Episode notes
Home Depot Cart Beat A $150K Truck
- Marc Hyman built an iced coffee business using a gutted Home Depot Husky tool cart he made for under $1,000.
- At a two-day desert festival his setup cleared $8,000 net profit while a $150,000 pizza truck sat nearby.
Iced Coffee Scales Better Than Espresso Rigs
- Nitro and iced coffee are high-demand all-day products that don’t need a $30,000 espresso machine.
- Most revenue comes from iced/sweet drinks after 9 AM, so strip out expensive equipment and focus on speed and volume.
Design For Easier Labor With Bag In Box
- Solve human-factor constraints to widen operator pool: switching from heavy kegs to bag-in-box reduces lifting and lets smaller operators (divorced moms, military spouses) run carts.
- Bag-in-box keeps brew shelf-stable and easier to handle.
