A WhatsApp AI agent that answers in under 5 seconds, built and tested for you

Most WhatsApp AI products hand you a builder and wish you luck. I design, train, connect and test the agent for you, and keep tuning it after launch.

Quick answer

A WhatsApp AI agent is an assistant that talks to your leads on WhatsApp, asks the questions your sales team would ask, answers questions about your products and passes qualified leads to a person with the full conversation. It runs on Meta’s official WhatsApp Business API and connects to your CRM.

What it does

Technical sales rep checking a message on a phone at the front office of a factory
  • Replies to every new lead in seconds, day or night
  • Asks your qualifying questions in a natural conversation, not a form
  • Answers technical and product questions from your own material
  • Books calls or meetings in your calendar
  • Hands the conversation to your team when a lead is ready or when it shouldn’t answer
  • Saves everything to the contact in your CRM

Results from a B2B manufacturer

I built WhatsApp agents for an industrial company that sells technical products with long sales cycles. Each agent was trained on two things: the qualification criteria the sales team uses, and the technical knowledge customers ask about.

  • Under 5sto the first reply
  • 70%of conversations handled without a human
  • 83%of the leads passed to sales arrived qualified

The agent isn’t there to replace the team. It’s there so the team only talks to leads worth talking to.

I also run one for my own business. It has handled more than 100 conversations and qualified about 47 leads.

Why not a do-it-yourself platform?

Platforms that build an agent from your website are a good fit if you have time to write the rules, test edge cases and fix it when it answers wrong. Most business owners don’t. Three steps usually get skipped: testing the agent against real questions, deciding when it hands over to a person, and reviewing its conversations after launch. Those steps are the core of my work.

When a WhatsApp AI agent makes sense also depends on how much of your sales conversation already happens there.

What it costs

All the ways I build AI agents

A medium-complexity WhatsApp agent usually costs around US$2,000 and takes about six weeks. WhatsApp messages and AI usage are billed by Meta and the AI provider; I estimate the monthly cost with you before launch.

FAQ

Frequently asked questions

  • Do I need a new WhatsApp number?

    No. You can keep your current WhatsApp Business number through coexistence, or use a new one.

  • Is it allowed by WhatsApp?

    Yes, through the official API, which is the only way I build. Unofficial tools can get your number blocked.

  • Can it answer in English and Spanish?

    Yes. Agents answer in the language the customer writes in.

  • What if a customer wants a human?

    The agent hands over right away, and your team sees the whole conversation.

  • Does it work without GoHighLevel?

    Yes. I’ve connected WhatsApp agents to Salesforce, HubSpot, Kajabi and systeme.io too.

  • How do I know it’s answering well?

    For the first 60 days, I review conversations and adjust the agent. After that, you can keep reviewing them in your CRM.

  • Will customers know it’s AI?

    Yes. The agent introduces itself as an assistant.
