She said the event will get the help of volunteer web designers and technical teams, as well as some of Northland's business community.
"Nobody is being paid for this - we are all volunteers."
Once teams were formed, they would work on business plans with mentors on site before moving to market research in Whangarei on the day.
"This is about getting out and getting face-to-face feedback," said Ms Williamson.
Teams will then need to carry out their plans and develop a prototype, which judges will then test out.
She said the event aimed to help participants learn new skills and hopefully, help them get their ideas off the ground.
Chamber of Commerce Northland and Northland Inc are supporting the event. The venue has yet to be decided and judges were still being signed up. Admission would cost less than $100 and would include seven meals throughout the weekend.
-Tickets will be available in coming weeks. To get some, stay tuned to Startup Weekend Whangarei on Facebook.
