Courageous Leadership for Challenging Times
SISU is a unique Finnish concept. It stands for the philosophy that what must be done will
be done, regardless of what it takes. SISU is a special strength and persistent determination
and resolve to continue and overcome in the moment of adversity…an almost magical
quality, a combination of stamina, perseverance, courage, and determination held in
reserve for hard times. The SISU Group is committed to developing leaders who act with
courage in every area of life.
