AI-First Engineering
From Japan, For the World
We build intelligent software, AI agents, and digital products that help businesses thrive in the age of artificial intelligence.
Why we exist
As engineers working in Japan, we saw firsthand how businesses struggled to adopt new technologies — especially AI. The gap between cutting-edge research and real-world application was growing wider.
We founded Hoang LLC to bridge that gap: connecting Japanese business needs with Vietnamese engineering excellence, powered by AI-first thinking.
Today, we serve clients across Japan with both our own products and dedicated engineering teams.
