Silicon Valley

China’s “996” work culture (9 a.m. to 9 p.m., six days a week) is gaining traction in the U.S., particularly among Silicon Valley AI startups. Some companies openly advertise or require this demanding 72-hour workweek, with a readiness for “996” becoming a pre-screening factor for candidates. New York-based Rilla, an AI startup, explicitly requires over 70 hours per week. While extended hours are rising globally, American companies show more enthusiasm for this model than European ones, with some arguing even “996” is insufficient.

Newmark facilitated Zscaler’s 301,163 sq ft sublease for its new global HQ at 4301/4401 Great America Parkway in San Jose, Calif.—silicon Valley’s largest post-pandemic cybersecurity-driven office deal. The move signals tech firms’ strategic return to premium spaces amid hybrid work norms, aiming to centralize operations, boost talent retention, and accelerate AI innovation. Vice Chairman Mike Saign and Senior Managing Director Rich Hoyt led the transaction, highlighting Zscaler’s focus on physical-collaboration synergy. Despite Silicon Valley’s office market challenges, this deal showcases demand for specialized spaces aligning with high-growth sectors like cloud security.
