Lyon Business Pulse
- Culture Traditional but innovative. Values both industrial heritage and world-class gastronomy.
- Lunch Break 12:30 PM - 2:00 PM.
- Pro Tip Never call between 12:30 PM and 2:00 PM; the lunch break is strictly for dining and networking. Tuesday and Thursday mornings are typically the best for reaching senior leaders. Business culture is formal and values long-term personal trust.
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.
