About Yannis

  • 10+ years in web and marketing
  • 2016 founded Proof of Pixel
  • 5 cities, one team

Yannis Spanenburg has spent more than ten years building websites and the marketing behind them, and founded Proof of Pixel in 2016: a marketing and consulting agency for businesses that live on enquiries and orders, working from Dubai, New York, London, Antwerp and Malaysia. He builds the websites, the tracking and the follow-up automation behind practices, agencies, builders, studios, firms and shops, and the commercial strategy that ties them together.

Five of those years were spent shipping in Web3, crypto and fintech, from an on-chain affiliate and rewards dashboard to a real-time global tax and licensing platform built end to end. He writes here about what moved the number, not what sounds good in a deck.
