Build Block
Build Block is a Korea-founded real estate company that gives Korean investors and companies a single, end-to-end path into the U.S. property market. What began as a cross-border investment platform lowering the barrier for individual Asian investors has grown into a full-stack operator: brokerage, architectural design and permitting, construction management as a general contractor, and post-investment asset and facility management. Today it also builds the physical backbone of the AI economy - data centers and EPC plants for semiconductor, battery, and advanced manufacturing - for Korean firms reshoring to the United States.

Now a subsidiary of Tutor Perini, it employs roughly 740 people and reports about $307 million in annual revenue.
