Riyadh Business Pulse

Culture Formal and traditional. Business hours are influenced by prayer times.
Lunch Break 1:30 PM - 2:30 PM.
Pro Tip The work week is Sunday to Thursday. Call between 10:00 AM and 1:30 PM. Avoid calling during the five daily prayer times (Salat). Business is highly relational and hierarchical; always address senior decision-makers with appropriate respect and titles.

San Francisco Business Pulse

Culture Innovation-focused and casual. Values disruption, speed, and technical excellence.
Lunch Break 12:30 PM - 1:30 PM.
Pro Tip Best reached between 10:00 AM and 4:00 PM. Expect a casual, tech-first vibe—informal language and dress are the norm. However, technical competence and speed are non-negotiable. Many in the Bay Area work non-traditional hours, but standard business times remain the safest bet.
