Studying multiplicity properties of stars is very important in the context of star formation but in which environments can we study primordial multiplicity with little influence from dynamical interactions? The SACY (Search for Associations Containing Young stars) sample offers such an opportunity, it is comprised of 9 nearby, young associations (< 150 pc, ~5-100Myr), allowing a huge, and continuous, range of orbital periods to be probed. We present multiplicity results of the close-companion frequency in the SACY sample using spectroscopic techniques and comment on their implications for star formation.
