Born out of real
world challenges

Fonoa AI was born out of first-hand experience that what holds businesses back from global growth isn't a shortage of ideas but a lack of tax understanding.

While at Uber, our founders saw that to scale at the speed required to succeed in a modern digital business, it's impossible to rely on manual processes to maintain a strong hold on tax obligations and achieve a complete real-time view of finances. Cross border rules are too complex and fast-changing to navigate compliantly without automation.

They brought together a team of leading developers to design a platform that is always up-to-date and automating action in the background, allowing our customers to focus on strategic growth. When your business spots a new market opportunity, we want everyone to celebrate, not at a desk working out the compliance issues.
