Performance should feel empowering,
not exclusive.
Built by athletes, SIRRA creates performance tools designed around the athlete, how they train and what will benefit them the most.
This is so athletes can get more from every session.
Built from the sport
Sports performance technology especially in rowing has become more expensive, more out of reach, without providing any additional value.
SIRRA was created to change that.
Founded by Perth rower and industrial designer Peter Holliday, SIRRA exists to make performance accessible to every athlete, so athletes can get the most out of their training, and perform better every day.
