Based on the research, the minimum meaningful investment is access to certified enclosed acoustic space for focused individual work — the single factor that most directly addresses why hybrid employees choose home for their most demanding tasks. One HIGHKA Model S or M pod per 10–15 employees provides the baseline. This investment is also the most reversible: pods are movable equipment with full residual value, not leasehold improvements with zero exit value. The investment commits no capital permanently and generates immediate acoustic and attendance returns from deployment day.
