It closes the deal
while you sleep.
A customer messages your WhatsApp at 2am. Nobody answers. They buy somewhere else. That sale is gone, every single night. 41 Closer answers in seconds, quotes your price, and takes the payment. We build it. We run it. You wake up to the money.

41 Closer is a managed AI sales agent on your own WhatsApp number. It answers every customer in seconds, at any hour, quotes from your real prices, asks the one qualifying question, and takes the payment or books the slot. 41 Labs builds it before you pay and runs it for you. From $690 a month, build included.
We measured the gap it closes. One real enquiry sent to 25 Singapore businesses between 8pm and 11pm: one replied within five minutes, the median wait was 13.3 hours, four never replied. The study is linked below. Read the study.
The build is free. You pay monthly.

One plan sits above these. Past about 6,000 new customers a month, or more than one brand, Custom starts at $7,900. Ask us which one fits.
No contract. One month to start, charged from the day it goes live, not the day you sign. Month to month after that, 30 days notice. We tell you at 70% of your plan and again at the limit, so there are no shock bills.
The customer numbers are estimates. Each plan includes a set amount of usage, and we divide it to show roughly how many new customers that covers. Prices in SGD. No GST is charged. Pay for a year up front and you get twelve months for ten. Eligible Singapore SMEs can apply the EDGE grant, which replaced the EDG on 30 September 2026, to part of the cost. Plan terms and fair use.
You send a list. We do the rest.
You send your list
Your products and prices, and a bit about how you sell. A photo of the price board or a voice note is fine. That is the only work on your side.
We build it. You message it before you pay.
We train it on your prices, give it your voice, and put it on a test number. You message your own agent the way a customer would. Nothing is paid yet.
One free hour, then live
We walk you through the platform, connect your payments and your WhatsApp number, and switch it on. Live within 48 hours of your list. Billing starts the day it goes live.
It does not just chat. It closes.
Three messages your customers send today, and what the agent does with each.
Prices and names above are examples. When a chat gets tricky, or the customer asks for a person, it hands over to your team with the whole history.
It is already running real businesses.
It quotes live from the supplier's own catalogue, replies in seconds day and night, and our team steps in only for the tricky ones. It does not go off script, because we set the guardrails and watch it.
In our published quote-automation case, quote time went from 3 hours to 5 minutes, errors fell 90% and sales capacity rose 35%. Read the case.
Who should not buy this.
If you get a handful of enquiries a week and someone answers them the same day, a WhatsApp auto-reply is enough, and we will tell you so. 41 Closer pays for itself when messages arrive after hours, or faster than one person can answer.
Why I built this.
I watched good businesses lose sales for one reason. The customer messaged, and nobody answered in time. The product was right. The price was right. The reply was slow.
41 Closer fixes that one thing. It answers every message, every hour, and follows up until the customer buys or says no. We build it, run it, and keep making it better.
If you do real business on WhatsApp, message the agent and see for yourself. If it impresses you, message me.

What buyers ask before they start.
What is 41 Closer pricing?
Starter is $690 a month, Pro $1,490, Scale $4,300, and Custom from $7,900. The build is included in every plan. Pay monthly by card or bank transfer. One month to start, charged from the day it goes live, then month to month with 30 days notice and no contract. No GST is charged.
Is there a build fee or a setup fee?
No. We train it on your products and prices, give it your way of talking, connect WhatsApp and switch it on, all inside the plan. The only one-time cost is connecting a system of your own that we have connected before, which is $2,400.
What do I need to give you?
A list of your products and prices, and a bit about how you sell. We do everything else.
What happens if I get more customers than my plan?
It keeps answering. We tell you when you reach 70% of your plan and again at the limit, so there are no surprises. You pick the next plan when you are ready.
Will the price go up later?
Your price stays fixed while you are on the plan. If we ever raise prices, existing clients get 60 days written notice first.
Does it use my own WhatsApp number?
Yes. It runs on your business WhatsApp number through the WhatsApp Business API. We connect it for you. Your customers see your brand, not ours.
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. If your customers write mainly in another language, ask us before you count on it.
What if it does not work for me?
You stop. One month is the only commitment you ever make, then month to month with 30 days notice. There is no guarantee attached, because you message your own agent before any money moves. You own the agent and everything it learns, and we never share or sell your data.
Stop losing sales tonight.
Message it on WhatsApp right now. Ask it anything your customers ask. Watch it close. Then pick a plan.
