## Executive Summary

**AVO** is a multi-tenant SaaS platform that provides small businesses with their own AI-powered phone receptionist. Using cutting-edge voice AI technology from Google Gemini, each paying customer receives a dedicated phone number with an intelligent agent that answers calls 24/7, sends real-time SMS summaries to business owners, and books appointments directly to Google Calendar.

**Live Product:** [avo.run](https://avo.run)  
**Stage:** MVP Complete, Pre-Revenue

## The Problem

Small businesses lose significant revenue from missed calls:

- **40-60% of calls go unanswered** when owners are busy working
- **Each missed call = $200-500** in potential lost revenue (service calls, bookings)
- **Traditional solutions are expensive:** Full-time receptionist costs $35,000+/year
- **Existing AI solutions** require technical setup, monthly contracts, or complex integrations

**Target customers:** Plumbers, HVAC contractors, salons, medical offices, legal practices, real estate agents, and any small business that relies on phone inquiries.

---

## The Solution

AVO gives every small business an AI employee that:

1. **Answers every call** - 24/7/365, no breaks, no sick days
2. **Sounds human** - Natural conversation powered by Google Gemini native audio
3. **Takes action** - Books appointments, answers FAQs, captures lead info
4. **Alerts owners** - Instant SMS with call summary and key details
5. **Integrates seamlessly** - Google Calendar for scheduling

### How It Works (2-Minute Setup)

1. Sign up with Google (no passwords)
2. Configure your AI agent (business name, services, voice)
3. Buy credits (starting at $9.99)
4. Get your dedicated phone number (instant provisioning)
5. Go live - forward your business line or advertise the number
