Who We Are
Smart, secure IT solutions with a personal touch
About us
At Seitfin, we specialise in delivering right‑sized IT services for SMEs across 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 don’t believe in jargon, complicated contracts, or upselling services you don’t 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 was founded by Kobus Schlebusch, an experienced IT professional with more than 20 years of hands‑on technical expertise in server support, cybersecurity, and Microsoft 365 services. After seeing countless South African SMEs struggle with overpriced and oversized IT solutions, Kobus set out to build an IT partner that puts client success, security, and integrity first.
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, 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, or SME‑focused cybersecurity, every solution is shaped around your budget, your team, and your long‑term goals.
Our goal is to become 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.
