I proposed an idea to speak at O'Reilly Fluent in San Francisco. This was a local event. The event gave me a free ticket, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer did not pay my travel expenses, and I was working while speaking at the event. It took me 20 hours to prepare for my 25 minutes speaking slot, and I had a mostly good time. I'm a person who has been speaking for 2 years. This was a for profit event.
