Hey, I'm Kostas.

I’m good at two things only

First is my ability to fail fast and hard - and move on. This has allowed me to very quickly prototype, experiment and iterate my way to solutions to some very painful problems in marketing, sales and product. Second, I’ve got a record of finding and retaining the right people in design and development, transforming them from individuals into effective delivery teams.

Here's what I've done so far
