Questions & Answers

As answered by people managing LeetCode and VUJIS.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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:

  • Decision Maker Emails & Phone Numbers: Gives direct emails and phone numbers of purchasing managers, not random “info@” addresses.
  • Deep Research Contact Finder: Goes beyond what’s publicly visible to uncover hidden, hard-to-find buyer contacts using AI.
  • AI Email Generator: Instantly generates personalized cold emails proven to get responses.
  • Credits System: Transparent credit-based pricing so you know exactly what you’re using and paying for.
  • Real Results: Actual users showing how Vujis helps them book meetings and close export deals.

In short: Vujis is not just a data provider — it’s a sales engine for exporters.

How would you describe the primary audience of your product?

VUJIS's answer:

The primary audience of Vujis includes:

  • Exporters and Manufacturers seeking verified global buyers to grow their international sales.
  • Importers and Distributors looking for trustworthy suppliers and verified sourcing partners.
  • Freight Forwarders who want to connect with active exporters and importers to expand their logistics network.
  • Commodity Traders exploring reliable trade intelligence and verified contacts for bulk trading.
  • B2B Sales Teams needing accurate decision-maker contact data to accelerate deal closures.
  • Trade Consultants and Agencies managing multiple client accounts who rely on verified buyer insights.
  • SMEs and Established Exporters wanting to reduce dependence on trade fairs and focus on targeted digital B2B outreach.

These professionals rely on Vujis for verified data, precision targeting, and AI-powered sales tools that drive real outcomes.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

VUJIS's answer:

Some of our biggest customers have signed NDAs and cannot be publicly disclosed.
