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 opportunities—just because they can’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 guys—the therapists, stylists, plumbers, and attorneys—were getting crushed by missed calls, bad phone trees, and expensive virtual receptionist services.

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
