  • Strong intuition for markets, products, and customer psychology.
  • Background or deep interest in AI, SaaS, proptech, marketplaces, or automation.
  • A data-driven mindset balanced with the ability to make bold, intuitive decisions.
  • An extreme ownership mentality — you don’t wait for permission, you build momentum.
