What it’s costing you

The Hidden Cost of Slow Replies

Every WhatsApp you don’t reply to, your competitor does.

  • 78% of leads buy from whoever replies first.

    Your competitor replies in 5 minutes. You reply in 4 hours. Who gets the deal?

  • Your best leads come at 9PM. Nobody’s replying.

    Evening and weekend WhatsApp inquiries are the bulk of your volume. A 16-hour silence kills a hot lead.

  • A sales coordinator costs S$5,000 a month. Still forgets to follow up.

    CloserAI is S$250/month. Replies every time. Never calls in sick.

You reply fast at 2PM. But what about 9PM? Weekends? CNY?

52% of your WhatsApp leads arrive outside business hours. 56% of customers abandon a purchase when a business takes too long to reply.

What it does

Everything a great salesperson does.
Without the salary.

Human pacing

Replies like a salesperson. Not like a bot.

Most AI chatbots fire off replies in 3 seconds. That’s how prospects catch them. CloserAI waits, reads the full context of what they wrote, then replies once in under a minute. Human pacing, your voice, zero bot-spam.

  • Official Meta WhatsApp Business API, zero ban risk
  • Batches rapid-fire messages so prospects get one thoughtful reply, not three robotic ones
  • Responds in English and Singlish natively
  • Understands voice notes, images, and emoji

The leak

At your current response speed, you’re missing roughly

+4.8deals /month

That’s around S$48,000 in revenue walking to competitors.


CloserAI replies in under a minute, like a human would. Those are the deals you’d catch back, every month.

CloserAI Starter is S$250/month. It pays for itself by catching just one extra lead.

Based on MIT Lead Response, Velocify (2016), and Optifai (2026) benchmarks.

How we calculated this

How we calculated this

We use response-time conversion benchmarks from the MIT Lead Response Study, Velocify (2016, millions of lead records), and the Optifai Pipeline Study (2026, 939 companies).

  • Under 1 minute: ~21% of leads convert
  • 5 to 60 minutes: ~10%
  • 1 to 6 hours: ~5%
  • Same day: ~3%
  • Next day or later: ~1%

CloserAI’s under-1-minute pacing is designed to deliver the 21% benchmark. Your actual results depend on your offer, market, and follow-up systems.

FAQ

Questions people ask before signing up.

Can’t find what you need? Message our demo line. A real answer in under a minute.

No. Two reasons. First, we train a voice profile on 25 to 100 of your actual WhatsApp messages. CloserAI uses your phrases, your greeting style, your Singlish level, your emoji habits. Second, it replies at human pacing, not bot pacing. Most AI chatbots fire back in 3 seconds, which is the dead giveaway that it’s a machine. CloserAI batches, reads, and replies in under a minute, like a real salesperson. Most prospects can’t tell.
