Video is moving online in a big way. It's proven to be a challenging market for some companies that start out as a pure Internet company such as Joost.

The Chinese market is very, very unique.

Silicon Valley is the best place to start a tech company in so many ways.

When a business becomes successful seemingly overnight, no one knows about all the months and years you've invested, all the projects you've tried before that didn't work.

Look for when the environment is changing - the big shift now is mobile Internet. It's really happening big-time. The way you interact with services on a smart phone compared to the Web is quite different, so there's a huge opportunity.

When we started Skype, if you look at analyst reports, no one forecasted it as a big business. Also when Google started, it was not fashionable to be in search. It's not trying to do the obvious - that's the hard part.

I hope that my investment into Atomico will become my best financial investment to date.
