Carl Sjogreen

Builder of Things | Co-founder of Seesaw, Creator of Google Calendar

I have successfully co-founded and sold four companies and have done a bit of everything in those roles. I have also led Product Management teams at Google & Facebook where the products I worked on are used by hundreds of millions of people every day.
