Example study

Randevu Plus Baku booking study

Randevu Plus is an online appointment booking app for private clinics in Baku, Azerbaijan. Patients find a clinic or a doctor by specialty and district, see real open slots, book in under a minute and get a reminder by SMS and WhatsApp. Clinics get a calendar, a patient list and automatic reminders, and pay us a flat monthly fee. Patients never pay.

A finished Cast study, read only. 16 interviews with AI users across 2 Ideal Customer Profiles (ICPs), run on October 19, 2026. Everyone quoted here is an AI user, synthesized to match an ICP. They are not real people.

What the study found

Look first at small single-specialty clinics only if price and double entry are solved, and start by proving reminders and easy sheet import with mid-size central clinics.

Both ICPs feel the pain of no-shows and missed calls or recalls, and reminders appeal to them. Most in each group want proof, a trial alongside current tools, and no double entry before paying monthly. Price is the sharper gate for small clinics, while data control and sheet import matter more for mid-size clinics.

Top findings

What each group said, ranked by how many AI users said it.

ICP A · 8 interviews

Mid-size central Baku clinics

Baku clinic owners feel the pain of no-shows and missed calls but want proof from similar clinics, data answers and easy migration before paying.

  1. 1. Reminders appeal strongly, but owners want proof before paying monthly5 of 8 AI usersNearly all feel the cost of empty slots and unanswered calls, and see reminders as a fit.
  2. 2. Owners want evidence from clinics like theirs, not sales claims5 of 8 AI usersMany said they hold back on change until peers of similar size have used it for a while.
  3. 3. Patient data control is a gate before any trial4 of 8 AI usersSeveral owners would not put patient records into an outside system without clear answers on storage and access.

ICP B · 8 interviews

Dental and single-specialty clinics

Small clinic owners feel the pain of no-shows and missed recalls, but price, double entry and proof hold them back.

  1. 1. Monthly price is the main gate, judged against empty-chair losses8 of 8 AI usersNearly all of these owners named the fee first.
  2. 2. No-shows and missed recalls hurt, and reminders appeal in principle7 of 8 AI usersOwners described recent empty chairs and forgotten recalls driven by paper diaries, sheets and memory.
  3. 3. Keeping the calendar in the app raises double-entry and trust worries6 of 8 AI usersOwners fear extra work for stretched receptionists and a second diary running alongside the app.

The Casting Agent read the brief, proposed the ICPs and wrote one question list. Each AI user then answered every question in its own interview and the findings were written from those transcripts. AI users role-play a defined customer from what that customer would plausibly know and feel; they do not look anything up.
