The system
Four steps between an enquiry and a customer.
DIA covers the whole chain: capture, qualify, convert and follow up.
DIA understands the request
DIA asks your questions, works out what the customer needs and records the relevant details.
DIA turns it into an appointment
An appointment in your calendar, or a hand-over to the right colleague with the full context attached.
DIA leaves nobody behind
Missed calls and leads that go quiet are contacted again automatically.
Phone · WhatsApp · Website · Calendar · CRM · Automatic follow-up — in one system.

How it works
From intake to working system.
We build and manage DIA. You don't configure anything yourself.
Solutions
Built for businesses that depend on incoming calls.
Three common use cases. The building blocks are the same for every service business.
Restaurant · Harbour Table
PhoneLive
"A table for four this Friday evening?"
"I can offer 19:15 or 19:45. Which suits you best?"
Rule applied: dietary notes are added to the reservation; groups larger than six need approval from a team member.
Table booked · Fri 19:45
Vegetarian noted
Reservations are handled straight away, even during a busy service.
Salon · Maison Glow
WhatsAppLive
"Do you have space for balayage on Saturday?"
"New clients start with a consultation — 12:30 or 15:00?"
Rule applied: colour treatments start with a consultation and new clients are given extra time.
Consult booked · Sat 12:30
Extra time scheduled
Enquiries after closing time still turn into real appointments.
Real estate · North & Key
Website chatLive
"I am interested in the apartment on Harbour Street."
"Are you looking to buy or rent, and what is your budget?"
Rule applied: the budget is captured before a viewing and only available properties are offered.
Lead qualified · €425k
Viewing Sat 11:00
Agents mostly talk to leads who are already qualified.
Dental practices & clinics
Appointment requests and routing, with escalation rules for urgent cases and no medical advice.
Home services & trades
Take job requests with a safety check, address, urgency and appointment window while you are on the job.
Repair businesses
Handle faults, warranty questions and quote requests without a phone queue.
Gyms & coaching
Membership questions, trial sessions and follow-up with people who have not replied yet.
Beauty & wellness
Questions about treatments, availability and rescheduling without interrupting an appointment.
Local service providers
One receptionist for every call, so nothing depends on who happens to be free.
Example
What an implementation could look like.
Situation
Customers also call in the evening about breakdowns. No one picks up.
DIA automates
Phone and WhatsApp outside business hours — safety check, address and urgency go straight into the calendar.
Result
Out-of-hours breakdowns no longer go unanswered. The team starts the day with a planned route.
This is an example scenario to show how DIA works, not the result of an existing customer. We will show verified customer cases here once they exist.
What does one missed customer cost?
DIA only needs to recover a few missed opportunities.
Every business has a different customer value, so we do not use an artificial standard amount. What matters is how many calls, enquiries and appointments currently slip through unnoticed.
- Respond when a customer is ready to talk
- Automatically follow up missed calls and quiet leads
- Get more appointments from the enquiries you already receive

Pricing
More than an AI receptionist, without enterprise pricing.
Start by having your calls answered, then add qualification, appointments and automatic follow-up when you are ready. You only choose the modules you need.
Clear monthly limits · No surprises · Upgrade anytime
Professional setup from €299
- Business knowledge set up
- Call and follow-up flows configured
- Phone, calendar and system connections
- Realistic test conversations
- Monitored go-live
The final setup cost depends on the integrations and configuration required.
Prices exclude VAT where applicable. Additional call minutes are billed per minute at your plan rate. Setup is included with a yearly plan.
These modules are optional. Add them to a DIA plan or use them on their own — from messaging channels to the AI Lead Engine, which finds new customers instead of answering them.
A conversation is one active customer interaction within the same session.
External costs for WhatsApp, Meta, SMS and other providers may apply and are billed separately.

Questions before you start
Calls keep being answered. Extra minutes are billed per minute at your plan rate — €0.20 on Starter, €0.18 on Growth, €0.15 on Revenue and volume-based on Scale. You can upgrade at any time, and we agree alert thresholds before go-live.
Starter handles one call at a time, Growth handles three and Revenue handles five. Scale is set to your scope. During normal peaks, callers on Growth and above do not hear an engaged tone.
Yes. In most setups your existing number forwards to DIA — always, outside opening hours, or only when nobody picks up. Porting the number is possible in many countries but usually not needed.
Starter captures appointment requests for your team to confirm. From Growth upwards DIA checks live availability and writes appointments straight into Google or Microsoft Calendar.
Yes. DIA transfers calls by topic, urgency or on request. On messaging channels a colleague can take over the conversation with the full summary attached — just like in the demonstration.
Call and follow-up flow design, business knowledge, number and calendar connection, any CRM or workflow wiring, realistic test calls and a monitored launch. Setup starts from €299 one time and depends on the integrations required. It is included with a yearly plan.
No. External carrier costs, WhatsApp and Meta message costs, SMS costs and third-party platform costs may be billed separately. Expected usage costs are confirmed before go-live.
You define your ideal customer profile with us: sector, region, company size and type of service. The Lead Engine keeps finding matching companies from publicly available sources, reads their website, qualifies the opportunity with a score and delivers outreach-ready leads including the angle to open with. You keep final control over which messages actually go out.
Your number is used for the demonstration call you request, and we may contact you once afterwards about DIA. You can object to that and have your details deleted at any time. Implementations are designed with data minimisation, configurable retention and controlled access. DIA claims no GDPR certification; processing agreements are set per implementation.
