Rome Business Pulse
- Culture Formal but passionate. Relationships are built over coffee and long discussions.
- Lunch Break 1:00 PM - 2:30 PM.
- Pro Tip Call between 10:30 AM and 12:30 PM or 4:00 PM and 5:30 PM. Avoid the 1:00 PM - 2:30 PM lunch break. Italians value relationship building ("La Bella Figura"); always maintain a professional but warm and engaged tone. Business slows down significantly during the "Ferragosto" period in August.
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.
