AI agents · WhatsApp · Web

An AI salesperson that replies in seconds. Day or night.

I build AI agents that live on your WhatsApp and website. They answer questions from your real catalogue and prices, qualify the lead, take the order or book the call, and hand the chat to a human the second they’re out of their depth. In your voice, not a robot’s.

  • Businesses that sell through WhatsApp or chat
  • Teams answering the same 20 questions all day
  • Anyone losing late-night and weekend enquiries

Hi, is the rosemary & mint conditioner in stock? How much?
Hi! Yes, it’s in stock at KES 550. Want me to set up delivery? Just share your area.
Westlands. Can I pay on delivery?
You can, M-Pesa on delivery works. I’ve noted your order: 1 × conditioner to Westlands. Anything else? 😊

Sound familiar?

If any of this sounds like your business…

×A customer messages at 11pm. You reply at 9am. They already bought elsewhere.
×Your team spends half the day answering the same price and stock questions.
×You tried a chatbot once. It was a menu of buttons and customers hated it.
×You’re scared an AI will make things up and embarrass you.

Speed wins the sale. An agent that replies in seconds, from your real data, and knows when to call a human, is the cheapest salesperson you’ll ever hire.

What you get

What I actually deliver.

Real, working things. Not a report that sits in your inbox.

01

The agent

On WhatsApp (Business API or Evolution API) and/or your website, trained on your products, prices, policies and tone.

02

Live catalogue sync

Prices, stock, SKUs and images pulled from Odoo, WooCommerce, Shopify or a sheet, so answers are never out of date.

03

Qualification & tagging

Every conversation tagged by sales stage and source, so you know which chats turn into money.

04

Orders & bookings

Captures the order details or books straight into your calendar.

05

Human handover

Escalates to your team with the full context the moment it can’t answer, and alerts an admin.

06

Follow-up & reporting

Stalled chats get nudged on a schedule. You get a weekly view of conversations, orders and drop-offs.

How it works

From first call to live.

Clear steps, clear dates. You always know what I’m doing this week and why.

Week 1

Knowledge and rules

We gather your catalogue, FAQs and policies, and write down what the agent must never say or promise.

Week 2

Build and connect

Agent, catalogue sync, CRM and alerts wired together, tested against real past conversations.

Week 3

Soft launch

It drafts, your team approves. Once it’s getting things right, it goes live on its own.

Ongoing

Tune and report

I review conversations, fix weak answers and report on what the agent actually sold.

Why me

Why hire me instead of an agency?

01

One person, whole funnel

No handoffs between a designer, a developer, an SEO and an automation freelancer. I see how each piece affects the next.

02

I build, not just advise

You don’t get a slide deck of recommendations. You get working pages, tracking and automations, live.

03

Judged on money

Every piece of work is tied to a number that matters: leads, sales, booked calls. If it doesn’t move, we change course.

Ways to work together

Pick a starting point.

Fixed price, agreed before we start. You’ll get a straight number on the first call, not a range.

Questions

Before you ask…

Will it make things up?

It only answers from the knowledge and catalogue we give it, and it’s built to fail closed: if it isn’t sure, it hands over to a human instead of guessing.

Which languages can it handle?

English and Swahili out of the box, and most major languages. It can match how your customers actually write, including mixed Kenyan English.

What does it cost to run?

Usually a few dollars to a few tens of dollars a month in AI usage for an SME, plus WhatsApp costs. I’ll estimate it from your real message volume before we start.

Will customers know it’s AI?

That’s your call, and I recommend being upfront. Customers mostly care that they got a fast, correct answer.
