Software Engineering
Custom business software and mission-critical applications.
ENGINEERED CLARITY
We build, take over and operate software systems.
Software engineering, systems integration, data, measurement and marketing performance — managed as one connected business system.
REAL PROGRESS.
SOFTWARE · SYSTEMS · DATA · PERFORMANCE
One system. Five connected capabilities.
We treat software, integrations, data, performance measurement and operation as parts of the same business system — not as disconnected projects.
Systems & Integration
ERP, CRM, ecommerce, finance, logistics and external services.
Data & Measurement
Reliable data connections and business reconciliation.
Marketing Performance
From campaign activity to actual business outcomes.
Technical Ownership
Long-term operation, control and continuous improvement.
System assessment & takeover
Do not replace what you have not understood.
With an existing system, we first map how it works, its dependencies and its risks. Then we stabilise and integrate — and, where it is the right decision, take controlled technical ownership.

Marketing & Measurement
Marketing performance does not end inside the advertising platform.
Campaign → session → lead or order → payment → business outcome. Not another report, but a measurement chain you can use to make decisions.

LEADERSHIP
Experience behind the systems.
Good software is only part of a successful digital system. Technology, sales, finance and day-to-day operations have to work together.
The MENTIS LH leadership team combines decades of experience across technology, e-commerce, business operations and investment. Several members also work together as business owners, so we understand the commercial consequences of technology decisions first-hand.
Ézsiás Beatrix
Director
An economist with extensive senior management and business operations experience. Her focus is operational stability, disciplined decision-making and long-term business thinking.
Read profile
She spent six years in leadership roles across the business and technology operations of First Voice and Media Ltd, having previously served as Managing Director of First Voice Kft. in Hungary and led other businesses. For her, growth is sustainable only when it is supported by the right structure, control and operational discipline.
Ézsiás Dániel
Operations Director
With a background in economics and information technology, he brings 25 years of experience across IT, e-commerce and business leadership. He treats technology, sales, data and operations as one commercial system.
Read profile
Throughout his career, he has held operational responsibility for several digital and commerce businesses. At MENTIS LH, he connects operations, technology and innovation, focusing on making the whole system easier to understand, measure, operate and improve. He applies the same approach as an owner of EEAZI Kft., a product-led e-commerce business operating across multiple European markets.
Róna Máté
Sales Director
Part of the First Voice business environment for close to twenty years, he builds sales around careful discovery, clear communication and long-term client relationships.
Read profile
He started his career within the organisation and remains one of its longest-serving team members. His first question is not simply what can be sold, but what the client actually needs. His calm, precise and consistent way of working is particularly valuable in complex projects where good decisions depend on trust and a proper understanding of the business.
Serfőző Péter
Finance Director
An economist with substantial investment and project leadership experience. He brings an investor’s perspective to technology decisions, with a focus on sustainable commercial return.
Read profile
His background includes managing major private investment projects, primarily in real estate. At MENTIS LH, the question is not simply what a system costs, but what it delivers: whether it reduces cost, increases revenue, improves operations and ultimately produces a sustainable return. As co-owners of EEAZI Kft., he and Ézsiás Dániel also share direct experience of an e-commerce business where technology, marketing, operations and financial performance are closely connected.
One system. Different perspectives.
Can we build it? Can we operate it reliably? Will it support sales? Can we measure the outcome? And does it make commercial sense?
