Before this project, VTB clients could only check and update their personal data in person at a bank branch. Remote modifications were impossible due to high fraud risks, internal security concerns, and the lack of secure digital interfaces for customer interactions. However, the growth of digital services and the rise of fraud schemes involving identity theft required a secure and reliable solution for remote data management. The primary goal of the project was to create a system that would allow clients to verify and update their personal data remotely while minimizing the risk of unauthorized access and manipulation by fraudsters. To achieve this, the bank integrated its systems with the national digital profile via state services such as ESIA and SMEV. The use of National ID ensures secure identity verification through official government sources, preventing fraudsters from making unauthorized changes. Now, any update to personal data requires additional authentication through state services, significantly enhancing security. The project not only improved client access to their personal data but also significantly reduced fraud risks. When applying for a loan, mortgage, account, or bank card, the system automatically verifies client data against government records. Additionally, built-in regulatory compliance checks and interdepartmental data exchange detect suspicious activity and prevent fraudulent data modifications. The key innovation of this project is the ability to securely update personal data remotely without compromising security. By leveraging National ID, the bank ensures that it always works with accurate and verified client information, protecting customers from fraud and financial crimes. This initiative has strengthened cybersecurity and set a new standard for secure digital identity management in banking.

Maestra.io is nominated as Best Marketing Automation Platform for revolutionizing how e-commerce brands automate and scale their customer communications. The context for this nomination is the increasing demand for omnichannel marketing efficiency. Modern marketers juggle email campaigns, SMS alerts, push notifications, pop-ups, and more – often across disjointed tools​. This fragmentation makes it hard to deliver a cohesive message or measure impact. Maestra was built to tackle this challenge head-on by providing a cloud-based marketing automation platform that unites a CDP, loyalty program, site personalization, omnichannel communications, and more into one interface​. Over the past few years, many mid-market e-commerce brands outgrew basic email tools (like Klaviyo) but lacked the tech resources for enterprise systems; Maestra stepped in as the ideal solution, offering drag-and-drop flow building and multi-channel campaign orchestration without coding​. The platform’s ease of use (each client gets a dedicated success manager for implementation) and breadth of capability allow lean marketing teams to launch complex automated journeys that previously required entire departments. In short, Maestra provides the context of a unified, scalable marketing automation hub where all customer touchpoints can be managed intelligently. This nomination recognizes Maestra’s role in enabling brands to do more with less – executing timely, relevant marketing actions at scale, which is the essence of marketing automation. Maestra Platform Customer Testimonials: George Granoff, CEO at REKS “They are designing, delivering, and managing our customer engagement which is resulting in producing 17% of our monthly sales.” Stephanie Bregman, Vice President Marketing at 4ocean “Maestra has become an essential part of our workflow.

Instead of the usual monthly check-in and upsell, the collaboration is constant, communication is immediate, and the team is truly invested in our success.” Ceata E. Lash, CEO at PuffCuff “I’m super pleased with what we’ve achieved together and can’t recommend them enough.” Lana, Marketing Manager at Unidragon “Awesome! Effective client engagement, adaptable implementation, and rapid integration.” Jennifer Fenton, Sr Director of Marketing at Jolyn “I switched from Klaviyo and couldn’t be happier.

Yang Liu’s nomination arises from her transformative leadership in China’s rapidly evolving children’s physical education sector.

One of the unique features of this project was the argumentation of the SEO team’s solutions to the METRO team. Each task was discussed not only from an SEO benefit perspective but also from a business standpoint — how each solution could impact revenue.
This case illustrates the importance of cohesive teamwork. When everyone strives to achieve a common goal, we not only improve and optimize but also work towards business objectives.

We worked on demand, the catalog, and search visibility, achieving results that exceeded our annual plan. In 2024, non-branded SEO traffic to catalog and product pages increased by 27%, while revenue grew by 28%. We calculated revenue based on the entry page — “category|product|dynamic” within a single session.
In December 2024, we recorded a year-over-year traffic increase of 40%, and our forecast for 2025 is already 11% ahead. We have planned even more ambitious goals for 2025 compared to 2024.

In this project, we performed both basic search optimization tasks and came up with ways to scale solutions with minimal effort.
From experience, we know that in e-commerce, it’s crucial to monitor the indexing of pages to ensure that all catalog pages appear in search results. This way, users will see exactly what they are looking for. To achieve this, we set up proper indexing.
