I've been an internet entrepreneur for the last 14 years since 2005, starting with Kiko, a calendar service that launched just before Google Calendar.

After selling Kiko Calendar on eBay for about $4 million, we realized we wanted to continue pursuing startups, despite not keeping all the money from the sale.

Kiko didn't succeed, and we ended up fire-selling it on eBay after several failed acquisition attempts.

Structural advantages can be a significant concern; for example, when Google Calendar launched, it crushed a competing calendar startup.

After Kiko, we launched Justin.tv, a live streaming platform where I wore a camera on my head to broadcast my life.

I believed strongly that Google Photos would be a billion-user product, so I continued to work on it despite being told not to, which led to conflicts with my bosses.

After initially exploring various projects, we realized we should have focused on the captions app, which was already successful without any updates.

On our first day at Google, we found out that all our plans were changed, and we were assigned to work on Google+ instead of Google Photos, which created a lot of conflict for me.

Our first idea was to create an app that digitized catalogs, which we called Tote, but it faced challenges in development and approval.
