About
Australian businesses deserve voice AI that runs here.
What we believe
Most voice AI platforms are built in the US, for the US. Australian businesses end up with their customer data on foreign servers, USD invoices, and support that’s asleep during AEST business hours. We built VerticalAI because that’s not good enough.
How we build
Every component runs from Sydney. Supabase for data storage. Fly.io for compute. Cartesia’s AU endpoint for text-to-speech. Daily.co’s Sydney region for WebRTC. We chose each provider for latency and data residency, not just features.
Who it’s for
Call centre managers who want to automate without writing code. Business owners who can’t staff phones 24/7. Consultants who need a working demo by Friday. Enterprise teams who need to prove the concept before the board approves the budget.
