What's included

The problem with slow replies

Customers ask the same questions on your website and on WhatsApp, and they expect an answer in minutes. A team replying by hand can’t keep up outside working hours.

We build chatbots that answer from your own documents and FAQs, capture lead details, and hand the conversation to a person when it needs one.

  • Answers drawn from your content
  • Lead details saved to your CRM

What clients say

Pranav Nikumb

Owner, Crickstore
“Every bat we sell is unique, and tracking them as plain stock numbers caused constant confusion. Hexagon built a Telegram bot that records every bat with photos and AI-suggested specs. Our staff save time on every entry, and we always know exactly what we have. Hexagon really understood our problem. Highly recommended.”
  • AI Chatbots & WhatsApp Bots

Robert Miller

Marketing Manager
“Replying to messages on WhatsApp, Instagram and Messenger was taking up our team's whole day. Hexagon's bot now answers instantly across all three, even at night, and hands over the rest. We respond faster than ever without adding staff, which has saved us time and money. Highly recommend Hexagon.”
  • AI Chatbots & WhatsApp Bots

Ramesh Kumar

Customer Support Head
“Our support team kept answering the same questions all day. Hexagon built a WhatsApp bot that handles them in our own tone and only brings in a person when needed. Our support load has dropped a lot, and customers get answers instantly. It solved our biggest support problem. We highly recommend Hexagon.”
  • AI Chatbots & WhatsApp Bots

Cara Salazar

Founder
“Visitors were leaving our website without getting answers. Hexagon added a chatbot that answers from our own information and captures details when a visitor needs more help. We now get more and better enquiries without anyone watching the chat all day. Great value for money. Highly recommended.”

FAQ

Common questions

Everything you need to know before we start working together.

What do we need to run a WhatsApp chatbot?

An automated bot on a business number runs on Meta’s WhatsApp Business Platform. That needs a Meta Business account and a phone number registered to the platform. We help with the setup and connect the bot to your CRM and documents.

Does WhatsApp charge for chatbot messages?

Meta charges for template messages a business sends first (marketing, utility and authentication), at rates that vary by country. Replies to a customer inside the 24-hour window after their last message are free. Those fees are paid to Meta and are separate from the cost of building the bot.

Can a WhatsApp bot message customers first?

Only with a template message that Meta has approved, and only to people who have opted in to hear from you. Free-form replies are allowed once the customer has messaged you, within the 24-hour window.

Will the chatbot give wrong answers?

It answers from your own documents and FAQs rather than general knowledge. When the content doesn’t cover a question, it hands over to a person instead of guessing. We have built the same pattern for legal documents, where guessing is not acceptable.

Can one chatbot work on our website and WhatsApp?

Yes. One assistant, trained on the same content, can answer on your website and on WhatsApp, and save lead details from both to the same CRM.
