Adam Etherz
Founder, VoxStack

I built VoxStack because the problem is obvious and the fix is now technically straightforward. Local service businesses run on phone calls. Most of them are missing 30–40% of their inbound calls because nobody's available after 6pm or on weekends. That's fixable with an AI voice agent.

We work with a limited number of clients at a time so the work gets done right. If you're here, there's a good chance we've already built a demo for your exact vertical. Book a call and I'll show you.

FAQ

Common Questions


The agent sounds natural — not robotic, not obviously AI. It introduces itself as your receptionist by your business name, uses conversational language, handles interruptions, and knows when to escalate to a human. We use Retell AI, which is purpose-built for voice. You can listen to a live demo on our call before committing.
We configure a seamless handoff. If the caller asks for a human, uses language outside the script, or the AI isn't confident in an answer, it takes a message and flags it for your team — typically via SMS or email within seconds. You set the rules; we configure the behavior.
No. We integrate with your existing business number using a call-forwarding setup. Your number stays the same, your callers don't notice anything different except that someone actually answers.
We've worked with ServiceTitan, HubSpot, Go High Level, Jobber, Calendly, and basic Google Calendar setups. If you use something else, ask us on the call — most booking systems have a connection path we can build.
3-month minimum after the one-time setup fee, then month-to-month. We ask for 3 months because that's how long it takes to optimize ad performance and tune the voice agent to your call patterns. After that, you cancel with 30 days notice — no penalties, and we hand off your systems cleanly.
