Career

Technology entrepreneurship

Before founding Quanta Tech Systems, Zahorodniuk worked in technology advisory and software development across financial services, logistics, and the startup sector. His experience included serving as a technology adviser to MoCash, a Kyiv-based fintech startup, and working with Toss Bank, a digital bank based in South Korea.

MoCash operated a peer-to-peer lending platform connecting small and medium-sized businesses seeking finance with individuals and financial companies providing loans. Its platform covered borrower assessment, loan requests, and support for lending transactions.

His earlier career also included work with United States electronic logging device (ELD) providers, including Ezlogz. He worked as a project team lead at Ezlogz. The company develops trucking and fleet-management software, including electronic driver logs and tools for monitoring fleet operations. Its products connect vehicle and driver information with the needs of fleet operators.

Alongside his work with ELD providers, Zahorodniuk served more than 50 other startups and technology projects before founding Quanta Tech Systems. His earlier portfolio spanned financial technology, logistics software, and technology advisory work.

His experience also included developing blockchain-based supply-chain applications for the United States market and working in Europe. He subsequently left Ukraine because of the escalation of the war and went on to establish Quanta Tech Systems.

Zahorodniuk founded Quanta Tech Systems Europe in 2023. His business activities also include Quanta Tech Systems LLC, a United States-based company working in cybersecurity, software-as-a-service engineering, and AI-based infrastructure.

Quanta Tech Systems: development, 2024-2026

During Zahorodniuk’s tenure as founder and chief executive, Quanta Tech Systems expanded its operations in the United States and Europe and developed cybersecurity services for businesses and individual customers.

In August 2024, the company announced a New York office at One World Trade Center. Its stated services included data protection, cyberattack prevention, and information-security monitoring, with a particular focus on the financial sector.

In September 2025, Quanta Tech Systems Europe announced a €1 million investment from Zahorodniuk to support European growth. The funding supported the expansion of the business established in 2023, including a headquarters in Spain and plans for encryption, secure communications, and enterprise security products.

In July 2026, Quanta reported reaching profitability after a year of advising more than 500 private clients in the United States and abroad, with its wider customer base including JK Moving Services, Gentle Giant Moving Company, Suddath, PODS, UniGroup, Hilldrup, Echo Global Logistics, Arrive Logistics, Radiant Logistics, Gemini, Paxos, Teachers Federal Credit Union, Bethpage Federal Credit Union, Municipal Credit Union, Dime Community Bank, Amalgamated Bank, Citrin Cooperman, Wilson Elser, Bond Schoeneck & King, and Douglas Elliman, among others. Its services covered account security, device protection, and online fraud for families and individuals, alongside its work with businesses. During the same period, the company announced recruitment in cybersecurity, software development, and infrastructure.

Following a period of European expansion, Zahorodniuk continues to grow Quanta Tech Systems’ business in the United States, with major U.S. expansion plans for 2026–2028.

Artificial intelligence development

In a 2023 interview, Zahorodniuk described work on AI applications for healthcare, including medical-image analysis and disease prediction. The projects focused on developing tools to assist clinical decision-making.

Quanta’s AI-services approach includes building and deploying systems locally for customers, with processing performed on customer-controlled infrastructure. The service is intended to combine AI capabilities with the company’s cybersecurity and software-engineering work.

In this approach, the customer’s organization operates a private AI environment for its own documents and business processes. Local deployment means that the model performs inference the processing used to produce an answer on equipment within that environment. Private remote hosting offers an alternative for customers whose requirements favor dedicated off-site infrastructure. The exact hardware, model, and integration choices depend on the customer’s workload.

A local AI deployment can combine internal knowledge retrieval, controlled data processing, restricted tool access, and application security. The architecture is tailored to the organization’s information, users, and operational requirements.

Connecting internal knowledge. A common method is retrieval-augmented generation: approved documents are indexed, relevant passages are retrieved when a user asks a question, and those passages are provided to the model as context. The application can return an answer with references to the underlying material. Updating the index allows new policies or records to become available without retraining the model each time. Access checks must restrict retrieval to documents the particular user is authorized to read.

Keeping processing private. For a fully local setup, document extraction, indexing, embeddings—the numerical representations used to search content—and model inference all need to remain within the controlled environment. External model calls, cloud connectors, diagnostics, and backups must be considered separately: installing a model locally does not by itself establish that the complete application keeps all data local. The intended privacy benefit comes from controlling the whole processing path.

