AI @99xAmericas
Future proof engineering with AI
We’re a software development company first. AI is a powerful enabler but can create fragile systems when misapplied. If models generate large swathes of application logic without review, it can lead to inconsistent architectures, hidden dependencies, security gaps, and growing technical debt. At 99x, we use AI deliberately, inside a specs-first, modular architecture and with human in the loop review to get speed gains without losing control. And if AI is not desired, we can simply not use it — our core strength has always been robust engineering expertise.
