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.

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.
