  • Lunch Break 12:00 PM - 1:00 PM.
  • Pro Tip Best times for calls are 9:00 AM to 11:30 AM. Chicagoans are known for being practical and direct but also friendlier than their East Coast counterparts. The Central Time Zone is the "Goldilocks zone" for North American business, allowing for easy syncs with both NYC and LA.

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.