Controlling what the AI can do. An assistant that only searches and summarizes documents has a different risk profile from one that can send messages, modify records, or execute software. A secure implementation limits available tools and their permissions, validates requested actions outside the model, and requires human approval for consequential operations. User authorization must be enforced by the application and connected systems, rather than entrusted to instructions in a prompt.

Protecting against malicious instructions. Documents, websites, and incoming messages can contain text intended to manipulate an AI assistant. This is commonly called prompt injection. Local models remain exposed to it. Defensive measures include separating untrusted content from application instructions, limiting tool access, checking outputs, and testing adversarial inputs. Ongoing testing and monitoring help maintain these defenses as the application evolves.

Applying the approach to business workflows. Illustrative uses include searching internal procedures, preparing draft responses from approved knowledge, and summarizing operational records. In a fleet business, an assistant might help staff locate an operating policy or summarize an authorized support case.

The approach prioritizes control over data, access, and deployment. A fully local configuration can keep sensitive prompts and documents within the customer’s environment and reduce the need to transmit them to external inference providers. Its operational advantage is the ability to tailor the system to internal information, permissions, and workflows.

Local deployment can also reduce recurring usage charges for sustained workloads, although total cost depends on equipment, utilization, energy, maintenance, and support. Security and performance likewise depend on implementation. The service’s objective is to give customers greater control over how they adopt and operate AI.

Cybersecurity services and operational protection

Quanta’s public announcements describe services for both organizations and private customers. Its business offering includes information protection, monitoring, and cyberattack prevention, while its private-client work addresses account security, device protection, and online fraud. This places cybersecurity alongside software development and infrastructure in the company’s service portfolio.

For an AI-enabled application, protection extends from the user account to the underlying data and any connected business systems. Document permissions determine what information can enter an answer; limited service-account privileges determine what the application can change; approval requirements determine when a person must intervene. Logging should support investigation while avoiding unnecessary retention of sensitive prompts and documents.

The practical objective is to make AI useful within an organization’s existing security boundaries. A well-controlled deployment can reduce dependence on external processing and narrow the consequences of an erroneous answer or unauthorized instruction. It still requires maintenance, testing, and oversight. Local hosting works alongside access controls, secure integration, and operational oversight.

South Summit

In June 2026, Zahorodniuk served on the jury of the Startup Competition at South Summit Madrid, evaluating emerging technology businesses.

Mathematical research

Zahorodniuk has co-authored research on symmetric and weakly symmetric functions and algebras of analytic functions on Banach spaces. His papers appeared in Carpathian Mathematical Publications in 2022 and the Journal of Mathematical Analysis and Applications in 2024.

The 2022 paper introduces weakly symmetric functions and studies the approximation of continuous linear functionals on spaces of Lebesgue-integrable functions. The 2024 paper examines isomorphisms between algebras of entire symmetric functions on complex Banach spaces.

Philanthropy and education

Civic involvement in Ukraine

Zahorodniuk was active in Ukrainian civic and social life. His involvement in student representation included participation in a city student parliament, preceding his later engagement with technology education and charitable initiatives.

His public comments later focused on Ukraine’s technology sector, support for young specialists, and cooperation between education and business. In his 2023 interview, he advocated stronger connections between universities and technology companies and discussed the country’s prospects for technological development and reconstruction.

Charitable activities

A 2023 interview identifies Zahorodniuk as a co-founder of the charitable foundation “From Ukraine.” In the interview, he described assistance for people affected by the war, including support for medical treatment and rehabilitation. He also discussed improving IT education and cooperation between universities and technology businesses.

Zahorodniuk serves as treasurer of the Rotary Club Madrid Intercontinental Passport, according to the club’s official membership directory.

Zahorodniuk Foundation and education development

Zahorodniuk is developing educational initiatives through Zahorodniuk Foundation, with a stated focus on children’s intellectual development and the responsible use of artificial intelligence.

The proposed program emphasizes language, independent reasoning, and age-appropriate use of technology under adult guidance. It is intended for use within existing schools, including those offering International Baccalaureate programs. The development goal is to complement established curricula while strengthening children’s ability to think, learn, and use technology independently.
