Our Services
Website Setup & Strategy
From structure to content, I’ll help you design a site that actually fits your business — using WIX or similar tools that are easy to manage.
Improve User Experience
When something on your site feels “off,” I’ll help you make it more intuitive and user-friendly — so visitors know what to do next.
Online Offer Clarity
Not sure how to describe what you do or sell? I’ll help you find the words and flow that make it easy for people to say yes.
Ongoing Support
For updates, tweaks, or second opinions — I’m here when you need me, no retainers or long contracts required.
From customer journey mapping to wireframing and prototyping, I help identify user pain points and create intuitive solutions.
UX Strategy & Research
Extensive experience designing for the Fintech and IoT sectors, delivering seamless and secure digital experiences for complex systems and tech solutions.
Fintech & IoT Expertise
Expertise in the media space, helping brands create engaging, user-friendly platforms that resonate with diverse audiences.
Media & Digital Platforms
Focusing on maximizing digital performance by refining user flows, enhancing usability, and increasing conversion rates. I work to ensure that your digital products not only look great but also work effectively to meet business goals.
CRO
With over 20 years of experience in UX design for large-scale platforms and enterprise solutions, I bring deep expertise to agencies and businesses in need of high-quality, short-term contracts. Whether you’re looking to optimize an existing product, redesign a user interface, or launch a new digital experience, I offer tailored solutions that deliver measurable results.
I’m skilled at quickly integrating into your team, adapting to different workflows, and collaborating closely with developers, marketers, and stakeholders. My approach ensures that designs aren’t just beautiful, but also align with business objectives and user needs.
I’ve spent over 20 years designing online solutions — from big enterprise platforms to small-but-mighty websites. My background is in User Experience (UX) design, and over the years I’ve worked with clients like Virgin Money Insurance, Standard Bank, Nedbank, Vodafone IoT, and Dentsu.
A lot of that time has been spent helping agencies shape better digital experiences — offering UX consulting that helps teams think more clearly about what users actually need, and how to make it all work in real life.
These days, alongside enterprise and agency work, I also love helping small business owners build a thoughtful online presence — something that feels like them, works for their goals, and doesn’t cause tech-related headaches.
Whether you need a new website, a second pair of eyes on your content, or just someone to help you figure out where to begin, I’m here to make it a little easier.
Testimonials
I have long standing relationships with a lot of my clients. These are just a few that have enjoyed working with over the years.
"As a first-time business owner, I had so many ideas and didn’t know where to start. Jaco gently guided me to focus on what really mattered to my customers and helped me shape a clear, beautiful online presence for my florist shop. Thanks to his support, I now have a Shopify site I’m proud of — and my very first happy customer!"

He has a way of turning complex problems into elegant, user-first solutions — always thoughtful, always reliable. He’s not just a consultant; he’s a true partner in the work."

What does
Serrewet mean?
Pronounced: SEH-rruh-vet → /ˈsɛr.rə.vɛt/
When I was a kid, I had a bit of a lisp and couldn’t quite pronounce my own surname, “de Wet.” Instead, I’d proudly introduce myself as “Jaco Serrewet.” It stuck — and became a long-standing family nickname that still makes people smile.
