As answered by people managing Project Euler and VUJIS.
VUJIS's answer:
Most tools stop at shipment records. Vujis goes further with integrated AI features:
All powered by the flexible and transparent Vujis Credit System.
VUJIS's answer:
Because Vujis doesn’t stop at just showing trade data — it actually helps exporters close deals.
Most competitors dump you with shipment records or generic contact lists. Vujis goes several steps further:
In short: Vujis is not just a data provider — it’s a sales engine for exporters.

VUJIS's answer:
The story of Vujis started with its founders’ own frustration in international trade.
Before building the platform, they were trading physical commodities — mainly importing and exporting copper wire and other industrial materials.
Like many small exporters, they relied on free “buyer portals” and online directories to find leads. It didn’t take long for reality to hit: fake buyers, wasted time, and even outright scams.
That experience made one thing clear — the most reliable buyers are the ones already importing.
So the founders began studying public shipment data to identify real, verified importers and exporters. Over time, they built tools to make that process faster, smarter, and scalable with AI.
What started as a problem-solving project for their own trade business became Vujis — a platform that helps exporters worldwide find verified buyers, analyze opportunities, and reach decision-makers safely and efficiently.
VUJIS's answer:
Vujis is built using a modern, scalable tech stack designed for speed, security, and global data processing.
The platform combines AI-driven automation, secure cloud infrastructure, and modern web technologies to deliver a fast and reliable experience.
This allows Vujis to process large volumes of trade data, identify real buyers and suppliers, and help exporters take action with accurate, real-time insights — all within a clean, intuitive interface.
