Marcos Aguayo

CTO & Software Engineer

Summary

CTO and software engineer in Barcelona. For more than fifteen years I’ve designed, built and run the technology behind products: web platforms, APIs, mobile apps, data and AI, and lately the machines too. Four times a co-founder and CTO. Most useful where the problem is as much about the business as about the code.

  • 15+ years building software
  • 4× co-founder and CTO
  • 26+ products and platforms shipped
  • €3.5M raised with a founding team
