Big Mouth Marketing started in 2012 as a software company. For over a decade we built websites, ordering systems, POS and back-office software for Singapore businesses, and ranked their sites on Google. We did not start as an AI company. In 2012 AI was not there yet.
About two years ago we began deploying AI for clients, building on the systems we already ran for them: WhatsApp agents that answer and book, automated quotations and invoices, and lead generation that runs by itself. Because we are software people first, we connect AI to real data and real workflows instead of leaving it as a chatbot on the side.
Today we build WhatsApp AI agents, sales automation, SEO-optimised websites and AEO content strategies for SMEs in Singapore, all under one roof, with one team accountable for every result.
We believe every SME deserves a team that never sleeps — and that AI, done properly, is the most powerful lever a growing business can pull right now.

Our agents never clock out, even on public holidays
We believe every SME deserves a team that never sleeps. Our AI agents handle enquiries, bookings and follow-ups while you focus on growing.
See AI AutomationThree principles that guide every system we build, every campaign we run, and every client we take on.
We measure everything. If an AI agent isn't delivering ROI — fewer no-shows, more conversions, faster response — we rebuild it until it does. No vanity metrics.
Our systems are designed specifically for Singapore SMEs — right-sized, practically priced, and built for real operations, not enterprise pilots.
We're not a vendor — we're your AI team. From strategy to deployment to ongoing optimisation, one team is accountable for the full stack and every outcome.
We learn your operations — where time is lost, where leads drop off, what your customers ask most. This shapes the entire AI architecture.
We design your AI system — channels, integrations, conversation flows, escalation rules and KPIs. You approve before we build a single line.
We build, test with real traffic, refine, then go live. No surprises — you see every step, and we don't declare done until the numbers confirm it.
Monthly reviews, continuous tuning, and proactive upgrades as AI capabilities expand. Your system gets smarter the longer we work together.
Table bookings, no-show reminders, menu enquiries and review collection — all handled by AI via WhatsApp.
Appointment booking against live staff schedules, rebooking nudges and after-visit review flows.
Product Q&A, order tracking, abandoned cart follow-ups and loyalty messaging — all automated.
Lead qualification, listing matching, viewing scheduling and buyer follow-up — so agents focus on closing.
Appointment booking, pre-visit FAQ and post-visit follow-up — fully PDPA compliant.
Lead triage, consultation scheduling and proposal follow-up for law firms, accountants and consultants.
