Experience that carries.
Energy that thinks ahead.
Founded 2007.
Grown through trust.
RF BAU was founded in November 2007, initially with temporary staff, then with the first permanent employees. Within a few years, the team grew to over 10 employees, complemented by a strong network of partner companies. Grown not through noise, but through quality, reliability and trust.
With a younger partner joining from 2026, a new chapter begins: Proven values remain, structures, appearance and processes are being developed further. New website, new office, new branding.
The future is being built. With yesterday's experience.

Recommendation
Faces instead of anonymous processes.
