I would invest in Addy.
This is a start-up that turns your street address into a tiny link.
As someone that deals with shipping (USPS, PayPal, Fed Ex, and UPS) 4-5 times a week, I see this as a huge opportunity.
Instead of filling out forms with 20 fields (First Name, Last Name, Street Address Line 1, Line 2, City, State, Zip, Phone etc). What if these shipping companies accepted Addy url’s? What if when I was going to ship an item to someone with an even-more-complicated-international-address I could just type/write To: addy.co/john.doe | From: addy.co/colter. That would be amazing.
What if instead of texing someone a long address you could just send them an addy url?
What if when I moved to a new address I could just log on to addy.co and change my address immediately, instead of going through USPSs ridiculous paper/time wasting channels?
That would be amazing.
