Boston Business Pulse
- Culture Academic, professional, and values innovation in biotech and education.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Best reached between 9:30 AM and 11:30 AM. Boston is a city of high intellectual standards; ensure your technical data is solid and your arguments are logically sound. The culture is professional and slightly more reserved than New York, with a high respect for expertise.
Seoul Business Pulse
- Culture Extremely hardworking and hierarchical. "Pali-pali" (hurry-hurry) culture drives rapid growth.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The ideal window is 9:30 AM to 11:30 AM. South Koreans value speed ("Pali-pali") and expect rapid responses. Avoid the 12-1 PM lunch hour strictly. Ensure you follow hierarchical protocols if senior leaders are present, and never arrive (digitally or in-person) late for a call.
