Why I Built This
The real story behind Ottster
I'm Ott. The name Ottster goes back to my college days — I picked up the nickname working part-time at a grocery store, and it's been with me ever since. It stuck because it fit: always moving, always working, never stopping. That's exactly what I built this to do for your business. I built it after watching contractors lose thousands in revenue every single month because they couldn't answer calls while on job sites.
The pattern was always the same: A customer calls. You're 30 feet up a ladder or elbow-deep in work. The call goes to voicemail. They call the next name on Google. By the time you call back, they've already hired someone else.
"I lose 5 to 8 leads every week because I can't answer my phone. That's $8,000 to $12,000 a month just walking away."
— Real contractor feedback
That's what I set out to build: An AI receptionist that answers every call instantly, qualifies every lead, and books appointments automatically — 24/7, even while you're on the job.
It's built on Claude AI (the most human-like AI available) + OpenClaw (the framework OpenAI hired to build autonomous agents) + 20 hours of custom training on YOUR specific business. Your customers won't know they're talking to AI.

How We Deploy Your Agent
Every agent we build follows the same proven process — from first contact to completed action, fully automated.
Customer Reaches Out
Works via phone, SMS, WhatsApp, or web chatA prospect calls, texts, chats, or fills out a form — any time of day or night. Instead of hitting voicemail, a dead form, or waiting hours for a reply, your AI agent responds immediately.
AI Responds in Seconds
Average response time: under 60 secondsYour agent — trained on your business, services, and pricing — responds professionally and naturally. It handles the conversation the way your best employee would, not like a generic bot.
Lead Gets Qualified
Custom qualification criteria for your businessThe AI asks the right questions to understand the customer's need, urgency, and location. Only qualified, serious leads move forward — saving you time on tire-kickers.
Action Completed
Configured for your specific workflowThe agent completes the intended action — booking an appointment, qualifying a lead, answering a support question, or triggering a follow-up. All in the same conversation. Zero manual work from you.
You Get Notified
Instant alerts + automatic lead loggingThe moment your agent completes an action, you receive an instant notification with the full details. Every interaction is logged automatically — no manual data entry, no leads falling through the cracks.
Setup takes one business day.
We handle the training, configuration, and go-live. You just start capturing leads.
Built for Small Business Owners Who Are Always Busy

Answer Every Call, Every Time

AI answering customer calls
Automatic appointment booking
Appointments Book Themselves
Customer calls: "I need an estimate." AI immediately checks your Google Calendar, shows 3 available times, books their preferred slot, and sends them a Google Calendar invite with your address and contact info. Zero manual work from you. Appointment is already in your calendar before you finish the current job.
- Checks YOUR Google Calendar in real-time
- Books appointments directly to your schedule
- Customer gets a Google Calendar invite automatically

Trained on Your Business
We spend 20 hours training the AI on YOUR specific business: your pricing, service areas, emergency rates, response times, warranty info, payment methods — everything. When a customer asks "How much for an emergency call on Sunday?" the AI answers with your exact rates and availability. It sounds like your best employee, not a robot.
- Answers questions about pricing (emergency rates, standard rates, add-ons)
- Knows your service areas and response times
- Sounds like your business, not a generic chatbot
- Improves over time with real conversations

How One HVAC Contractor Reclaimed Lost Revenue
From 5 missed calls per week to zero. Here's what changed.
Mike's HVAC Services
Residential & Commercial • Denver, CO
The Problem
- •5–8 missed calls per week because Mike and his team were on job sites

The Solution
Mike set up an AI receptionist trained on his HVAC services, pricing, and scheduling. It answers his calls 24/7, qualifies leads, and books appointments directly into his calendar.
