Today, discussions about artificial intelligence have finally moved beyond theoretical forecasts and futuristic fears. For businesses, AI has transformed into a working tool that solves specific business tasks: from optimizing the average check to automating complex engineering processes. As a Google Cloud partner, the Wise IT team is at the epicenter of this transformation, helping businesses implement technologies that bring real profit.

We see a clear trend: the market is no longer interested in general-purpose “out-of-the-box” solutions. Businesses need specifics: speed of payback, security of corporate data, and the system’s ability to understand the user.

“Today, business is looking for a reliable tool that understands the context of a specific industry. We see that the highest ROI is brought by solutions built around a company’s unique data and integrated directly into its business processes.”
— Dmytro Udovyk, CTO Wise IT

In this material, we will analyze three cases in detail — VARUS.UA, NOVA Group, and Tranzzo, where the implementation of custom generative AI (GenAI) became a strategic step towards increasing business efficiency.

1. VARUS.UA: When Search Becomes “Human” and Increases Profit

The VARUS.UA team turned to Wise IT with a request to implement smart product search for users of the VARUS online marketplace, which would allow the use of natural language. Traditional search in online retail forces the buyer to adapt to the “catalog language”: entering exact SKUs, such as “potatoes” or “milk 2.5%”.

Business Challenge: From SKU to Life Scenarios

The VARUS.UA team set an ambitious task: to teach the marketplace to understand the customer at a glance. Instead of a dry list of products, the search had to learn to process “life scenarios”. The customer wants to find ingredients for a “party with friends” or a “healthy breakfast for children” without spending time manually assembling the basket.

Technological Solution

The Wise IT specialists, in cooperation with partners from !FESTCloud.ai, developed an intelligent interpreter based on the Gemini model.

Vertex AI acted as the system core, analyzing natural language queries.
The system transforms a conversational query into a structured list of relevant products, which is instantly processed by the site’s search engine.
Gemini LLM ensures contextual accuracy, offering exactly those products that match the customer’s need and mood.

Example of contextual AI search execution

Results in Figures

The implementation of AI search demonstrated significant positive dynamics within the first two months:

Popularity: 35% of users utilize the new AI search format (growing from 15% in 8 weeks).
Efficiency: The average check in orders where AI search was used increased by 18%.
Value: The average price of a product found via AI is 23% higher (130 UAH vs 106 UAH in classic search).

This proves that with AI search, users more often find interesting products and prefer higher-quality offers.

2. NOVA Group: Intelligent Ecosystem of Corporate Knowledge

For the NOVA group of companies, which includes companies in logistics (Nova Post), finance (NovaPay), IT (Nova Digital), and even aviation (Supernova Airlines), fast access to information is a matter of operational endurance.

Request: Create a “Single Source of Truth”

The scale of the NOVA group requires the systematization of a vast number of regulations, instructions, and technical documentation. The company needed a centralized resource where every employee, from a courier to a top manager, could instantly find the answer to a work question.

Solution: Google Sites + Vertex AI Search

The Wise IT team implemented a comprehensive project that combined interface simplicity and administration with the power of generative AI:

Structured Portal: An intuitive website with sections by positions, thematic areas, and terminology was created on the basis of Google Sites.
Intelligent Search: Thanks to Vertex AI Search, employees gained the ability to ask questions in natural language. The system provides not just a list of files, but a specific, meaningful answer based on internal documents.
Security and Relevance: Search is limited exclusively to the company’s knowledge base, which eliminates the risk of AI “hallucinations”. Data is automatically synchronized with Google Drive, ensuring content relevance 24/7.

Business Benefits

Acceleration of Onboarding: New employees get up to speed faster thanks to the “By Position” section.
Time Savings: The time to find the necessary instruction has been reduced manifold.
Training: Wise IT specialists conducted two-stage training for the NOVA team, allowing them to independently administer the platform without programming skills.

3. Tranzzo: Automating Code Review in a World of High Requirements

Tranzzo is a global payment platform that processes over 10 million transactions monthly. In fintech, the speed of releasing new features must balance with impeccable code security – PCI DSS standards.

Challenge: Delays in Development

As the business grew, the traditional Code Review process began to slow down releases. Senior engineers spent too much time on routine code checks, which distracted them from strategic architecture.

Solution: Custom AI Reviewer

Wise IT acted as an architectural partner in creating an in-house tool based on Gemini 1.5 Pro, deployed entirely within Tranzzo’s secure perimeter on Google Cloud.

The project was implemented in three phases:

Phase 1: Training the system to react to Pull Requests and analyze tasks from Jira.
Phase 2: Deepening context. AI was taught to account for project architectural patterns and rules described in special regulatory files.
Phase 3: Scaling to all development teams.

Interaction algorithm of system elements: from activation via PR-trigger and context collection to cyclic code analysis by LLM model and automatic publication of results.

Result and Global Recognition

In just one month, the company obtained a tool that became a full-fledged assistant for developers:

Time to merge code (time-to-merge) was reduced by 30%.
54% of AI recommendations are accepted by engineers without corrections.
The case was included in the Google Cloud EMEA SMB AI Playbook as one of the best examples of AI solutions for business in the region.

Why Google Cloud?

These cases are united by the use of the Google Cloud platform, which provides fundamental advantages to business:

Economic Flexibility (Pay-as-you-go): Business pays only for the resources used. This eliminates the need for large initial investments in infrastructure.
Security and Data Sovereignty: Corporate data is never used to train public Google models. Your intellectual property remains fully isolated.
Access to Gemini and Vertex AI: The most advanced generative AI models are integrated directly into business logic through convenient APIs.
