I proposed an idea to speak at BI2015 in Nice, so I travelled internationally to speak. The event gave me a free ticket, and I was not paid to speak. The event assisted with part of my travel and accommodation. My employer paid all of my travel expenses, and I was working while speaking at the event. It took me 10 days to prepare for my 75 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 10 years. This was a for profit event.
