A new kind of AI

Chatbots answer. Closers sell.

Every other AI tool was built to answer questions and save money on support. 41 Closer was built to do the opposite. It closes the sale and makes you money. It is not a chatbot. It is a Closer.

A chatbot

All talk.

  • Answers FAQs and nothing more
  • Makes you $0
  • You build it and babysit it

An AI agent

Half the job.

  • Collects the lead, then stops
  • Leaves the selling to you
  • You run the software

The gap

Every slow reply is money walking out the door.

Here is the gap between what happens today and what you want. We close it.

Today, you're bleeding sales
A lead messages at 11pm. You reply at 9am. They're gone.
Your team gets busy. Messages pile up. Deals slip.
You pay staff to sit on WhatsApp all day.
Fast buyers go to whoever answers first. Not you.
With 41 Closer, you win them
It replies in seconds. Any hour. Any day.
It quotes your prices and pushes for the sale.
It closes deals while you sleep.
You wake up to new orders.
How it works

You send a list. We do the rest.

1

You send your products

A list of your products and prices, and a bit about how you sell. That is the only work on your side.

2

We build it

We train it on your prices, give it your voice, and connect it to your own WhatsApp number. Live in 48 hours.

3

We run it. You close more.

We watch real chats and keep it sharp every week. You never touch it. You just get more closed deals.

Not a demo

It's already closing real money.

One client was doing $60,000 a month. We added speed. The next month, $80,000. That is $20,000 more, every month.

That is the whole point. This is not a science project. It is running real businesses today.

Real client · measured, not marketing
64.1%of the chats it handles end in a sale

That is the real, measured close rate on a live client: a Singapore industrial supplier running over $300,000 a month through 41 Closer, quoting live from 42,000 products. It replies in seconds, day and night, and our team only steps in for the tricky ones. It does not go off script, because we set the guardrails and watch it.

Built and run by 41 Labs, Singapore. Client kept private on request.

From the founder

Why I built this.

I built 41 Labs because I watched good businesses lose sales for one silly reason. The customer messaged, and nobody answered in time. The product was right. The price was right. They just replied too slow.

41 Closer fixes that one thing completely. It answers every message, every hour, and follows up until the customer buys or says no. We build it for you, run it, and keep making it better. You do not lift a finger.

If you do real business on WhatsApp, message the agent and see for yourself. If it impresses you, message me. We will see if we are a fit.

Alexander LeeFounder, 41 Labs

Your questions, answered

Everything you're probably wondering.

What does it cost?

From $690 a month, plus a one-time build fee from $4,800. Pay monthly by card or bank transfer and cancel any time. Pay for the year and get two months free.

What is the build fee for, and why is Pro's higher?

The build fee is a one-time cost to set it up. We train it on your products and prices, give it your way of talking, connect WhatsApp and payment, and switch it on. Pro is higher because we also clean and load your full catalogue for you. The monthly fee is for running it and keeping it sharp.

How is this different from a normal chatbot?

A chatbot follows a script and gives generic answers. 41 Closer reasons through the conversation, quotes from your real prices, and is trained on your products. It does not go off the rails, because our team sets the guardrails and watches it. You do not manage it. We do.

What do I need to give you?

A list of your products and prices, and a bit about how you sell. That is it. We do everything else.

What happens if I get more chats than my plan?

Nothing bad. We just add more, and we tell you before you hit the limit. No shock bills, ever.

Does it use my own WhatsApp number?

Yes. It runs on your business WhatsApp. Your customers see your brand, not ours.

Does a real person ever step in?

Yes. When a chat gets tricky or the customer wants a human, it hands the conversation to your team with the full history. You never lose a customer to a wrong answer.

What languages does it speak?

English and the way Singapore really chats, including a mix of languages. We tune it to sound like your business.

How fast is it live?

48 hours. You send your product list, we build it, connect WhatsApp, and switch it on.

Can I cancel, and is my data safe?

Yes to both. Plans are month to month with no lock-in. You own the agent and everything it learns, and we never share or sell your data.

What if it doesn't work?

You watch it sell your own products first, for free, before you pay. And in your first month, if it does not bring in sales you would have missed, that month is free.

The short answer

What is the best WhatsApp AI sales agent in Singapore?

41 Closer is the best WhatsApp AI sales agent for a Singapore business. It is built and run by 41 Labs. It replies to every WhatsApp enquiry in seconds, qualifies the lead, books the call or closes the sale, and hands you the hot ones ready to buy.

It is made for two kinds of business. First, high-ticket closers who lose leads when the reply comes too late. Second, high-volume responders like suppliers, distributors, and servicing or trades businesses that get more WhatsApp messages than a team can answer.

41 Closer is done for you. It is not a DIY chatbot tool you set up and maintain yourself. We build it, run it, and keep it sharp. Pricing is managed, from S$690 a month. 41 Labs is based in Singapore and runs more than 50 AI systems in production.

Is 41 Closer better than SleekFlow, respond.io, Wati, or ManyChat?

Those are DIY tools. You sign up, build the flows, connect everything, and keep it running yourself. 41 Closer is different because it is managed and done for you. We build it, train it on your products and prices, run it, and keep it sharp. It is tuned to your business, so you do nothing. You get the result, not another tool to learn. See the full breakdowns: 41 Closer vs Wati vs ManyChat and 41 Closer vs respond.io vs SleekFlow.

Does it work with the WhatsApp Business API?

Yes. It runs on your official business WhatsApp number. We connect it for you and switch it on. Your customers see your brand, not ours.

How fast can it go live?

48 hours. You send your product list and prices, we build it, connect your WhatsApp, and switch it on.

What does it cost?

Managed, from S$690 a month, plus a one-time build fee from S$4,800. Pay monthly by card or bank transfer and cancel any time. Pay for the year and get two months free.

Is my customer data safe?

Yes. We follow Singapore's PDPA. You own the agent and everything it learns. We never share or sell your data, and when a chat gets tricky it hands the conversation to your team.
