The AI Receptionist that books jobs while you're on the job.
Underdog Engine answers calls, replies to messages, books appointments straight into your calendar, and sends reminders — 24 hours a day, in your business's voice.
// THE COST OF MISSED CALLS
You're losing money every time the phone rings while you're working.
If you're an HVAC tech under a furnace, a plumber under a sink, a roofer on a ladder, a salon owner with a client in the chair — you can't pick up. Your voicemail says "leave a message" and 80% of callers just hang up and call the next business on the list.
The 20% who do leave a message? You call them back hours later, and half of those have already booked elsewhere. That's the cost of every missed call: a lost customer, a lost job, and a lost lifetime of repeat work.
// THE SOLUTION
Meet the AI receptionist your business actually deserves.
// HOW IT WORKS
Every Call. Handled.
Whether your team picks up or not — no lead ever falls through the cracks again.
A customer calls your business number
Same number. Nothing changes for your customer.
Your team answers
Business as usual. Nothing changes.
No one answers
Your AI receptionist picks up instantly.
AI gathers details and schedules the job
Asks the right questions. Books directly into your calendar. Sends a confirmation text to the customer.
You wake up with new jobs already booked
No callbacks. No missed leads. No manual work.
Every missed call becomes a captured job opportunity.
// WHY UNDERDOG ENGINE
Why businesses choose Underdog Engine.
Natural conversations, not phone-tree menus

Real human handoff when it matters
If a caller asks for you, we route them to you. The AI knows when a human needs to take it.
Built for Canadian trades & home services
Tuned for the way Canadian service businesses take calls — local time zones, the questions your customers actually ask, and pricing that scales with your call volume.
// INDUSTRIES
Built for the businesses that can't afford to miss a call.
// LOCATIONS
Available wherever your business answers the phone.
