What We Do

Everything your business needs to grow online

No jargon, no bloated retainers. Just the marketing work that moves the needle for businesses in Thika, Nairobi, and beyond.

Website Design & Development

A fast website that looks sharp on any device and actually turns visitors into customers, not just a digital business card.

Built to convert

SEO That Gets You Found

We get you ranking on Google for the searches that matter, so people looking for what you sell find you first, not your competitor.

Long-term, compounding traffic

Google & Meta Ads

We run paid campaigns on Google, Facebook and Instagram built to bring in leads and sales, and we watch the numbers daily, not monthly.

Leads within days

Social Media Management

Content, captions, and a posting schedule that actually gets engagement, so your page looks active and your audience keeps growing.

Consistent brand presence

Branding & Graphic Design

Logos, color palettes, and brand guidelines that make your business look established and trustworthy from the very first impression.

Instant credibility

Content Marketing

Blog posts, articles, and video content that answer your customers' questions and quietly build trust before they even call you.

Builds trust at scale

Email & WhatsApp Automation

Automated follow ups that reach out to leads while you sleep, so fewer potential customers slip through the cracks.

Zero manual follow-up

Marketing Strategy & Consulting

Not sure where to start? We will map out a practical plan for your budget and your goals, then help you execute it.

A clear roadmap

How It Works

From a stranger online to a paying customer

This is the same simple process we use for every client, whether you are a shop in Thika or a company operating across Kenya.

Someone sees your ad

We put your business in front of the right people on Google, Facebook, or Instagram.

They land on your site

A fast, clear website (or landing page) explains exactly what you offer and why it matters.

They reach out

A simple form, call button, or WhatsApp chat makes it effortless for them to contact you.

You close the sale

We hand you a warm lead that is ready to buy. You just need to follow up and close.

We track what worked

We report back on real numbers: leads, cost per lead, and sales. Then we double down on what is working.

5+ Years Experience in Digital Marketing

Meet The Founder

The person behind your campaigns

Haggai G. Nkatha, Managing Director

The problem I found: too many good businesses in Thika and Nairobi were losing customers to competitors with a weaker product. The only difference was better marketing.

The solution I sell: marketing built around your business, not a generic package. A website, ads and content made to bring in paying customers.

My pledge to you: straight numbers, simple language, and work that earns your business every month. No long contract to trap you in.

Client Results

Real businesses, real results

Here's what a few of the businesses we work with in Thika and Nairobi have to say.

4.9/5.0

"Our Facebook page was basically dead before we called Donga. Three months later we are getting daily orders on WhatsApp, and I finally understand what I am paying for each month. They walk me through it every time."

Sarah Mwangi

Owner · Thika Fresh Grocers, Thika

5.0/5.0

"Cost per lead dropped by almost half in our second month with them. What mattered more is the quality. The people calling in could actually afford our listings, not just window shoppers."

David Kimani

CEO · Kimani Real Estate, Nairobi

4.8/5.0

"They rebuilt our website and it finally looks like a real business online, not a Facebook page pretending to be one. Bookings through the site now cover almost a third of our monthly clients."

Grace Njeri

Founder · Njeri Beauty Lounge, Thika

4.9/5.0

"What I liked was the reporting. No vague talk about engagement, just straight numbers on what we spent, what we got back, and what to try next. That is rare to find in this industry."

Peter Otieno

Director · Otieno Logistics, Nairobi

4.7/5.0

"We came in with a small budget and honestly expected to be an afterthought. Instead our Instagram following tripled and we started seeing real sales from it, not just likes and follows."

Mary Wambui

Owner · Wambui Boutique, Thika

5.0/5.0

"Professional and upfront about what would and would not work for a law firm. They did not just tell us what we wanted to hear. Inquiries from the website have more than doubled since the redesign."

James Mutua

Managing Partner · Mutua and Associates, Nairobi

4.8/5.0

"Healthcare marketing is tricky and they took the time to understand our patients before touching a single ad. Bookings for our clinic have gone up every month since we started, without gimmicks."

Ann Wanjiku

Founder · Wanjiku Health Clinic, Thika

4.9/5.0

"We had tried two other agencies before Donga and both just posted on social media and disappeared. This team actually calls, sends reports, and adjusts the plan when something is not working."

Brian Kariuki

Operations Manager · Kariuki Auto Spares, Nairobi

5.0/5.0

"I run a small interior design business and never thought I needed a real marketing team. Donga built us a simple portfolio site and now clients find us on Google before we even pitch them. Worth every shilling."

Faith Achieng

Founder · Achieng Interiors, Nairobi
