Questions and Answers

What makes your product unique?

Postbot's answer

Instant Setup from Your Website โ€“ No Tech Needed 100% Call Coverageโ€”Even Nights & Weekends Natural Voice, Not Just Menus or Chat Scripts Pay-as-You-Go Pricing

Why should a person choose your product over its competitors?

Postbot's answer

Set It Up in Minutes, Not Days Unlike competitors that require manual setup, API integrations, or calendar syncing, Postbot scrapes your website to build a custom knowledge base automatically. โ†’ Youโ€™re live in minutes, even with zero tech skills.

๐Ÿ—ฃ๏ธ 2. Human-Like Voice That Builds Trust Most AI tools still sound robotic or follow rigid phone trees. Postbot uses natural-sounding AI voices that handle open-ended conversations like a real person. โ†’ Your customers feel heard, not herded through a menu.

๐Ÿ“… 3. Appointment Booking Without the Tech Headache Many competitors require full calendar integration, which can break or require upkeep. Postbot just texts your booking linkโ€”clean, simple, and flexible. โ†’ Fewer no-shows, less friction, and no added tools to manage.

๐Ÿ’ธ 4. Pay-as-You-Go Pricing With No Hidden Costs

How would you describe your primary audience?

Postbot's answer

Micro-businesses (1โ€“5 people): solo-preneurs, contractors, therapists, stylists, tutors, personal trainers

Small businesses (5โ€“50 people): law firms, dental clinics, med spas, home service pros, real estate teams, small hotels

Field-based and appointment-based businesses: where availability is limited and booking speed matters

Owners who wear multiple hats: and need a tool that just works without them needing to babysit it

What They Need: A reliable, always-on receptionist without the cost or complexity of hiring

A tool that requires zero technical setup and works out-of-the-box

A way to capture leads after hours, during lunch, or while theyโ€™re serving other customers

A pricing model thatโ€™s flexible, transparent, and doesnโ€™t punish low volume

What's the story behind your product?

Postbot's answer

Postbot was born from a simple, painful truth: small business owners are missing too many opportunitiesโ€”just because they canโ€™t pick up the phone.

The founding team had spent years building voice automation for big companies, helping them reduce support costs and improve customer experience. But what they kept noticing was this: the little guysโ€”the therapists, stylists, plumbers, and attorneysโ€”were getting crushed by missed calls, bad phone trees, and expensive virtual receptionist services.

Which are the primary technologies used for building your product?

Postbot's answer

Voice AI & Natural Language Processing (NLP) Powered by large language models (LLMs) and speech-to-text / text-to-speech systems Enables natural, human-like conversations and intelligent FAQ handling Supports multi-language interactions (e.g. English, Spanish, French, German)

Telephony Infrastructure Built on top of scalable cloud communications platforms like Twilio or Plivo Handles call routing, voicemail fallback, number provisioning, and SMS delivery

Web Scraping & Knowledge Extraction Automated parsing of business websites using AI-enhanced scraping tools Converts content into structured, queryable formats for dynamic response generation

Who are some of the biggest customers of your product?

Postbot's answer

Small Businesses
