The problem
Every late reply sends the booking to the next shop.
Slow replies lose the enquiry.
Customers message a few shops. The first one to answer gets the sale.
Quotes go quiet.
The buyer goes quiet after the quote. Nobody has time to chase.
You answer chats at 11pm from bed.
Because if you wait, they message the next shop.
Your team goes home at 6pm.
The enquiries keep coming all night and all weekend.

From the founder
Why I built 41 Sales Team
At 2:02am, a customer asked a Singapore car rental for a 7-seater to KL. The first human reply came at 9:03am. They never wrote back.
That company is open 9 to 6, seven days a week. At 2am, the team was asleep.
A swim school owner told me the same thing. She runs it alone. Her enquiries come in after 10pm, when she is finally resting.
A car rental owner told me his customers contact about five companies. Whoever answers first gets the booking.
I ran a tent business in Bali and Jakarta. Everything ran on WhatsApp, even the legal documents.
You should be able to rest after 10pm and still get the booking. So we built an AI sales team that answers in seconds, at any hour.

What owners ask us
Is 41 Sales Team the same as 41 Closer?
Yes. 41 Closer was renamed 41 Sales Team in October 2026, and it is the same product from 41 Labs.
What does it cost?
Your first 100 sales conversations are free, then from S$299 a month. You never pay for seats, and every tier is on our pricing page.
Is there a contract?
No. It is month to month. Stop any time with one message.
Will it sound like a bot?
It sounds like your team, trained on your products, your prices and the way you talk. You test it yourself before it goes live.
Will the AI get it wrong?
It quotes only from the prices you approved. Anything else comes to you as a WhatsApp alert, and you can pause it in one tap.
Do customers need a new number?
No. We connect your existing WhatsApp Business number.
Can my staff still reply?
Yes. Anyone on your team can take over a chat in one tap, with the full history.
What languages does it reply in?
Your customer's language. If they write in Chinese, it answers in Chinese.
What do I need to prepare?
Just your website. We build your AI from it, then connect your WhatsApp number and payment links with you.
How long does setup take?
We build it before the call and you test it there. Your number goes live once Meta approves it, usually in one to two weeks.
Will it connect to my system?
Google Calendar, Outlook, Stripe, Airwallex and Attio are included, plus Plato for clinics. For anything else, we check first and quote before we start.
Is my data safe? Will I get banned?
Your data stays yours, and we process it only for you under the PDPA. It runs on Meta's official WhatsApp Business Platform.
How is 41 Sales Team different from inbox software?
Inbox software gives your team a place to reply. 41 Sales Team does the replying, and we set it all up for you.
What if it does not work for my business?
You see it work on your own business before you pay. There is no contract, so you can stop any time.
