If you've ever called a plumber at 10 PM and gotten voicemail, you already understand the problem we're solving. That call doesn't come back later. It goes to the next number on the list. ZeroCallix is an AI receptionist for US service businesses (HVAC, plumbing, electrical, roofing, law firms). It answers every call 24/7, qualifies the caller, checks the real calendar, and books the appointment on the spot. What we cared about building: • Sub-500ms responses, so it doesn't feel like a chatbot • Real interruption handling — cut it off and it actually stops and listens • Books jobs instead of promising callbacks • Fully managed. We set up the whole thing. The client never sees a prompt or an API key. Honest limitations while we're here: US-only for now, no HIPAA tier yet, and we onboard clients by hand rather than self-serve. All deliberate at this stage. The demo line is the fastest way to form an opinion — call it and try to break it.
