We’re thrilled to announce our winner of the TechCrunch Disrupt San Francisco Hackathon, Carbon! The weekend-long hackathon began on September 6th at San Francisco’s Pier 48. With over a thousand registered developers, the competition was fierce. Judging the hacking outputs was a panel of notable tech influencers including Stephen Garcia, Director of Product Innovation at Netflix; Dr. Jhilmil Jain, the Head of Android User Research at Google; Sahil Lavingia, founder and CEO of Gumroad; Morgan Missen, founder of Main; and Nicholas Mitrousis, Group Technical Director at AKQA. Carbon team was comprised of Bay Area locals who are all part of the same company, 1StudentBody (1SB). The team included Rishi Mallik from San Francisco (who focused on UX and product feature development), Tyler Flowers from San Jose (who focused on iOS client development), Ash Bhat from San Jose (who focused on push notification server set-up and integration) and Kabir Mahal from San Francisco (who focused on iOS client development and Ruby on Rails backend development and Yodlee integration). Over the course of the event, Carbon built a financial tool that could change credit card transactions and our current purchasing experience. The tool leverages Yodlee Interactive Aggregation API in combination with item-level data on every credit card purchase to improve the point-of-sale experience. As shown in this demo, Carbon’s app provides users with improved security and a deeper understanding around purchases. The tool notifies users of each purchase, thereby preventing fraud, and automatically provides detailed purchasing information around each item, from each vendor, instead of just the dollar amount -- eliminating the pain point of collecting receipts and ambiguity of credit card balances. As the winning team using Yodlee Interactive Aggregation API, the members of Carbon were each awarded Dr. Dre Beats Pill speakers, as well as a chance to win a spot in Yodlee Interactive Incubator Program. Big congratulations to the Carbon team, and all other participants!
