Mentoring has been a great way to learn more about the startup community, rapid prototyping and lean startups. Early in 2016, Era Innovation and UQ ran a Lean Start-Up Challenge for students in the MBA program. I mentored a brother-sister team who are reinventing a family business – Roberts Traction Technologies. I was truly inspired by the commitment David and Sarah had to continue the success created by their parents. It was also fascinating to see the types of businesses in the competition and how the business models evolved using lean ideas.
