Is the rapid expansion of AI companies into office space a sign of sustainable industry growth?
Fireworks AI has secured 105,000 square feet of office space at 450 Concar Drive in San Mateo. This new lease provides the company with nearly five times the space of its current 21,800-square-foot headquarters.
Why it matters
The move highlights the ongoing growth of AI and robotics firms in the Peninsula region. These companies are increasingly fueling demand for large-scale office environments near major transit hubs like Caltrain stations.
The new facility at 450 Concar Drive spans a total of 210,000 square feet, taking over space previously occupied by Snowflake. This expansion occurs as Silicon Valley office leasing activity reached 3 million square feet in the third quarter of 2026.
