In a conference call world, it’s easy to forget that a little human presence goes a long way in connecting with potential partners, investors and collaborators. It’s even easier, though, to forget some essential items while you’re away on business. Every traveller has their must-packs, and they range from portable chargers to good old paper and pens.

Due cofounder John Rampton’s essential business trip charm? Breath mints. “There is nothing worse than talking to someone for 5 minutes with bad breath. You literally will not hear a word that comes out of their mouth and you’ll be thinking about what you can do to get out of there. My recommendation is to take enough mints so that you can pop one in your mouth every 30 minutes.” Now that’s a good call!
