Stop losing customers
to missed calls.
We design, build, and run a custom AI phone system inside your business, then support it every month under a written SLA. It answers, qualifies, and books the calls you would otherwise miss.
The math behind a missed call.
Six short slides, about a minute. Use the arrows, or keep scrolling.
Before we sell anything, we do the math.
Every engagement starts with the numbers. Here is how our team looks at a service business, using an example.

Founder, LeadHunterOS
One engagement, four stages, no self-serve setup on your end.
Audit
We measure your call volume, how fast calls get answered, and where customers are lost. Free, no commitment.
Custom design
We design how the system answers, what it asks, and how it connects to your calendar and CRM.
Deployment
Built inside your own phone setup, not on a shared platform where you rent a seat.
Ongoing support
A monthly retainer under a written SLA covers monitoring, tuning, and changes as your call patterns evolve.
Built for businesses where the first call decides the deal.
Dental and medical clinics
New patients call when they decide to, often outside clinic hours. They book with whoever answers first, and a missed call is usually a booking that went to the next clinic on the list.
HVAC, plumbing, and electrical
A burst pipe or a failed AC unit doesn't wait for business hours. Whoever picks up first usually gets the job, and one voicemail is often enough for the caller to try the next number.
Other appointment-based businesses
If most of your revenue starts with an inbound call, the same math applies. The audit tells you whether it is worth solving for you.
Deployed on your stack, not ours.
Your phone setup, your control
The system is built inside your own phone setup. You own the numbers, the call logs, and the account. We don't sit between you and your provider.
Data isolation
Each deployment runs in its own isolated environment. Call data and transcripts are never pooled across clients.
Regional compliance
Architecture accounts for GDPR/RODO for EU clients and KVKK for Turkish clients from the start — not retrofitted after a request.
A small, hands-on team — not a support queue.
Rostyslav Zymyn
Founder, LeadHunterOS
LeadHunterOS is led by Rostyslav Zymyn, with a background in quantitative analysis and applied AI systems engineering, working alongside a small team of engineers who build and maintain every deployment. Whoever joins your audit call is someone who'll actually be involved in your build — not a sales layer sitting between you and the people doing the work.

Every engagement produces the same concrete deliverables.
Written audit findings
Your current response-time and lead-volume numbers, not estimates — delivered as a short document, not just talked through on a call.
Architecture diagram
How the agent connects to your telephony and CRM, reviewed with your team before anything is built.
A working prototype before you commit
You hear the agent handle a call scripted for your business before signing anything longer-term.
Defined SLA terms
Response times, monitoring, and change requests spelled out in the retainer — not left implicit.
Is this actually worth solving for your business? Run your own numbers.
Adjust these to roughly match your business. This is a directional estimate to help you decide whether it's worth a real audit — not a quote.
How this is calculated
Revenue at risk = after-hours leads × your close rate × a contact-decay discount (leads answered same-minute convert at your stated close rate; each additional hour of delay reduces that likelihood, based on general published response-time research — not data specific to your business). Your audit replaces this estimate with your actual numbers.Common questions
Is this a piece of software I install myself?
No. We design, build, and deploy the voice agent directly on your telephony stack. There's no dashboard for you to configure — changes go through your support retainer.
How long does deployment take?
Depends on integration complexity, particularly your CRM. Most deployments follow the audit with a defined build timeline scoped to your specific stack.
What happens on the audit call?
We look at your current lead volume, response times, and CRM setup, then tell you plainly whether this is worth solving for your business — including if the answer is no.
Do you work outside English-speaking markets?
Yes — deployments are built with regional compliance and local-language voice handling in mind, including EU and Turkish markets.
Find out if this is worth solving for you.
30 minutes. We'll tell you honestly whether the math works for your business.
