9 AM. By the time you see it, you've already arrived. A 50-minute slot lost — and that's €60-100 you can't recover today.
Twenty clients, each with their own weekly slot. Vacations, missed sessions, reschedules — your calendar is constantly shifting and you maintain it by hand.
A first-time inquiry deserves more care than "we have Wednesday at 3." Most chatbots get this wrong. You handle it manually, and it eats hours.
This is what your customers will see when they message you. Lambda replies in your tone, in their language.
Once a client commits to a slot, Lambda books their weekly session forward — 8, 12, 24 weeks. Vacations and changes are one-tap edits.
You write the welcome message. Lambda greets, qualifies briefly, books the intake session, and hands the rest to you.
No aggressive "confirm or lose your slot" — just a respectful nudge with the option to reschedule if needed.
Customers always get an answer, even at 2 AM on a Sunday.
Knows your hours, services, breaks. Books only what fits.
Each member has their own calendar, services, and availability.
EN, IT, DE, FR, ES, PT, NL, AR — auto-detected per customer.
24h before each appointment with one-tap confirm.
Your team can step in anytime, in one click.
No technical setup. No new phone number. You scan a QR code, we configure the rest.
Open WhatsApp Business on your phone, tap Linked Devices, scan. That's all the technical work you do.
Our team sets up your hours, services, staff, pricing, FAQs, and tone of voice — together with you in one 20-minute call.
From that moment, every WhatsApp message gets a reply within 10 seconds. You watch from the dashboard, jump in when you want.
Lambda doesn't give therapeutic advice. It handles scheduling and admin only. Everything substantive goes to you. You configure exactly what it does and doesn't reply to.
Yes. Lambda fetches their upcoming appointments and offers new slots — they choose, you approve (or auto-confirm, your call).
Lambda handles scheduling. Reimbursement codes stay in your existing billing system. Bookings can be exported to CSV monthly.
Set up in 30 minutes. Cancel before day 14 if it's not for you — no charge.
