We build custom AI trained on our clients' internal data — their products, processes, and pricing rules — for accuracy you can trust in production. We specialize in construction, healthcare, home services, professional services, automotive, F&B, and beauty & wellness industries. ## 41 Closer (Flagship Product) 41 Closer is 41 Labs' flagship product: a WhatsApp sales agent that we build, run, and tune for a business. It answers customer messages in seconds, 24 hours a day, gives accurate prices from the client's real catalogue, follows up every lead, and closes the sale, handing off to a human when needed. Unlike a DIY chatbot tool, 41 Labs handles everything and controls the AI for the client. It is fully done-for-you and priced on the value it brings, not per seat. Plans start at $690 per month (Pro $1,490 per month, Enterprise custom). Live demo: message +65 8012 4848 on WhatsApp and 41 Closer itself replies.
