Sound Familiar?

Every month, you see your business costs go up.

Rent. Manpower. Operations. Everything.

So you spend more to grow revenue. But the marketing costs keep rising too.

You know your customers who bought from you loved their experience. Some left good reviews. A few even referred their friends.

But after that, most of them just never came back.

The revenue you are looking for is already sitting in your customer list. You just do not have the system to unlock it.

Who Is CS Koh

Hi, I am C.S. Koh

I spent 10 years doing hands-on marketing for SME businesses like yours in Singapore. Not as an agency. As a trusted marketing partner inside the business.

I sit down with you, look at your actual customers, and figure out together what makes them come back again and again.

I have done this for eCommerce brands, B2B project companies, and service businesses across Singapore.

Today I build AI marketing systems that help SMEs unlock the revenue sitting in their existing customer base.

I was once an SME business owner too. I ran a mobile phone retail business and a co-working office chain. I know what it feels like to spend $2,000 to $3,000 a month on ads and get close to zero results.

That experience taught me one thing: marketing is not just about numbers. It is about treating your customers like real people who trust you before they buy.

Hard Lessons From Real Businesses

What Did NOT Work

✗

Giving 40 to 50% discounts regularly. After a few rounds it stopped working no matter how much they gave.

✗

Selling products or services without knowing why customers actually needed or wanted them.

✗

Posting random content like holiday greetings and sending promotions to Facebook groups and forums.

✗

Creating expensive branded content that looked nice but did not address any real customer pain.

What Actually Worked

✓

Deep diving into the real problems and pains of their customer base that no competitor had ever shown they understood.

✓

Collecting testimonials and creating content that directly addressed those real problems and pain points.

✓

Building a process to engage customers regularly, including when they were not happy.

✓

Using AI to reach those customers via low-cost channels and generate repeat sales, even for new products and services.

Proof It Works

Real Businesses. Real Results.

The Process

Here is How We Work Together

01

WhatsApp Consultation

We start with a real conversation about your business. No forms. No pitch. Just an honest look at your existing customer base and what it could be doing for you.

02

We Build the System

I design and build the AI marketing system specific to your business, whether that is email, WhatsApp, or both, mapped to your customers actual behaviour and buying patterns.

03

Your Customers Come Back

The system runs. Your existing customers re-engage. You get repeat sales and deeper relationships without new ad spend or extra workload on your team.

Common Questions

Frequently Asked Questions

This is for founder-led businesses that have been operating for at least 3 years and have an existing customer base they are not fully monetising. If you are still building your first 100 customers, this is not the right fit yet. If you already have customers who bought from you but rarely come back, this is exactly what you need.
Most agencies focus on acquiring new customers through ads. I focus exclusively on your existing customer base. The two are not the same problem and rarely the same solution. I am not running your ads. I am building systems that activate the relationships you already have.
No. The SGVenusFlyTrap campaign generated 14x ROI from a list of under 2,000 customers. The AnneeMatthew 12.8x ROI campaign ran to 2,500 subscribers. What matters is not the size of the list. It is whether those customers had a real experience with your business and whether there is a genuine reason for them to come back.
For campaign-based work like email or WhatsApp outreach, results can come within days of launch. Restoration Essence saw 200 to 300% increases in order sizes within the first 2 months. That said, the speed depends on your customer list quality, your offer, and how well we understand your customers before we launch.
Every business is different, so pricing is scoped based on what your business actually needs. The best first step is a WhatsApp conversation. There is no cost to that conversation and no obligation to proceed. If there is a fit, I will tell you clearly what it involves and what it costs.
Click the WhatsApp button on this page. It will open a conversation with a pre-filled message. I personally read and respond to every message. From there we have a real conversation about your business and whether this is the right fit.
