"SOU" is a real estate token securities platform that securitizes high-value commercial real estate, allowing it to be bought and sold in small amounts like stocks. It is creating a real estate investment market where any general investor can trade regardless of investment scale. By providing information including commercial area analysis to support customer decision-making, it makes information accessible to everyone, aiming to reduce the fundamental entry barriers of the existing real estate investment market — capital size and asymmetry of opportunity.
