Jakarta Business Pulse

Culture Collectivist and polite. Respect for elders and social harmony (Gotong Royong) is important.
Lunch Break 12:00 PM - 1:00 PM (11:30 AM - 1:30 PM on Fridays).
Pro Tip Best call window is 9:30 AM to 11:30 AM. On Fridays, avoid calling between 11:30 AM and 1:30 PM due to congregational prayers. Indonesians value "face" and social harmony; avoid being overly blunt or confrontational. Relationship building is a critical first step for any business deal.

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.
