"I think the challenges are the same in many businesses from an entrepreneurial perspective: what am I trying to do, what's the product, what's the service, and it's also quite critical to work out if what I'm trying to do has been invented already or how am I going to improve on what's out there already."

"My main recommendation, especially for people working in large tech companies, is to spend a significant amount of time assessing the opportunity, gathering feedback, challenging the idea, building relationships, understanding the startup world and even raising money before leaving their jobs."
