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.
Sao Paulo Business Pulse
- Culture Warm and relationship-oriented. Personal touch and face-to-face (or video) meetings are preferred over emails.
- Lunch Break 12:30 PM - 2:00 PM.
- Pro Tip Mornings can start slowly; the most productive time for calls is between 2:30 PM and 5:00 PM. Avoid scheduling anything critical for Friday afternoon, as many locals begin their weekend travel early. Brazilians value personal warmth; always include a friendly greeting.
