When most 18-year-olds were focused on exams, sports, or making weekend plans with friends, Hoërskool Stellenbosch learner Juwan Dippenaar was busy building a solution to one of the agricultural industry’s biggest inefficiencies – effective communication.
The idea for Reidar, a web-based platform designed to streamline operations for agricultural trading firms, began quietly in Juwan’s parents’ home office around 2021. His parents run an agricultural trading company, and he often found himself surrounded by the constant ping of WhatsApp messages, emails, and phone calls. “It was easy to see that this industry had communication and network inefficiencies,” he recalls. “Everything, from price discovery to logistics, was happening over endless message threads and phone calls.”
That realisation planted a seed, and over two – three years, Juwan began experimenting with sketching mockups, testing prototypes, and eventually creating an early MVP (minimum viable product) using Notion databases. “Looking back, the product we have today is remarkably close to that first concept,” he says. “Just a few extras and adjustments as new discoveries were made, and there are now much better user interfaces.”
In 2024, he officially registered Reidar with the CIPC, becoming the sole director at just 18 years old – that was approximately ten months ago. The platform he created helps traders and firms manage inventory, clients, routes, admin, and communication – from one central platform.
From Pretoria to Strand: A journey of building and belonging
Born in Pretoria East, Juwan’s entrepreneurial journey began early. After moving with his family to Strand, Cape Town, he watched his parents build a new life by flipping a local car wash into a thriving trailer hire business. “I remember my father inscribing the date in the cement of the building’s new fence, symbolising ownership and pride”, something that stuck with Juwan through the years until he would eventually negotiate a deal with his father to earn a 3D printer if he maintained a 90% average. To no surprise, he did, and soon Juwan would launch his first venture, JAM3D Designs, offering custom design and printing services. Though small, it gave him his first taste of entrepreneurship.
Then Covid-19 hit. Juwan’s parents began afresh with their own agricultural trading business, operating out of their family home, and giving Juwan a front-row seat to the complexities of running a business. “This gave me the unique opportunity to observe a business’ conception and growth right from the very start. My parents welcomed interactions between myself and their growing office personnel, and I often did my homework at a desk inside their office.”
Building Reidar
Before Reidar’s official registration, Juwan spent two and a half weeks, during his school holiday, glued to his chair – building the first version of the web application. “I’m not a coder,” he admits, “but I understand systems.” Using no-code and AI-assisted tools, he built a product that rivalled those made by teams of developers.
That system now manages:
- Over R70 million in quotations;
- More than 100 active clients for a single trading firm; and
- Automated communication on R15,000+ worth of contract deviations.
And this is just the beginning for Juwan. The startup is currently piloting with a trading firm in the Western Cape, and plans to expand integration to transporters, feedlots, mills, and farms – creating a connected ecosystem for the entire agricultural value chain. Thereafter, they aim to massively scale their solution and client base. They also have other projects in the loop which will massively strengthen market-integration with the web-based platform – for now, the details are still under wraps.
“Think of it like an ‘Uber for agricultural trade.’ Connecting traders, farmers, and transporters in real time unlocking efficiency and opportunities at an unprecedented scale – initially nationally, with potential to expand further.
Lessons from an 18-year-old founder
Building a complex tech startup without a technical background, while simultaneously still finishing matric, has been no small feat. But Juwan sees challenges differently. “I love this problem,” he says. “It’s not about writing code, it’s about designing systems that make sense.”
By combining a systems-first approach with no-code and AI-assisted tools, he was able to build a fully functional product that rivals what a team of traditional developers could produce – all through careful design, rapid iteration, and understanding how each piece interacts.
He believes deeply that the future belongs to young, self-taught builders. “Degrees are enhancements, not requirements,” he says. “The world is full of tools that lower barriers, from AI to no-code platforms. What matters is agency: your ability to move, decide, and create,” and he encourages young people to start building even before studying formally, learning and growing as they go.
Advice for young entrepreneurs
His message to other young founders is simple but powerful:
“Build what bothers you. The best ideas are born out of irritation, not inspiration.”
He encourages others not to be intimidated by complex industries or the idea of being “too young.” “Naivety and optimism are superpowers,” he explains. “You’re young enough to ask why, and bold enough to be able to change it.”
What’s next for Reidar?
Reidar’s immediate focus is refining automation and transport coordination features, with exciting plans to launch its multi-firm ecosystem soon. But beyond technology and traction, Juwan is eager to connect with others who can help him grow.
“I value being teachable, and I’m always looking to learn from people with experience,” he says.
