Thiago Mata

Technology Leader

Technology leader who connects engineering to business outcomes. Over twenty years across startups, ad-tech at billions of transactions, and regulated banking have shaped how I choose what to build, what not to build, and where to invest, and how I lead teams that decide well today and better tomorrow, always favouring clarity over cleverness and reliability over novelty.
