NKF always grew organically and never experienced an exodus. By the early 1990s, NKF had grown to a size that necessitated some strengthening of its internal organisation. A managing board led by a managing partner was introduced in 1994.

NKF gradually took additional office space in Bahnhofstrasse 20, Bahnhofstrasse 18, Fraumünsterstrasse 15 and Poststrasse 5.
