Who We Are
Smart, secure IT solutions with a personal touch.
At Seitfin, we specialise in delivering right-sized IT services for SMEs across Centurion, Pretoria, Johannesburg, and South Africa. We believe technology should be simple, secure, and empowering, not confusing or needlessly expensive. Our mission is to make IT support truly work for small and medium-sized businesses, providing reliable, scalable, and affordable IT solutions that help your business grow with confidence.
We do not believe in jargon, complicated contracts, or upselling services you do not need. Instead, we focus on practical, transparent, and business-aligned IT support that keeps your systems secure, your data protected, and your team productive.
Our Story
Seitfin has been supporting South African SMEs since 2017. The company was built around a simple frustration: too many small businesses were stuck with overpriced, oversized IT solutions that did not fit how they actually work. Co-founders Kobus Schlebusch and Janis Schlebusch set out to build an IT partner that puts client success, security, and integrity first, combining Kobus deep technical expertise with Janis focus on operations, transparency, and client relationships.
Seitfin was created with a simple vision: provide SMEs with honest, reliable, and scalable IT support designed around real business needs, not tech trends or high-pressure sales.
Our Mission
We support small and medium-sized businesses across Centurion, Pretoria, Johannesburg, Gauteng, and the wider South African market, helping them navigate the digital world with clarity and confidence. Whether you need managed IT services, IT support, Microsoft 365 management, cybersecurity, or web design, every solution is shaped around your budget, your team, and your long-term goals. Our goal is to be the most trusted IT partner for South African SMEs, known for our reliability, security expertise, and practical, hands-on support.
Our Values
Integrity & Transparency
We provide clear, honest recommendations based on what your business truly needs. No hidden fees. No unnecessary add-ons. No one-size-fits-all solutions.
Scalability & Growth
Our IT services are built to scale with your business. Whether you’re just starting out or preparing for expansion, we ensure your technology grows with you.
Partnership First
We act as a trusted IT partner, not just a support provider. Your success is our priority, and we tailor every solution to support your operational goals.
Proudly South African
We understand the local business environment and proudly support SMEs across Centurion, Gauteng, and South Africa.
