Real businesses,
real calls handled
Australian businesses using VerticalAI to handle inbound calls, reduce hold times, and free up their teams for work that matters.
We estimate that VerticalAI will manage approximately 40% of our inbound calls. We went from idea to a working agent in a day, and continue to work alongside them to further enhance our operations.
Phil George
Founder, EarnOS
Our care coordinators used to spend hours on routine Home Care Package enquiries. Now the agent handles them and hands off to a person when it needs to. The team focuses on actual care instead of answering the same questions.
PlanCare Team
Healthcare-at-Home Provider
We needed to prove voice AI could handle our member services before committing to a full build. VerticalAI gave us a working prototype on a real phone number in under an hour. The stakeholder demo sold the project.

LikeHighlights
Sub-second voice AI, built for real calls
Deepgram Flux STT, Claude Haiku, and Cartesia Sonic 3 TTS — all routed through Sydney infrastructure for consistent low latency
~800ms Response Time
Deepgram Flux semantic end-of-turn plus Claude Haiku plus Cartesia AU endpoint. The agent responds before the pause feels unnatural.
Cartesia Sonic 3 Voices
100+ voices with Australian accent options. Synthesised from our Sydney TTS endpoint — 8ms to the server. Sounds right for the market.
Semantic Turn Detection
Deepgram Flux detects when you're done talking based on meaning, not silence. No awkward 300ms pause waiting for a timer to expire.
Highlights
Describe what you want. The platform builds it.
No code, no YAML, no configuration files. Build in the visual editor or describe your flow in plain English. Live in under an hour.
Visual Flow Builder
Every step in the conversation is a node. Drag, connect, edit. A call centre manager can read it. A developer can extend it. Describe what you want in plain English and the AI builds the flow.
Tool Calls During Conversations
Add HTTP tool call nodes to your flow. The agent can look up accounts, book appointments, check order status, or hit any REST API — mid-conversation, in real time.
Knowledge Base Search
Upload PDFs, paste URLs, or type text. The agent searches your knowledge base during calls and answers from your content. Powered by pgvector embeddings.
Choose Your Model
Claude Haiku for speed. Sonnet for accuracy. Opus for complex reasoning. Llama Scout via Groq for the fastest response times. Pick the right model for each use case.
Highlights
Test before you ship. Improve after you launch.
Chat and voice testing built into the flow editor. Make a change, run a test, hear the difference in seconds. Every test session uses the same pipeline as a real call.
Every call is recorded with a full transcript, state transitions, and per-turn timing breakdown — STT latency, LLM time-to-first-token, and TTS delivery. See exactly where time is spent.
The analyzer reviews completed conversations, identifies where the flow broke down, and suggests specific patches. Review the suggestions, apply with one click, and redeploy.
Integrations
One flow,
every channel.
Phone
Inbound calls via Australian Twilio numbers. SIP trunking to Daily.co WebRTC. Real phone conversations at ~800ms response time.
Web Chat
Same flow, no phone needed. Shareable demo links with voice and text chat built in. Send a link, get feedback in minutes.
Shareable Links
Publish your flow and get a link anyone can use. No login required on their end. The fastest way to demo voice AI to a stakeholder.
WebSocket API
Connect your own frontend via WebSocket. The same FlowEngine that powers voice calls runs your custom integration.
Highlights
Australian numbers. Australian infrastructure.
Purchase local Australian numbers directly from the platform and assign them to your flows. Callers see a real local number, not a US toll-free.
Connect your existing telephony infrastructure via SIP trunking. Twilio handles the PSTN side, Daily.co handles the WebRTC transport. Both route through Sydney.
When the agent reaches the edge of what it can handle, it transfers the call to a real person with full context. Clean handoff, no repeated information.
Calls are processed on Fly.io Sydney. TTS runs on Cartesia’s AU endpoint. Data is stored on Supabase ap-southeast-2. WebRTC media stays in Daily.co’s Sydney region.

FAQ
Common Questions
All data at rest is stored in Sydney on Supabase (AWS ap-southeast-2). Voice agent compute runs on Fly.io Sydney. WebRTC media stays in Daily.co’s Sydney region. TTS is synthesised from Cartesia’s AU endpoint. LLM and STT calls go to US-based APIs but are transient — no data is stored by those providers.
No. The visual flow builder lets you design conversation flows by dragging and connecting nodes. You can also describe what you want in plain English and the AI builder generates the full flow for you. No code, no servers, no configuration files.
Under an hour. Sign up, build a flow (or start from a template), test it with the built-in chat and voice tester, publish, and assign an Australian phone number. Most users have a working callable demo within their first session.
Every account starts with $20 in free credits. Usage is charged per interaction — no monthly subscription. When credits run low, top up. Phone numbers are purchased separately. Pricing is transparent: Deepgram STT, Claude LLM tokens, Cartesia TTS characters, and Twilio telephony are billed at cost plus a small platform fee.
Claude Haiku 4.5 is the default for voice agents — fast and cost-effective. Claude Sonnet 4.6 and Opus 4.6 are available for flows that need stronger reasoning. Llama Scout via Groq is the fastest option for simple flows. Deepgram Nova-3 Flux handles speech-to-text with semantic end-of-turn detection. Cartesia Sonic 3 handles text-to-speech with 100+ voice options.
