I was invited to do a keynote speech on Octalysis Gamification at the App Growth Conference hosted by RevenueCat. They were quite generous and bought five nights at this hotel with an amazing scenic view (on top of my Keynote fees, international business class travel expenses).

You can see that the view from the window during dusk is like a painting! 

RevenueCat said my talk was so popular afterwards they ordered a copy of my book to every attendee. At the conference, I also met a person who ended up live in Xindian (Taiwan) close to where I live! We both flew across the pacific ocean to encounter each other in this San Francisco conference. Pretty cool! 

I'll definitely be working with RevenueCat again whenever they want my involvement!
