What drives me.

  • Startups.Small teams, big ambitions. I think the future is built here.
  • Technology.Since I was a kid. What started as curiosity for how things work turned into a craft.
  • Sport.What holds the rest together. Clear head, awake body, ordered day.
  • Curiosity.The trait I respect most. Wanting to understand everything opens more doors than talent.
  • Long-term mindset.Enjoy the process, decide looking ten years ahead. Boring usually wins.
  • Future business models.The rules change fast. I'm fascinated by how money will be made in what's coming.
