Helsinki Business Pulse

Culture Extremely direct, honest, and values silence and deep focus.
Lunch Break 11:30 AM - 12:30 PM.
Pro Tip Best reached between 9:00 AM and 11:00 AM. Finns are remarkably direct and honest; do not waste time with small talk. Silence in meetings is a sign of thinking and respect—do not rush to fill it. Honesty and reliability are the most important business values.

Tehran Business Pulse

Culture Relationship-heavy and formal. Respect for hierarchy is paramount.
Lunch Break 1:00 PM - 2:00 PM.
Pro Tip The work week is Saturday to Wednesday. Thursday is often a half-day. Call between 9:00 AM and 12:00 PM. Iranian business culture is very formal and involves "Taarof" (a complex system of etiquette); be patient, polite, and avoid rushing into business without proper greetings.
