We're picking five appointment-driven SMBs to get Business Zellbox free for 12 months, with the founder personally handling setup. Applications close September 18, 2026.

Zellbox is opening applications for a founder-run cohort of five appointment-driven SMBs. If selected, you get a Business Zellbox workspace ($1,188/year retail) free for 12 months plus hands-on onboarding delivered personally by the founder. Applications close September 18, 2026 at 23:59 UTC. Selected applicants will be contacted shortly after to book their setup call.

The offer, in specifics

Five businesses get:

  • A full Business Zellbox workspace, free for 12 months. That covers WhatsApp Business appointment reminders (default cadence 24h + 1h before every visit, offsets configurable), Google Calendar two-way sync, Gmail send-from-your-address integration, consents recorded on the customer file with audit trail, custom WhatsApp templates you own and edit, per-professional visit tagging, bulk CSV/XLSX customer import, and 12 customer-facing locales.
  • A 45-minute setup call with the founder. Google Calendar and WhatsApp Business get connected live on the call. Meta Embedded Signup for the WhatsApp Business number happens during the call — no back-and-forth over email, no ticket queue.
  • One custom WhatsApp template written for the business. You describe the subject and tone; the founder writes the template, submits it to Meta for approval, and it goes live inside 5 days.
  • CSV migration handled by us. Export your current customer list from whatever you use today — Excel, HubSpot, Callbell, AgendaPro, Doctolib, a WhatsApp Business phone, or paper — and email it over. We import and de-dupe. You do not touch the mapper.
  • Two follow-up calls: 30 minutes at week 2 (any friction), 30 minutes at week 6 (measure what moved and what didn’t).
  • Premium one-to-one support for the full 12 months. Priority WhatsApp + email channel with the Zellbox team. Ask us anything — configuration, template review, workflow design, integration questions. Same-day response Monday-Friday.

Who this fits

The offer is scoped to businesses where customers book, show up, and come back on a schedule. That covers dental and medical clinics, mental-health practices, aesthetic clinics, hair salons, barber shops, spas, physiotherapy and chiropractic studios, veterinary practices, home-services teams (plumbing, electrical, HVAC, cleaning), and business or real-estate coaches — plus any similar service business managing a customer schedule.

Team size 1-25 is the sweet spot for founder-run onboarding. You bring an existing customer list (spreadsheet, CRM, notebook, WhatsApp contacts — any format) so there is something to migrate.

Who this is not for

  • Consumer apps, marketplaces, or retail businesses with hundreds of thousands of contacts. Zellbox is optimised for teams managing a few hundred to a few thousand customers each.
  • WhatsApp broadcast or marketing-only tools. Zellbox is transactional and operational — the broadcast use case lives elsewhere.
  • Businesses that prefer a self-serve, no-touch trial. The 5-license cap exists specifically because each setup is run by hand.

Why 5 licenses, not 20

Founder-run onboarding does not scale past 5 per cohort. Each setup call, custom template, and week-2 / week-6 follow-up is handled personally — better to do 5 well than 20 poorly. In exchange for the license and the hands-on help, we ask you to share feedback about your experience so we keep improving. One testimonial after 60 days is appreciated but not required.

How to apply

Fill in the application form at zellbox.com/premium-launch. Ten minutes to complete. Real submissions get a personal reply.

The form asks a handful of details: your name and email, business name and type, country and team size, the CRM or tool you use today, and the biggest workflow pain point you are trying to solve — plus a checkbox agreeing to share feedback with the Zellbox team. WhatsApp number is optional but recommended so we can reach you faster if selected.

Applications close September 18, 2026, 23:59 UTC. Selected applicants will be contacted shortly after to book their setup call.

If you’re not sure whether Zellbox fits your workflow, the following resources answer specifics before the application:

  • The pricing page — what Business normally costs and what’s included at each tier.
  • WhatsApp reminders for dental practices — one worked example of the recall + reminder cadence for a dental workflow, which mirrors what you’d configure for salon rebookings, physio sessions, aesthetic follow-ups, or vet vaccinations.
  • The CASA Tier 2 announcement — evidence that the Google OAuth scopes Zellbox uses (Gmail send/modify, Calendar) are covered by an independent-lab security audit.

Frequently asked questions

How many licenses are you giving away?
Five. Zellbox is opening a founder-run cohort of exactly 5 appointment-driven SMBs, and the number is a hard cap because the setup calls are done personally — we do not have the capacity to run 10 or 20 setups by hand within one cohort window.
Who runs the setup calls?
Nacho Coll, founder of Zellbox, personally. The 45-minute setup call, the custom WhatsApp template writing, the CSV migration, and the follow-up calls at week 2 and week 6 are all handled by the founder — not a support agent, not a partner, not a bot.
What happens after the 12 free months?
You get a 30% renewal discount on the Business plan — no auto-charge, no card required to keep the workspace alive. If you prefer, you downgrade to the free Starter plan and keep your data with reduced quotas. There is no automatic renewal and no lock-in.
What Google permissions does Zellbox request?
Google Calendar (calendar, calendar.events) for two-way appointment sync, and Gmail (gmail.send, gmail.modify) so operators can send emails from their own Gmail address and replies route back to the customer record. Both scopes are covered by Zellbox's Google CASA Tier 2 certification and used under Google's Limited Use policy — never sold, never used for advertising, never accessed outside these workflows.
