Announcing the winners of the Build What’s POS_sible Hackathon
Congratulations to the winners!
Thank you to everyone who participated in Square’s first-ever Build What’s POS–sible hackathon. This year, participants got to build innovative applications using at least one of our customer solution APIs, including Customers, Gift Cards, Invoices, Loyalty and Team Management. Square has become known primarily for its payments and point-of-sale solutions, but there’s so much more. We wanted to host this hackathon to give developers the opportunity to build with these APIs, as well as collect feedback to continually improve upon our API offerings.
During the hackathon, participants utilized one or more of our customer APIs to build useful tools that help sellers scale and grow their business. We had several prizes, including a $20,000 grand prize, and categories for most creative use cases valuable feedback were also awarded. To no surprise, our developer community took the challenge in stride and we were impressed by the submissions we received from developers all over the world.
And now, the winners 🎉
The winners will share $100,000 in cash prizes. Scoring was based on the following judging criteria:
- Quality of the Idea: Includes creativity and originality of the idea
- Implementation of the Idea: Includes how well the idea was executed by the developer, how well the featured Square APIs were leveraged, and, if applicable, how creatively multiple Square APIs were used together
- Quality of the Submission Package: Includes the quality of the description, video demo, and any other materials submitted to Devpost and how ready the submission is for publication in the App Marketplace
- Potential Value to Square Sellers and Customers: Includes the extent to which the solution can improve the retail or e-commerce experience for Square sellers and/or their customers.
