WhatsApp AI agent development for businesses that live on WhatsApp

Your customers already message you on WhatsApp. A custom AI agent answers them in seconds, day or night: it understands the question, looks up the right information, asks the qualifying questions a salesperson would, and books the next step.

We build WhatsApp AI agents on the official WhatsApp Business Platform, connected to the tools you already use, with a person taking over whenever the conversation needs one.

Why TechDesk

Agents that stay up
Our AI layers run a provider chain with timeouts and fallbacks, the same pattern we built for our algo trading platform, so one model outage does not take your support line down.
Grounded answers only
The agent answers from your data and says so when it does not know, instead of inventing prices or promises.
Priced for real businesses
A focused WhatsApp agent starts at an indicative ₹75k in India or $2k worldwide. See the estimate tool for your case.

Questions about whatsapp ai agent development

Do I need the WhatsApp Business API?

Yes, for an AI agent on your business number. We set up the official WhatsApp Business Platform access with you and connect it to the agent.

Can the agent hand a chat to a person?

Yes. You decide the rules, for example pricing questions, complaints or high-value leads, and the chat moves to your team with the full history.

How long does a WhatsApp AI agent take to build?

A focused agent for one workflow usually takes 2 to 4 weeks, including testing on a separate number before launch.
