Turn a URL into a live voice agent before your prospect loses interest.
The backend for a voice AI agency. Paste a prospect's website and get back a live, callable, on-brand demo - knowledge base, voice agent, and quality check included - in minutes, not an afternoon.
A real line answered by a real agent. Hear it, then grab your spot below.
Illustrative · the real pipeline, example businesses
Every voice AI agency hits the same ceiling: building the proof.
Hours per prospect
Writing a system prompt, wiring a knowledge base, testing edge cases, standing up a landing page - all before you know if the deal even closes.
Trust dies in the gap
Nobody believes voice AI is good until they hear it answer for their own business. The longer it takes to get them a live line, the colder the lead gets.
Ops breaks past client five
Every new client is another dashboard, another number, another brand to keep straight by hand. What works for two clients doesn't work for twenty.
Paste a URL. Walk away with a live agent.
Three moves, one pipeline. You do the first; it does the rest.
Point it at their site
The page gets read automatically and turned into a working knowledge base - real services, hours, and answers, not a generic script.
It builds and stress-tests the agent
A real conversational voice agent goes live behind the scenes, then runs a scripted quality pass before anything reaches a prospect.
You get a link to send
A shareable, on-brand demo page with a real phone number and a browser call button - ready the same hour you found the lead.
Not a pitch deck. A working phone line with their name on it.
Every demo becomes a live, callable agent a prospect can test on their own phone, on their own terms. Once a client goes live, every real call after that turns into a structured summary - proof your agency is delivering, not just selling.
An agency backend, minus the parts you'd have to build yourself.
Real knowledge base, not a script
Built from the business's own site content across 10+ industries, not a template with a swapped logo.
Quality-checked before it's shown
A scripted stress-test pass runs on every agent before it ever reaches a prospect.
White-label, actually white-label
Your logo, your accent color, your booking link. Clients never see our name anywhere in the flow.
A branded portal for every client
Hand each client a read-only call log under your brand - not a support ticket, an actual link.
One dashboard, every client
Every workspace, agent, and number in one place instead of scattered across tools.
Bring your own voice account
Plug your own ElevenLabs key into a workspace and keep your own usage, billing, and margin.
Two starting points. Same tool.
Starting a voice AI agency
You know the category is real, but building your first demos by hand is slow, and every hour on setup is an hour not spent talking to prospects. Skip the manual build and show up with live proof from call one.
Scaling one you already run
You're past your first few clients, and the manual process that got you here won't get you to fifty. Standardize how every demo gets built and every client gets managed, under your own brand.

Plug in your own numbers. Illustrative math, not a guarantee.
We run our own voice AI agency on this exact stack.
Demo Factory isn't a side project from people who've never sold this. Apilon AI builds and sells AI voice receptionists to real businesses, and this is the internal tool we built to stop losing hours to manual demo-building. We're opening it up because the bottleneck isn't unique to us.
Before you sign up
What does the beta cost?+
Nothing. The open beta is free and signup never asks for a card. Paid plans come later, and nothing switches on silently - you would pick a plan yourself before paying a dollar.
Why wouldn't I just build this on Vapi or Synthflow myself?+
You can - and then you're the one wiring the scraper, the knowledge base, the prompt, the quality checks, the client-facing demo page, and the call portal, for every single prospect. Demo Factory is that whole pipeline already built, so you spend your time selling instead of rebuilding plumbing per lead.
Is the voice good enough to put in front of a paying prospect?+
Don't take our word for it - call the live line at the top of this page and judge it yourself. It runs on ElevenLabs conversational AI, and every agent is stress-tested before it's shown to anyone.
Do I need to be technical to run this?+
No. You paste a URL and the pipeline does the build. If you want to hand-tune an agent's prompt you can, but nothing about the core flow needs code.
Will my clients ever see your branding?+
No. Every workspace sets its own logo, accent color, and booking link, and both the client-facing demo page and the call portal use it - not ours. Bring your own ElevenLabs key and your usage is yours too.
Who controls the client data and call logs?+
Each workspace is isolated - a client only ever sees their own calls through their portal link, and one client can never see another's. The relationship and the data stay yours.
Does this replace my client relationships?+
No. Demo Factory builds the proof and runs the ops backend. The sales conversation, the pricing, and the client relationship stay entirely yours.
What if a client cancels, or I want to leave?+
No long lock-in. Deactivate a client's workspace when they churn; leave whenever you want. We'd rather keep you because it works than trap you in a contract.
Your next demo shouldn't take an afternoon.
The beta is free and we invite in small batches. Grab a spot now - you build your first demo the day your invite lands.
