Alex Ember, a photographer, and Dan Kaminsky, a hacker, collaborated on an SMS payment app for a silent auction, ibuy.io, which allowed attendees to bid anonymously via text message. The app was created to automate the bidding process and add fun to the night. Dan's expertise in security systems and Alex's artistic background came together to create a seamless experience for bidders, who could view prices and receive notifications via SMS. The app is not for sale but will be made available to lower the barrier of inquiry for buyers, making it easier for people to engage with art.
