AI voice agents
your leads love talking to.
Our voice agents call, qualify and book your leads in seconds. When a call is not answered, the same AI follows up by text or WhatsApp until the lead is booked, and it runs as chat on your website too. One intelligence, every channel. You only pay when we deliver.

I'm not an AI fan, but you have changed my mind.
Hear what natural AI voice actually sounds like.
Stellar's voice agents sound natural because we invest in the details that matter most: warm pacing, natural hesitation, the ability to handle interruptions without losing the conversation, and the focus to stay on track toward one goal. Figuring out if this lead is real and getting them booked in with you.
Before our first client sent a single real lead through the system, he tested the voice himself. He called in, asked the kind of curveball questions a real customer would ask, and reacted in the moment. His verdict:
"That's just so unreal, well done!"Denes Aldott, EasyStart Homes
That client, Denes Aldott from EasyStart Homes, has now been live for over 6 months. His leads do not realise they are talking to AI.
This is also why we are confident enough to tie our pricing to results. When the AI sounds this natural, leads engage. When leads engage, they qualify. When they qualify, they book. We built a system that works, and we priced it so you only pay when it does.
One brain. Every channel.
We build one AI agent, one prompt and one strategy for your goal, then run it everywhere. Whether your lead talks to it, texts it or messages it on WhatsApp, it is the same intelligence driving the same conversation toward the same booking.
AI Voice
Calls new leads in seconds, sounds genuinely human, qualifies against your criteria and books the meeting on the call.
AI Text
When a call goes unanswered, the same agent follows up by SMS and holds a real two-way conversation until the lead is qualified and booked.
AI WhatsApp
For markets that live on WhatsApp. The system automatically chooses text or WhatsApp based on the lead's country.
The same agent can also run as a chat widget on your website, feeding the exact same qualify and book flow.
Voice stays the closer. When a lead re-engages by message, the agent loops back to a call. No disconnected chatbot that forgets what the caller already said. No separate SMS tool with its own clunky script. Consistent tone, consistent qualifying logic, consistent outcome.
Hear a genuine call placed by our AI.
This is an outbound call our system made on behalf of EasyStart Homes. Edited for length and privacy. Not a script. Not a demo. A real call.

What sets us apart
Reliability is the product.
Anyone can demo an AI agent. Making one dependable enough to represent your business on every call is the hard part, and it is exactly where we have invested.
Best-in-class AI, orchestrated in-house
We build on the strongest AI available today: Google Gemini, OpenAI's ChatGPT models and ElevenLabs voices. Our own platform orchestrates them into one dependable agent, and when a better model ships, your agent gets it.
A testing and simulation system like no other
We built our own state-of-the-art testing and simulation platform because nothing off the shelf met our bar for reliability. Every agent runs hundreds of simulated conversations, objections, edge cases and guardrail probes before it ever speaks to a real lead.
Every call makes it better
Every conversation is recorded, transcribed and scored, and we use it to keep improving your agent over time. Reliability is not a launch-day feature. It compounds.
Built end to end, in-house
Our platform is our own. When something needs to be better, we change it that day, not when a vendor's roadmap allows. That is how the agents stay fast, accurate and dependable at scale.
