Lyra x Product Counsel Hackathon
Builders Hack, brought to you by Lyra and Product Counsel.
A mystery brief. A weekend to build. Then a room full of people ready to see what you've made.
Build from Friday 9 October at 9am through Sunday 11 October, then join us at Lyra on Friday 16 October for demo night. The top 10 teams will present their work, with a $1,000 cash prize plus two mentoring sessions with the Rampersand team up for grabs to help you develop your startup.
Engineers, designers, product people, growth people, students and founders are all welcome. If you like making things and figuring out how they could work in the real world, this is for you.
