What do I do with my build after MakeOHI/O?

Our year-end tech showcase features projects from events throughout the year including HackOHI/O, MakeOHI/O, Datafest, IdeaPitch and more. Create your build this weekend, then work with us to expand and polish your project to present it to Columbus tech professionals in April.

OHI/O Sustainability Team:
OHI/O is working hard to create a year-round community of builders and hackers that are excited about creativity and technology. We will be offering a number of resources and mentorship opportunities to builders that continue to work on their projects throughout the year.
